1. Product-Specific Information
1.1 Specification Parameters
The H07bz1-K 1×1.5mm² cable is engineered with precise specifications to ensure consistent performance in low-voltage electrical systems. At its core, the cable features a single conductor with a cross-sectional area of 1.5mm², a dimension carefully chosen to balance current-carrying capacity and
Flexibility. The conductor is typically made from high-purity copper, known for its excellent electrical conductivity, which minimizes energy loss during power transmission. Copper’s malleability also contributes to the cable’s ease of handling during installation, allowing it to be bent or routed through tight spaces without compromising structural integrity.
The insulation layer is constructed from cross-linked polyethylene (XLPE), a material that undergoes a chemical or radiation-induced cross-linking process to enhance its thermal and mechanical properties. This cross-linking transforms the linear polymer structure into a three-dimensional network, enabling the insulation to withstand higher temperatures compared to standard polyethylene. The XLPE insulation in the H07bz1-K cable can operate continuously at temperatures up to 90°C, with short-term overload capabilities reaching 130°C, making it suitable for environments where occasional temperature spikes may occur.
In terms of voltage rating, the cable is designed for 450/750V systems. The first number (450V) refers to the phase-to-earth voltage, while the second (750V) denotes the phase-to-phase voltage, ensuring compatibility with most low-voltage applications in residential, commercial, and light industrial settings. The overall diameter of the cable, including the insulation and outer sheath, is optimized to balance protection and flexibility, typically measuring around 4-6mm depending on manufacturing tolerances.
Mechanical specifications further highlight the cable’s durability. It exhibits a minimum bending radius of 4 times its outer diameter for fixed installations and 6 times for dynamic applications, ensuring it can be installed in confined spaces without damaging the insulation or conductor. The cable also boasts high tensile strength, withstanding forces up to 150N, which prevents breakage during pulling or installation.
1.2 Material and Construction
The choice of materials in the H07bz1-K cable is critical to its performance, safety, and environmental compatibility. The conductor, as mentioned, is high-purity electrolytic copper, which undergoes rigorous refining to reduce impurities that could hinder conductivity. The copper is drawn into a solid or
Stranded Wire; in many cases,
Stranded Conductors are used to enhance flexibility, making the cable easier to maneuver around corners or through conduit.
The XLPE insulation is the next key component, offering superior electrical insulation properties. Its high dielectric strength (typically above 20kV/mm) ensures that the cable can prevent electrical leakage even under high voltage stress. Additionally, XLPE is resistant to oxidation, moisture, and chemical attack, making it suitable for use in harsh environments where exposure to oils, greases, or mild chemicals is possible. This resistance to degradation extends the cable’s service life, often exceeding 25 years under normal operating conditions.
The outer sheath of the H07bz1-K cable is formulated to meet halogen-free low-smoke zero-halogen (LSZH) standards. LSZH materials are composed of polymers (such as polyethylene or polypropylene) blended with non-halogenated flame retardants, such as aluminum hydroxide or magnesium hydroxide. Unlike traditional
PVC Sheaths, which release toxic hydrogen chloride gas when burned, LSZH sheaths produce minimal smoke and non-toxic fumes, significantly improving safety in fire emergencies. The sheath also provides mechanical protection against abrasion, impact, and UV radiation, ensuring the cable remains intact in both indoor and outdoor installations, though prolonged exposure to direct sunlight may require additional protection.
The construction process of the H07bz1-K cable involves several 精密 stages. First, the
Copper Conductor is drawn to the required diameter and stranded if necessary. Next, the XLPE insulation is extruded over the conductor using specialized machinery that ensures uniform thickness and adhesion. The cross-linking process then takes place, either through steam curing (for chemical cross-linking) or electron beam irradiation (for radiation cross-linking), depending on the manufacturer’s technology. Finally, the LSZH sheath is extruded over the
Insulated Conductor, with strict quality controls in place to ensure the sheath adheres properly and meets thickness specifications.
1.3 Unique Features and Applications
One of the most distinctive features of the H07bz1-K cable is its halogen-free low-smoke flame-retardant properties, which set it apart from conventional cables. In the event of a fire, the cable’s LSZH sheath releases less than 50% of the smoke produced by
PVC Cables, as measured by smoke density tests according to IEC 61034. This low smoke emission improves visibility, allowing for safer evacuation and easier firefighting. Moreover, the absence of halogens means that the fumes generated are non-corrosive, reducing damage to electrical equipment, structural materials, and human health.
The cable’s flame-retardant performance is certified to meet international standards such as IEC 60332-1-2, which tests vertical flame propagation. It can resist ignition and prevent flame spread, making it ideal for use in enclosed spaces like apartment buildings, hospitals, and office complexes where fire safety is paramount.
Another key feature is its resistance to environmental factors. The XLPE insulation and LSZH sheath make the cable resistant to water, moisture, and 霉菌 growth, suitable for damp environments such as basements, bathrooms, and outdoor installations under protective casing. It also exhibits good resistance to temperature fluctuations, maintaining performance in both cold climates (down to -30°C) and moderate heat, ensuring reliability in diverse geographical regions.
In terms of applications, the H07bz1-K 1×1.5mm² cable is highly versatile. Its primary use is in low-voltage power distribution systems, including:
Residential wiring: Connecting lighting fixtures, power outlets, and small appliances in homes, where safety and low smoke emission are critical.
Commercial buildings: Wiring for office equipment, retail displays, and HVAC systems in malls, hotels, and business centers.
Public facilities: Hospitals, schools, and airports, where fire safety regulations are stringent and the need to minimize smoke and toxic fumes is essential.
Industrial settings: Powering control systems, auxiliary equipment, and low-power machinery in factories, where resistance to oils and chemicals is beneficial.
1.4 Manufacturing Process
The production of the H07bz1-K cable adheres to strict quality standards to ensure consistency and reliability. The process begins with raw material inspection, where
Copper Conductors, XLPE resin, and LSZH sheath compounds are tested for purity, mechanical properties, and compliance with relevant standards (such as IEC 60228 for conductors and IEC 60502 for
Power Cables).
Conductor preparation involves drawing copper rods into wires of the required diameter using a series of dies. For
Stranded Conductors, multiple wires are twisted together to form a
Flexible Core, with the stranding pattern optimized to ensure uniform current distribution and mechanical strength.
Insulation extrusion is a critical step, performed using high-precision extruders that melt the XLPE resin and apply it evenly around the conductor. The extrusion process is monitored for temperature, pressure, and speed to ensure the insulation thickness meets specifications, typically within a tolerance of ±0.1mm. After extrusion, the insulated conductor undergoes cross-linking. In chemical cross-linking, the cable is passed through a curing tube where heat and pressure activate cross-linking agents in the XLPE, forming the three-dimensional polymer network. In radiation cross-linking, electron beams penetrate the insulation, initiating cross-linking without the need for chemical additives, resulting in a more environmentally friendly process.
Following cross-linking, the cable is cooled to stabilize the insulation, then undergoes testing for electrical properties such as insulation resistance and dielectric strength. The LSZH sheath is then extruded over the insulated conductor using a second extruder, with similar precision controls to ensure uniform coverage and adhesion.
Final quality checks include dimensional measurements, mechanical tests (tensile strength, elongation at break), flame-retardant and smoke emission tests, and electrical performance tests (voltage withstand, conductor resistance). Cables that pass all tests are spooled onto reels of varying sizes (typically 100m, 250m, or 500m) for distribution.
2. General Product Information
2.1 Packaging
The H07bz1-K cable is packaged to ensure protection during storage, transportation, and handling. The primary packaging consists of sturdy wooden or plastic reels, which prevent the cable from tangling and protect it from mechanical damage. The reels are designed with flanges of sufficient height to contain the cable, and the core diameter is sized to avoid excessive bending of the cable during unspooling.
For smaller quantities, the cable may be packaged in coils wrapped in moisture-resistant plastic film, which provides a barrier against dust and humidity. Each reel or coil is labeled with essential information, including the product code (H07bz1-K), conductor size (1×1.5mm²), voltage rating (450/750V), length, batch number, manufacturing date, and compliance certifications (such as CE, UL, or IEC marks). This labeling ensures traceability and helps customers verify the product’s specifications.
Large shipments of multiple reels are often palletized, with reels secured to wooden pallets using straps to prevent movement during transportation. Pallets are then wrapped in stretch film to protect against moisture and dust, and each pallet is labeled with the total number of reels, total length, and destination information.
2.2 Transportation and Handling
Transporting the H07bz1-K cable requires adherence to best practices to maintain its integrity. The cable is classified as a non-hazardous material for transportation, but proper handling is still essential. During loading and unloading, reels should be lifted using appropriate equipment (such as forklifts or cranes) with slings placed around the reel core to avoid damaging the flanges or the cable itself. Reels should never be dropped, as this can cause internal damage to the conductor or insulation.
When transporting by road, rail, or sea, reels must be secured to prevent rolling or shifting. For sea transport, containers should be ventilated to prevent condensation, which could lead to moisture absorption by the cable. Extreme temperatures during transportation should be avoided; the cable should not be exposed to temperatures below -30°C or above 50°C for extended periods, as this can affect the flexibility of the sheath and insulation.
Upon arrival at the destination, the cable should be stored in a dry, well-ventilated area away from direct sunlight, heat sources, and chemicals. Reels should be stored horizontally on racks or pallets, not stacked vertically, to prevent deformation. Before installation, the cable should be allowed to acclimatize to the ambient temperature for at least 24 hours if it has been exposed to extreme cold, as this restores its flexibility and prevents cracking during handling.
