Copper core power cables with various conductor sections, equipped with PVC, PE, and PUR jackets, are core wires designed to meet diverse power transmission needs in the construction field. The conductors are made of high-purity copper (purity ≥99.95%) and cover multiple cross-sectional specifications (such as 10mm², 25mm², 50mm², 120mm², etc.), adapting to full scenarios from low-voltage lighting to medium-high voltage power transmission. Widely used in power distribution systems of residential buildings, commercial complexes, industrial plants, and public buildings, these cables ensure safe and efficient operation of building electrical systems with their excellent performance.​ Conductor and cross-sectional design are core advantages of this series. The copper core, with a conductivity of ≥58MS/m, minimizes resistance loss, reducing energy waste during power transmission. Multiple cross-sectional specifications cater to different load requirements: small sections (10-35mm²) are suitable for branch lines of lighting and sockets, meeting electricity needs of daily appliances and office equipment; medium sections (50-120mm²) adapt to trunk lines of medium-power devices like air conditioners and elevators; large sections (150-400mm²) are used for main incoming lines of buildings or power transmission of large industrial equipment, ensuring stable power supply in high-load scenarios. The gradient design of cross-sections allows cables to precisely match power demands in different building areas, avoiding issues of "overcapacity" or overload.​ Differentiated characteristics of jacket materials endow cables with strong environmental adaptability. PVC jackets, cost-effective with good flame retardancy (oxygen index ≥30) and acid-alkali resistance, are suitable for dry, normal-temperature indoor exposed or piped scenarios, such as residential wall wiring and office ceiling lines. PE jackets excel in low-temperature resistance (remaining flexible at -40℃), high impact resistance, and water/moisture proofing, ideal for humid environments (e.g., bathrooms, underground garages) or outdoor shallow burial. PUR jackets, with outstanding wear resistance, oil resistance, and anti-aging properties, withstand mechanical friction, oil erosion, and UV radiation, making them suitable for harsh scenarios like equipment connection lines in industrial plants and temporary cables at construction sites. All three jackets pass RoHS certification, releasing no harmful substances, meeting green building requirements.​ In construction scenario adaptability, the series performs comprehensively. In residential projects, small-section PVC-jacketed cables can be concealed in walls or floors, balancing safety and aesthetics. Medium-section PE-jacketed cables are used for high-floor power distribution in commercial complexes, ensuring long-term stable operation in humid environments. Large-section PUR-jacketed cables support production line power transmission in industrial plants, resisting equipment vibration and oil erosion. Additionally, the cables’ flexibility facilitates bending and threading in narrow spaces (e.g., cable trays, pipe shafts), simplifying construction. Standardized color coding (black, gray, etc.) of jackets helps distinguish phase, neutral, and ground wires during installation, reducing operational errors.​ Safety performance is integrated into product design: conductor stranding enhances mechanical strength, preventing bending fractures; jackets with high flame retardancy (UL94 V-0) slow flame spread, reducing fire risks; insulation layers (e.g., XLPE or PVC) with temperature resistance (90-105℃) prevent aging during overload. The entire series passes voltage withstand tests (≥3kV/5min without breakdown) and insulation resistance tests (≥1000MΩ), complying with national standards like GB/T 12706, securing safe operation of building power systems.​ In summary, copper core power cables with various conductor sections and PVC/PE/PUR jackets, relying on efficient conductivity, flexible cross-sectional adaptation, environmental resistance of jackets, and comprehensive safety guarantees, are ideal for full-scenario power transmission in construction, providing reliable power support for intelligent and green development of modern buildings.
