This product is a BV Cable with 1.5mm² single core solid copper wire, a core power transmission component specially designed for indoor household wiring. It adopts a single-core solid copper conductor and a flame-retardant PVC insulation layer, with the conductor cross-section accurately set to 1.5mm². It is suitable for low-load electricity consumption scenarios such as household lighting circuits and small household appliance power supply. Relying on stable conductive performance, excellent flame-retardant characteristics, and convenient installation advantages, it provides a safe, reliable, and long-term wiring solution for the indoor circuit systems of civil buildings such as residences, apartments, and villas, and is an indispensable basic electrical material in household electrical decoration.​ In terms of core specifications and structural design, the wire features a "single-core solid" core structure, with a uniform conductor cross-section of 1.5mm². This parameter is accurately calculated based on household electricity load—the 1.5mm² solid copper conductor has a stable current-carrying capacity (the long-term safe current-carrying capacity can reach 10-16A under normal temperature environment), which fully meets the electricity demand of household lighting fixtures (such as LED lights and ceiling lights, with power usually ranging from 10-100W) and small sockets (used for low-power equipment such as mobile phone chargers, desk lamps, and routers). At the same time, it avoids material waste and increased wiring difficulty caused by excessively large conductor cross-sections. Compared with multi-core flexible wires, the single-core solid structure has stronger shape stability, and is less prone to problems such as scattered conductors and knots during pipe threading wiring. It is especially suitable for concealed wiring scenarios on household walls and floors, and can accurately pass through narrow threading pipes, reducing line loss and fault risks during construction.​ The solid copper conductor is the core material advantage of this wire. Made of high-purity electrolytic copper with a purity of more than 99.95%, it has three core values: First, excellent electrical conductivity. The resistivity of high-purity copper is much lower than that of ordinary copper alloys or aluminum conductors, which can effectively reduce resistance loss during current transmission and reduce power waste caused by heat generation. Especially in long-term energized lighting circuits, it can avoid accelerated aging of the insulation layer due to conductor heat generation. Second, outstanding mechanical strength. The solid copper conductor has high hardness, stable tensile and bending resistance. It can withstand a certain degree of mechanical tension during wiring (such as dragging during pipe threading) and is not prone to conductor breakage or deformation due to slight collisions, ensuring long-term conductivity of the line. Third, good oxidation resistance. The surface of high-purity copper is easy to form a dense oxide film, which can isolate oxygen and moisture in the air, prevent internal oxidation and corrosion of the conductor, extend the service life of the wire, and adapt to the long-term use demand of household circuits for 15-20 years.​ The selection of flame-retardant PVC insulation layer is specially optimized for household electricity safety needs: First, the flame-retardant performance meets the Class B or Class C flame-retardant standards in the national standard GB/T 19666-2019 "General Rules for Flame-Retardant and Fire-Resistant Wires and Cables". When encountering an open flame, the insulation layer can self-extinguish quickly without generating a large amount of toxic smoke, effectively preventing the spread of fire along the wire and gaining valuable time for personnel escape and property protection in household fire accidents. Second, the PVC insulation layer has excellent electrical insulation performance, with an insulation resistance of more than 1000MΩ, which can effectively isolate the conductor from contact with the outside world, prevent leakage accidents (such as avoiding electric shock when the wire is damaged), and at the same time avoid signal interference between different lines (although household wiring is mainly for strong electricity, the insulation layer can reduce capacitive coupling interference between lines). In addition, the PVC insulation layer also has a certain degree of temperature resistance and corrosion resistance, and can work stably in the temperature range of -15℃ to 70℃, adapting to household environments with large temperature differences or high humidity such as kitchens and bathrooms. It can also resist slight chemical corrosion in daily cleaning (such as detergent residues) and protect the internal conductor from damage.​ In terms of adaptability to application scenarios, the core value of this wire lies in "accurately matching the diverse needs of household wiring": In lighting circuits, it can be used as the main line or branch line to connect the distribution box with lighting fixtures and switches in various rooms. The single-core solid structure is convenient for laying in the threading pipes of ceilings and walls, and its hardness is moderate, which can be easily and firmly connected to terminals, avoiding lamp flickering caused by poor contact. In small socket circuits, it is suitable for ordinary sockets in living rooms, bedrooms, studies and other areas, supplying power to low-power equipment such as mobile phone chargers, laptops, and small household appliances. The 1.5mm² conductor cross-section can meet the current demand of the equipment, and the flame-retardant insulation layer reduces the risk of fire caused by socket short circuits. In household secondary decoration or line transformation, the single-core structure of the wire is convenient for docking with the original line, and the PVC insulation layer has a variety of colors (commonly red, blue, yellow, etc., which can distinguish live wires, neutral wires, and ground wires), which is convenient for construction personnel to identify the line function and reduce wiring errors.​ From the perspective of installation and use convenience, this wire has significant advantages: The single-core solid copper conductor has moderate hardness, so copper wires are not easy to scatter when stripping, and can be quickly connected to electrical components such as terminals, switches, and sockets. The contact is tight, reducing contact resistance. The surface of the PVC insulation layer is smooth, with low friction during pipe threading, which can reduce wear with the inner wall of the threading pipe. At the same time, the insulation layer has good toughness and is not easy to crack due to bending. In addition, the outer skin of the wire is usually printed with clear marks (such as model, specification, manufacturer, production date, etc.), which is convenient for construction personnel to check product information and ensure compliance with the standard requirements of household wiring.​ In terms of overall value, this BV 1.5mm² single-core solid copper wire solves three core pain points of household wiring through the combination of "accurate specifications + high-quality materials + safety design": First, the "safety hazard" problem. The flame-retardant insulation and high-purity copper conductor reduce the risk of leakage and fire. Second, the "construction complexity" problem. The single-core solid structure simplifies the pipe threading and wiring process, improving construction efficiency. Third, the "long-term reliability" problem. The anti-oxidation and temperature-resistant material characteristics ensure the long-term stable operation of the line and reduce the later maintenance cost. For household users, this wire is not only a "current transmission carrier" but also a key basic material to ensure household electricity safety and improve living experience, providing a solid guarantee for the stable operation of the household electrical system.

Combining cost-effectiveness with reliable performance, this wire is a practical choice for straightforward wiring needs where a sheath is unnecessary.

The H05V-U and H07V-U single core solid copper cables focused on in this abstract are standardized PVC insulated electrical wires specifically designed for building and industrial electricity scenarios. With solid copper conductors, a rated operating temperature of 70°C, a PVC insulation structure, and the cost advantage of factory direct supply, they have become core basic wires for indoor building wiring, industrial equipment power supply, and electrical control systems. They are widely suitable for diverse electricity needs in residences, commercial buildings, factory workshops, and other scenarios, and occupy an important position in electrical installation projects.​ In terms of voltage rating and model differences, both cables fall into the low-voltage electrical wiring category, but their voltage adaptation ranges have different focuses: The rated voltage of H05V-U is 300/500V, where "300V" represents the rated insulation voltage of the conductor to the ground or neutral wire, and "500V" represents the rated insulation voltage between conductors. It is more suitable for low-power electricity scenarios in buildings (such as lighting circuits and ordinary sockets); The rated voltage of H07V-U is 450/750V, which has stronger voltage-carrying capacity and can meet the electricity needs of industrial equipment (such as small motors and control cabinets) and main power distribution circuits in buildings. Together, the two cover a wide power supply range from low-voltage low-power to medium-low voltage medium-power, providing accurate voltage adaptation solutions for different scenarios. The "V-U" identifier in the model clearly indicates its insulation and sheath characteristics - "V" stands for PVC insulation, and "U" stands for no sheath (the single-core structure does not require an additional sheath, and the insulation layer directly serves as the outer protection), simplifying the product structure while ensuring basic protection performance.​ In terms of conductor and insulation layer design, both cables use solid copper as the conductor material, which is a core feature distinguishing them from multi-strand flexible wires. The solid copper conductor is made of high-purity electrolytic copper (purity ≥99.95%), with extremely low resistivity (≤0.017241Ω·mm²/m at 20°C), excellent electrical conductivity, and low current transmission loss. It can effectively reduce conductor heating and avoid insulation aging caused by overheating; At the same time, the solid structure has higher mechanical strength and is not prone to breakage due to bending or pulling, making it particularly suitable for the "fixed laying" needs in building and industrial scenarios (such as threading through walls and cable tray wiring). After installation, it has strong stability and is not prone to problems such as poor contact during long-term use. The conductor cross-sectional area covers a variety of specifications (such as 0.75mm², 1.0mm², 1.5mm², 2.5mm², 4mm²), which can be flexibly selected according to the load current: The 0.75mm²-1.5mm² specifications of H05V-U are suitable for lighting and small household appliance sockets; The 2.5mm²-4mm² specifications of H07V-U are suitable for power supply of industrial equipment and main building circuits, ensuring accurate matching between current-carrying capacity and load requirements.​ The insulation layer is made of PVC (polyvinyl chloride) material, with a rated operating temperature of 70°C. This design fully considers the temperature characteristics of building and industrial environments. The PVC insulation layer has good electrical insulation performance (volume resistivity ≥1×10¹²Ω·cm, dielectric loss tangent ≤0.08 at 50Hz), which can effectively isolate the conductor from the external environment and avoid the risk of electric leakage; The rated operating temperature of 70°C can cope with common temperature fluctuations in scenarios (such as high indoor temperatures in summer and heat dissipation from industrial equipment), and can also maintain insulation stability during short-term overload without softening or breakdown. In addition, the PVC insulation layer also has a certain degree of flame retardancy (oxygen index ≥24%), meeting flame retardant standards such as GB/T 18380, which can slow down flame spread and improve electricity safety in building and industrial scenarios; Its surface is smooth, with low friction during threading installation, which can improve construction efficiency. At the same time, it has good chemical corrosion resistance, which can resist common dust, slight moisture in buildings, and mild oil pollution in industrial environments, extending the service life of the wire.​ In terms of product positioning and the advantages of factory direct supply, the two cables take "building & industrial use" as their core positioning. The production process strictly complies with international standards (such as IEC 60227-1) and domestic standards (such as GB/T 5023.1). From raw material selection (copper purity, PVC particle quality) to production processes (conductor drawing, insulation extrusion), multiple quality inspections are carried out to ensure that the conductive performance, insulation performance, and mechanical performance of each batch of products meet the standards. The factory direct supply model eliminates the intermediate distributor link, which not only reduces product costs (the price is 10%-15% lower than that of products in the market circulation) but also shortens the delivery cycle (delivery of conventional specifications within 7-10 days, customized specifications within 15-20 days). At the same time, it supports on-demand customization (such as cutting to specific lengths and customizing color identification) to meet the bulk procurement needs of construction projects and the personalized needs of industrial enterprises. In addition, factory direct supply also provides more direct technical support, such as recommending suitable specifications according to project needs and providing installation guidance, further improving the product use experience.​ Overall, the H05V-U and H07V-U single core solid copper cables (70°C PVC insulated) provide a safe, stable, and efficient wiring solution for building and industrial electricity scenarios through accurate voltage adaptation, high-quality solid copper conductors and PVC insulation, flexible specification selection, and the cost-effective advantage of factory direct supply. Whether it is residential lighting, commercial building power distribution, or factory equipment power supply, they can rely on their reliable performance and cost advantages to become the preferred wires for electrical installation projects, helping to improve the safety and stability of building and industrial electrical systems.

The 1.5/2.5/4/6 mm² single core copper conductor PVC insulated electrical wire is a standardized electrical cable specifically designed for house wiring and low-voltage power distribution scenarios. With a rated voltage of 450/750V and CE certification, it is widely applicable to power transmission needs in home decoration, commercial housing construction, and small-scale commercial premises, providing stable and reliable power supply support for lighting circuits, socket systems, and small to medium-sized electrical equipment. In terms of core specifications and performance, this series of cables covers four commonly used cross-sectional areas: 1.5mm², 2.5mm², 4mm², and 6mm², which can be flexibly selected according to different electrical loads. The 1.5mm² model has a long-term allowable current-carrying capacity of approximately 18A, suitable for low-power scenarios such as bedroom lighting and small household appliances (e.g., table lamps, mobile phone chargers). The 2.5mm² model has a current-carrying capacity of about 25A, which can meet the needs of medium-power equipment such as living room sockets, electric kettles, and printers, with a maximum load of 5.5kW under 220V voltage. The 4mm² model’s current-carrying capacity is increased to 32A, applicable to high-power kitchen appliances (e.g., microwaves, rice cookers) and bathroom water heaters. The 6mm² model has a current-carrying capacity of up to 40A, which can undertake heavy-load circuits such as the main incoming line of the entire house and wall-mounted air conditioners, effectively avoiding conductor heating and insulation aging caused by overload. All conductors are made of high-purity electrolytic copper with a purity of ≥99.95%, featuring a single-core solid structure (with diameters of approximately 1.38mm, 1.78mm, 2.25mm, and 2.76mm respectively). They have extremely low resistivity (≤0.017241Ω·mm²/m at 20℃), resulting in low current transmission loss and no easy performance degradation due to heating during long-term use. The insulation layer is made of modified polyvinyl chloride (PVC) material, optimized to adapt to the complex environment of residences. Its flame-retardant grade complies with the GB/T 18380.1-2008 Class C standard, with an oxygen index of ≥24%. It can self-extinguish within 60 seconds in the vertical combustion test without molten drips, effectively preventing flames from spreading along the cable and reducing the risk of electrical fires in areas such as kitchens and bedrooms. At the same time, it has excellent electrical insulation performance, with a volume resistivity of ≥1×10¹²Ω·cm and a dielectric loss tangent of ≤0.08 at 50Hz. Even in humid environments like bathrooms and kitchens, it can isolate the conductor from the outside world to avoid electric leakage accidents. The insulation layer has a long-term operating temperature of 70℃ and can withstand high temperatures of 160℃ for 5 seconds during short-term overload, which can cope with local high temperatures caused by equipment heat dissipation or seasonal temperature differences and prevent insulation cracking and hardening. Its smooth surface can also reduce friction resistance during piping, improving construction efficiency, and its service life can reach more than 20 years under normal use. In terms of safety compliance and practicality, the rated voltage of 450/750V accurately matches the electricity demand of residences: "450V" refers to the insulation voltage between the conductor and the ground/neutral wire, and "750V" is the insulation voltage between two conductors. It can not only stably carry 220V single-phase power supply but also reserve a 20%-30% safety margin to cope with voltage fluctuations when multiple devices are running simultaneously in summer, avoiding insulation breakdown. The CE certification ensures that it complies with the EU Low Voltage Directive (2014/35/EU), and indicators such as electrical safety, mechanical performance, and electromagnetic compatibility all meet the European market access standards, allowing it to be directly used in building projects exported to Europe. The cable adopts international universal color identification (red/yellow/green for live wires, blue for neutral wires, and yellow-green for ground wires), enabling electricians to quickly identify the purpose of the cable and reduce the risk of equipment burnout and electric shock caused by wrong wiring. The packaging is mostly 100m/roll, which is convenient for cutting and use during small-area wiring in home decoration and can also meet the local construction needs of small-scale building projects, avoiding material waste caused by excessively large packaging specifications. Before leaving the factory, each batch of cables undergoes multiple tests, including conductor resistance test, insulation thickness test (standard thickness 0.8-1.2mm, adjusted according to cross-sectional area, tolerance ±0.1mm), and voltage resistance test (1.5kV/1min no breakdown), ensuring stable and consistent performance and laying a solid foundation for safe electricity use in residences and buildings.
