2 Core XLPE PE PVC Insulated Power Overhead Copper Aluminum Cable 10mm² 16mm² 25mm²​ The 2-core overhead power cables, available in 10mm², 16mm², and 25mm² with copper or aluminum conductors and XLPE/PE/PVC insulation, offer versatile solutions for low to medium-voltage transmission. Designed for overhead use in residential, commercial, and light industrial settings, they balance conductivity, durability, and cost-effectiveness.​ Copper conductors (100% IACS) excel in high-efficiency scenarios, while aluminum (61% IACS) provides lightweight affordability. The 10mm² suits small homes, 16mm² for medium households/shops, and 25mm² for larger loads like workshops. Insulation options cater to diverse climates: XLPE resists -40°C to 90°C and UV for harsh environments; PE offers flexibility for rural areas; PVC is budget-friendly for stable urban grids.​ With 2-core (1 phase + neutral) design, they simplify installation and reduce EMI. Compliant with IEC 60502 and ASTM, these cables ensure reliable power delivery, making them ideal for service drops, rural feeders, and industrial peripherals. Their multi 规格 and insulation choices make them a go-to for tailored overhead electrical solutions.

630mm² and 500mm² XLPE single core power cables are high-performance cables designed for medium and high voltage power transmission scenarios. The conductors can be 100% pure copper or aluminum, with cross-linked polyethylene (XLPE) as the insulation layer and PVC jacket as the outer layer. They combine excellent conductivity, temperature resistance and mechanical protection capabilities, and are widely used in substations, large industrial parks, high-rise building distribution trunk lines and other scenarios requiring large-capacity power transmission.​ In terms of specification parameters, both cables cover medium and high voltage levels such as 10kV, 20kV and 35kV to meet the power transmission needs of different voltage levels. The 500mm² cable has a current-carrying capacity of about 650-750A when laid in the air, and about 550-650A when laid underground due to different heat dissipation conditions; the 630mm² cable has better current-carrying capacity, reaching 780-880A in the air and 680-780A underground, which can be adapted to large-capacity power transmission links such as large transformer outgoing lines and high-voltage switchgear connections. The conductor is made of high-purity materials. The purity of copper conductor is ≥99.95%, and the DC resistance at 20℃ is ≤0.0308Ω/km. The purity of aluminum conductor is ≥99.5%, and the resistance is ≤0.0501Ω/km, all passing strict conductivity tests. The XLPE insulation layer forms a three-dimensional network structure after cross-linking treatment, with a temperature resistance range of -40℃ to 90℃, and can withstand 130℃ in short-term overload. The insulation resistance is ≥1000MΩ·km, and the dielectric loss tangent value is ≤0.003 (20℃), ensuring insulation stability under high voltage. The PVC sheath has a thickness of 2.5-4.0mm, with UV resistance and acid-alkali corrosion resistance. The sheath is mainly black, with specifications, voltage, certification and other marks printed on the surface.​ In terms of characteristic applications, 500mm² cables are suitable for incoming and outgoing lines of medium-sized substations and main transmission lines in industrial parks, and can be connected to transformers with a capacity of less than 5000kVA; 630mm² cables are suitable for large-capacity scenarios such as large substations and thermal power plants, and can carry power output of transformers with 8000kVA and above. The single core structure design is convenient for laying in dense cable trenches or bridges, with a bending radius of not less than 12 times the outer diameter, which can adapt to complex wiring environments. In high-rise buildings, both cables can be used as distribution trunk lines to transmit power from the bottom distribution room to high floors. Their flame-retardant PVC sheaths (optional) can meet fire protection requirements and delay flame spread. In addition, the aluminum conductor version has the advantages of light weight (about 1/3 of copper) and low cost, so it is more economical in long-distance power transmission projects, while the copper conductor version, with high conductivity (about 1.6 times that of aluminum), is mostly used in scenarios with strict requirements on transmission efficiency.​ In terms of material technology, copper/aluminum conductors are subjected to continuous extrusion and annealing treatment. Copper conductors adopt compact stranding technology, and aluminum conductors are drawn and bunch stranded to improve conductor density and mechanical strength. The XLPE insulation layer is extruded through a dry cross-linking process, and cross-linking is completed at 180-200℃ and 0.5-1.0MPa to ensure no bubbles or impurities in the insulation layer. The PVC sheath is wrapped around the insulation layer by co-extrusion process, closely attached to the insulation layer to enhance the overall structural stability. The finished cable must pass strict tests such as power frequency withstand voltage test (35kV cable applies 95kV/1min without breakdown) and partial discharge test (≤10pC), meeting international standards such as GB/T 12706 and IEC 60502.​ During installation and maintenance, the cable supports direct burial, pipe threading, tunnel laying and other methods. Special transition joints must be used for copper-aluminum conductor connection to prevent electrochemical corrosion. In daily use, excessive bending or mechanical impact should be avoided, and insulation resistance and sheath integrity should be tested regularly. The product warranty period is 1-2 years. During the period, faults caused by material or process defects can be replaced free of charge, and the manufacturer provides technical support and on-site installation guidance services.
