The 0.6/1 Kv PVC insulated and sheathed Nyby double steel tapes armoured cable is a low-voltage power transmission cable integrating multiple protections and stable performance, specially designed for power distribution in complex environments. Its unique structural design and material selection enable it to show significant advantages in mechanical protection, insulation performance and applicable scenarios, and it is widely used in industrial, civil and outdoor occasions.​ In terms of specification parameters, the rated voltage of the cable is 0.6/1 Kv, which perfectly fits the low-voltage power distribution system and can meet the power transmission needs of most industrial equipment, buildings and outdoor facilities. Its conductor usually uses high-purity electrolytic copper, and common specifications cover multi-core structures, such as 4×25mm², 4×50mm², 4×70mm², etc., to adapt to different power transmission requirements. Taking the 4×50mm² specification as an example, at an ambient temperature of 25℃, the long-term allowable current-carrying capacity of each core is about 150A, corresponding to a power of about 33kW, which is sufficient to support the stable operation of medium-sized electrical equipment clusters. The outer diameter of the cable varies according to specifications. Taking 4×50mm² as an example, the outer diameter is about 45mm, among which the PVC insulation layer thickness is about 1.8mm, the inner PVC sheath thickness is about 2.0mm, the outer steel tape armouring thickness is about 0.5mm, and the outermost PVC sheath thickness is about 2.2mm. The overall structure is compact, ensuring good mechanical strength and insulation performance. In addition, the cable's short-circuit withstand temperature can reach 80℃, and it can maintain stable operation under short-term overload conditions, ensuring the continuity of power transmission.​ In terms of materials and structure, the core advantage of the cable lies in the "double protection" design. The conductor is made of electrolytic copper with a purity of ≥99.9%, which has excellent conductivity, reduces transmission loss, and has good ductility, making it easy to bend and lay. Both the insulation layer and the inner sheath are made of PVC material. The PVC insulation layer can work for a long time in a 70℃ environment, with high insulation resistance, effectively preventing electric leakage; the inner sheath further enhances the insulation performance and provides an attachment basis for the steel tape armouring. The middle double steel tape armouring is its core protective structure, which is made of high-strength cold-rolled steel tape, formed by spiral winding or longitudinal wrapping process. It can not only resist external mechanical impact, extrusion and puncture, but also enhance the tensile strength of the cable, making it suitable for various laying methods such as direct burial, pipe 穿，or overhead. The outermost PVC sheath has weather resistance and corrosion resistance, which can protect the armoured layer from moisture, ultraviolet rays and chemical erosion, and prolong the service life of the cable.​ In terms of characteristic uses, relying on the strong protection of steel tape armouring, the cable performs well in outdoor and complex environments. In industrial plants, it can be used for connecting lines between workshops and outdoor equipment, such as connecting water pumps, fans and other open-air installed machinery, resisting heavy object rolling or equipment collision; in municipal engineering, it is suitable for underground direct burial power distribution trunks, such as community power distribution and street lamp system power supply, withstanding soil pressure and groundwater erosion; in the construction field, it can be used as vertical power distribution cable in high-rise buildings, laid along cable shafts, bearing its own weight and possible external impact; in addition, in agricultural irrigation systems, temporary construction sites and other scenarios, its durability and easy maintenance can also meet long-term use needs.​ Compared with ordinary PVC cables, the Nyby steel tape armoured cable has a significant advantage in the leap of mechanical protection ability, which can adapt to harsher laying environments and reduce faults caused by external damage; at the same time, it retains the characteristics of low cost and convenient processing of PVC materials, combining economy and reliability. However, its weight is higher than that of ordinary cables, so mechanical assistance is needed during laying, and PVC materials still have the limitation of releasing gas at high temperatures, so they are not suitable for high-temperature places or places with extremely high fire protection levels.​ In conclusion, the 0.6/1 Kv PVC insulated and sheathed Nyby double steel tapes armoured cable, with its reasonable specification design, solid armoured structure and wide applicability, has become an ideal choice for dealing with complex environments in low-voltage power distribution systems, providing a solid guarantee for the safety and stability of power transmission.

Steel Wire Armoured (SWA) and Steel Tape Armoured (STA) power cables are two types of armoured cables widely used in power transmission. With their unique armouring structures, they possess excellent mechanical protection performance and environmental adaptability, suitable for various complex scenarios.​ SWA armoured cables use multiple strands of galvanized steel wires as the armouring layer. The steel wires are usually spirally wound around the cable core. This structure endows the cable with excellent tensile and impact resistance, effectively withstanding longitudinal tension and external impacts during laying and use. The number and diameter of steel wires in the armouring layer vary with the cable specifications to match different mechanical strength requirements. STA armoured cables, on the other hand, adopt steel tape armouring. The steel tape wraps around the cable core through longitudinal wrapping or spiral winding, forming a solid protective layer. It mainly provides radial pressure resistance, effectively resisting external radial forces such as soil pressure and rodent bites.​ In terms of structure, both types of armoured cables consist of conductors, insulation layers, filling layers, inner liners, armouring layers, and outer sheaths. The conductors are mostly high-purity copper or aluminum, ensuring good conductivity. The insulation layers are commonly made of XLPE (cross-linked polyethylene) or PVC (polyvinyl chloride), with excellent electrical insulation properties. The filling layers and inner liners are used to fix the cable core and buffer external forces. The outer sheath is usually PVC or PE (polyethylene), which has acid and alkali resistance, corrosion resistance and other characteristics, further protecting the armouring layer and internal structure.​ In terms of performance, the rated voltage of SWA and STA armoured cables ranges from 0.6/1kV to 110kV, meeting the needs of low-voltage and medium-voltage power transmission. Their long-term operating temperature depends on the insulation material. XLPE insulated cables can reach 90℃, PVC insulated cables are 70℃, and both can withstand higher temperatures in case of short circuits (250℃ for XLPE and 160℃ for PVC). In terms of mechanical properties, the tensile strength of SWA cables is significantly higher than that of STA cables, making them more suitable for scenarios requiring large tensile force, such as direct burial crossing rivers and bridges. STA cables have outstanding radial pressure resistance, suitable for underground direct burial environments with high soil pressure.​ In application scenarios, SWA armoured cables are often used in occasions that need to bear tension, such as underground direct burial crossing railways and highways, vertical wiring in high-rise buildings, and connecting lines of mobile equipment in ships and mines. STA armoured cables are widely used in ordinary underground direct burial laying, such as urban distribution networks, power transmission in industrial parks, and main lines in residential communities, which can effectively cope with soil extrusion and external mechanical damage. In addition, both types of cables are suitable for humid, dusty and corrosive environments, such as chemical parks and sewage treatment plants. The combined protection of the armouring layer and outer sheath enables them to operate stably for a long time.​ In terms of installation and maintenance, attention should be paid to the bending radius when laying SWA and STA armoured cables to avoid excessive bending damaging the armouring layer and insulation layer. Due to the characteristics of steel wire armouring, SWA cables are relatively difficult to bend and require special tools; STA cables are slightly more flexible, but they also need to follow installation specifications. After laying, insulation resistance test and withstand voltage test should be carried out to ensure the cable is in good condition. In daily maintenance, it is necessary to regularly check whether the outer sheath is damaged and whether the armouring layer is rusted. For cables exposed to harsh environments, anti-corrosion and anti-erosion measures should be taken to extend their service life.​ In conclusion, SWA and STA armoured power cables play an important role in different power transmission scenarios with their unique armouring structures and performance advantages, providing a reliable guarantee for the safe and stable operation of power systems.

The long-term allowable operating temperature is 70℃, and it can withstand 160℃ high temperature in case of short circuit (within 5 seconds), which can meet the temperature requirements of most low-voltage scenarios. Outside the insulation layer is a PVC armoured layer, which forms a solid protection through steel tape or steel wire winding, effectively resisting external mechanical impact, soil extrusion and rodent bites, and protecting the internal conductors and insulation layers from damage. The outermost layer is a PVC sheath, which further enhances waterproof and anti-corrosion capabilities, ensuring the cable operates stably in humid, dusty and other environments.​ In terms of performance, the rated voltage of the cable is 0.6/1kV, suitable for low-voltage distribution systems with AC 50Hz/60Hz. The current-carrying capacity of the 4X6mm² specification is about 40-50A when laid in air, and about 35-45A when directly buried in soil, which can meet the power transmission needs of small and medium-sized equipment and multi-storey residences. Its insulation resistance exceeds 500MΩ·km, and the dielectric loss tangent is low, ensuring small energy loss during power transmission. In terms of mechanical properties, the minimum bending radius is 12 times the cable outer diameter (for fixed laying), which can adapt to installation in narrow spaces; the combination of the armoured layer and the sheath makes the cable have strong tensile strength and impact resistance, and can withstand certain stretching and extrusion during laying.​ In terms of price, the pricing of this cable is affected by factors such as raw material costs, production processes, specifications and models, purchase volume, and market supply and demand. As the main conductor material, copper's market price fluctuations directly affect the cable cost. When copper prices rise, cable prices usually adjust accordingly. Different specifications (such as whether to include 8mm² conductors) have different prices. The 4X6mm²+1X8mm² cable has a slightly higher price than the 4X6mm² specification due to the increased conductor usage. In addition, bulk purchases can enjoy certain discounts, while customized needs (such as special lengths and sheath colors) may lead to price increases. Currently, the unit price of this cable is roughly in the range of 10-30 yuan per meter, and the specific price needs to be negotiated with the supplier according to the actual purchase situation.​ In application scenarios, the 4X6mm² specification cable is often used in household main lines of multi-storey residences, distribution lines of small shops, lighting and air conditioning branch lines of office buildings, etc.; the specification including 8mm² conductors is suitable for scenarios requiring separate grounding, such as control circuits of industrial equipment, power distribution of fire protection systems in commercial complexes, etc. Due to the protective characteristics of PVC armouring, the cable can be laid in various ways such as direct burial, pipe laying, and bridge laying, adapting to different installation environments such as underground, walls, and ceilings, and performs stably especially in outdoor or humid areas with high protection requirements.​ In terms of installation and maintenance, excessive bending or dragging should be avoided during laying to prevent deformation of the armoured layer or damage to the insulation layer; special copper joints should be used for connection to ensure good conductivity and tight sealing to avoid moisture intrusion. After installation, insulation tests and voltage withstand tests must be carried out to confirm that the performance meets the standards. In daily maintenance, regularly check the appearance of the cable. If sheath damage, armoured layer rust and other conditions are found, timely repair or replacement is required to extend the service life.​ In summary, the PVC Cable 4X6mm²/4X6mm 8mm Cu PVC Armoured Power Cable has certain competitiveness in price, and its performance meets the needs of low-voltage power distribution. It is a cost-effective cable choice, providing a reliable and economical solution for various low-voltage power transmission scenarios.

The YJY23-0.6/1kV 3×25mm² armoured power cable is a robust and versatile electrical cable designed for reliable low-voltage power transmission in demanding environments. Its designation breaks down key features: "YJY" indicates a cross-linked polyethylene (XLPE) insulated, polyvinyl chloride (PVC) sheathed cable, while "23" denotes a double steel tape armouring layer, ensuring enhanced mechanical protection. Rated for 0.6/1kV, it operates with a maximum phase-to-ground voltage of 0.6kV and phase-to-phase voltage of 1kV, making it suitable for a wide range of industrial, commercial, and infrastructure applications. At the core of this cable are three 25mm² copper conductors, each crafted from high-purity electrolytic copper (purity ≥99.95%) to ensure excellent electrical conductivity (≥100% IACS). The 25mm² cross-sectional area provides a substantial current-carrying capacity, typically around 85A under normal operating conditions (30°C ambient temperature), with derating factors applied for higher temperatures or bundled installations. This capacity allows the cable to efficiently power medium to large electrical systems, such as industrial machinery, commercial building distribution networks, and outdoor utility connections. Each copper conductor is individually insulated with XLPE, a material renowned for its superior thermal and electrical properties. XLPE insulation offers a high dielectric strength (≥20kV/mm) to prevent electrical breakdown, excellent resistance to heat (operating temperature range of -40°C to 90°C), and immunity to moisture and chemical degradation. This insulation ensures reliable performance even in harsh environments, including areas with high humidity, exposure to oils, or moderate chemical presence. A defining feature of the YJY23 cable is its double steel tape armouring (the "23" in its designation). This armouring consists of two layers of galvanized steel tape, applied helically around the insulated conductors with overlapping edges to form a continuous protective barrier. The steel tape provides exceptional mechanical strength, resistance to impact, and protection against rodent or mechanical damage—critical for cables installed in underground trenches, concrete encasements, or industrial areas with heavy machinery. The armouring also enhances the cable’s tensile strength, making it suitable for direct burial or installation in areas where physical stress is likely. Over the steel armouring, an outer PVC sheath provides an additional layer of protection. This sheath is resistant to UV radiation, weathering, and abrasion, making the cable suitable for both indoor and outdoor applications. The PVC sheath also acts as a moisture barrier, preventing water ingress into the armouring and conductors, which is essential for maintaining long-term performance in damp or underground environments. The structural design of the YJY23-0.6/1kV 3×25mm² cable balances flexibility and durability. While the steel armouring adds rigidity compared to unarmoured cables, the overall construction allows for a minimum bending radius of 12 times the cable’s outer diameter (approximately 150mm for this specifications), facilitating installation in confined spaces or around obstacles. The three conductors are twisted together to form a compact core, reducing the cable’s overall diameter and simplifying handling during installation. In terms of performance, this cable excels in low-loss power transmission. The high conductivity of the copper conductors and the low dielectric loss of XLPE insulation minimize energy dissipation, ensuring efficient power delivery over distances up to 100 meters without significant voltage drop. The steel armouring also provides partial electromagnetic shielding, reducing interference with nearby signal cables—a valuable feature in industrial settings with complex electrical systems.

Low-voltage electrical systems form the backbone of power distribution in residential complexes, commercial buildings, industrial facilities, and infrastructure projects—demanding cables that balance safety, durability, and reliable performance. The YJV32 Steel Wire Armored (SWA) 2-Core Copper XLPE Low-Voltage Electrical Cable—available in conductor cross-sectional areas of 2.5mm², 10mm², and 16mm², and featuring a 2-core earth armored power design—stands out as a robust solution tailored to these demands. Engineered to withstand mechanical stress, environmental hazards, and low-voltage power transmission needs (typically 0.6/1kV), this cable integrates high-purity copper conductors, cross-linked polyethylene (XLPE) insulation, and a steel wire armor layer to deliver long-term reliability in diverse low-voltage applications. This abstract explores the cable’s technical specifications, material innovations, armored protection advantages, application versatility, and safety features, highlighting why it is a preferred choice for low-voltage power distribution and grounding systems. At the core of the YJV32 cable’s design is its 2-core copper conductor configuration, with conductor sizes optimized for varying low-voltage load requirements. The conductors use high-purity electrolytic copper (99.95% minimum purity)—a material selected for its exceptional electrical conductivity (63.1S/m at 20°C) and low resistance, ensuring minimal power loss (≤2% per 100m) during transmission. The 2.5mm² variant supports a continuous current rating of 24A–28A (in air, 30°C ambient temperature), making it ideal for residential branch circuits (e.g., powering lighting, small appliances like refrigerators or televisions) and low-load commercial applications (e.g., office cubicle power outlets). The 10mm² conductor, with a current rating of 60A–65A, caters to medium-load scenarios such as commercial building main power lines (connecting distribution boards to floor-level subpanels) or industrial auxiliary systems (e.g., conveyor belt motors, small pumps). The 16mm² conductor, rated for 80A–85A, handles higher loads, including industrial machinery power supply (e.g., 5kW air compressors) and commercial HVAC auxiliary circuits. Each conductor features a stranded structure (Class 2 per IEC 60228)—composed of multiple thin copper strands twisted together—to enhance flexibility (minimum bending radius: 12× cable outer diameter) and resistance to fatigue from mechanical stress, simplifying installation in tight spaces (e.g., wall cavities, underground ducts) and reducing the risk of conductor breakage. A defining feature of the YJV32 cable is its multi-layer protective structure, engineered to shield the conductor and insulation from external damage and environmental threats. The innermost layer is cross-linked polyethylene (XLPE) insulation—a material renowned for its superior electrical insulation properties, thermal stability, and moisture resistance. The XLPE insulation (thickness: 0.8mm for 2.5mm², 1.2mm for 10mm², 1.4mm for 16mm²) exhibits a dielectric strength of ≥20kV/mm, preventing current leakage even in humid or damp environments. It also operates reliably across a wide temperature range (-40°C to 90°C), withstanding seasonal temperature fluctuations and localized heat generation from conductors. Surrounding the XLPE insulation is a binder tape layer (typically polyester or fiberglass) that secures the insulation and provides a smooth base for the armor. The key protective component—the steel wire armor (SWA)—consists of galvanized steel wires (diameter 0.8mm–1.2mm) twisted around the binder tape in a 1+6 or 1+6+12 configuration. This armor layer delivers exceptional mechanical protection: it resists impact from construction tools, abrasion from underground rocks or concrete, and damage from rodents (a common hazard in residential and industrial settings). The galvanized coating on the steel wires (zinc thickness ≥80g/m²) adds corrosion resistance, ensuring durability even in humid or underground environments. Completing the structure is an optional PVC outer sheath (thickness 1.0mm–1.5mm) for additional moisture and chemical resistance, though the SWA layer itself provides primary mechanical protection—making the cable suitable for direct burial, duct installation, or exposed routing in industrial yards. The YJV32 cable’s 2-core earth armored power design is a critical safety feature, integrating grounding functionality directly into the cable structure. Unlike traditional cables that require separate grounding wires, the YJV32’s 2-core configuration includes one core for power transmission and the second core for protective grounding—simplifying installation and ensuring compliance with low-voltage safety standards (e.g., IEC 60364, NEC 2023). The grounding core, constructed from the same high-purity copper as the power core, provides a low-resistance path for fault currents (e.g., short circuits), directing excess current to the ground and triggering circuit breakers or residual current devices (RCDs) to shut off power—preventing electric shocks and equipment damage. The steel wire armor further enhances grounding performance: it acts as a supplementary earth conductor, reducing grounding resistance and ensuring rapid fault current dissipation. This integrated design is particularly valuable in industrial settings, where equipment grounding is critical for worker safety, and in residential areas, where simplified installation reduces labor costs and minimizes the risk of grounding errors. Application versatility is another key advantage of the YJV32 cable, making it suitable for a wide range of low-voltage scenarios. In residential construction, the 2.5mm² variant is used for branch circuits (lighting, outlets), while the 10mm² variant powers main distribution lines (connecting the utility meter to the main distribution board). The cable’s armor layer protects against damage during home renovations (e.g., drilling or hammering near walls) and resists rodent bites in crawl spaces. In commercial buildings (e.g., shopping malls, offices), the 16mm² YJV32 cable distributes power to floor-level subpanels, with its armor ensuring durability in high-traffic areas (e.g., under floor tiles, in ceiling voids). In industrial facilities, the cable is deployed to power auxiliary machinery (pumps, conveyors) and connect control systems, where its steel wire armor withstands impact from heavy equipment and abrasion from industrial debris. It is also ideal for infrastructure projects such as street lighting, traffic signal systems, and underground power distribution in urban areas—its direct burial capability eliminating the need for costly conduit installation. Safety and compliance are non-negotiable for low-voltage cables, and the YJV32 meets rigorous international standards to ensure reliable performance. It complies with IEC 60502-1 (low-voltage power cables for fixed installations) and GB/T 12706.1 (Chinese national standard for low-voltage cables), with key safety tests including: insulation resistance (≥100MΩ·km at 500V DC), withstand voltage (3kV AC for 5 minutes without breakdown), and flame retardancy (complying with IEC 60332-1, self-extinguishing within 30 seconds of ignition source removal). The steel wire armor also enhances fire safety by limiting flame spread, while the copper conductors’ low resistance reduces heat buildup—minimizing the risk of cable overheating and fire. In summary, the YJV32 Steel Wire Armored 2-Core Copper XLPE Low-Voltage Electrical Cable (2.5mm², 10mm², 16mm²) with 2-core earth armored power function delivers a rare balance of safety, durability, and versatility for low-voltage power distribution. Its high-purity copper conductors ensure efficient power transmission, XLPE insulation provides reliable electrical isolation, and steel wire armor offers robust mechanical protection—making it suitable for residential, commercial, industrial, and infrastructure applications. The integrated 2-core earth design simplifies installation and enhances safety, while compliance with global standards guarantees peace of mind for engineers, contractors, and end-users alike. For low-voltage systems demanding long-term reliability and protection against harsh conditions, this cable represents a trusted and cost-effective solution.
