This abstract covers copper core cables with XLPE (cross-linked polyethylene) insulation and PVC (polyvinyl chloride) sheathing. They are single-core (1X) with common specifications including 1X50mm², 1X95mm², 1X120mm², 1X300mm², and 1X400mm², with a rated voltage of 1kV, suitable for low-voltage power transmission scenarios.​ In terms of materials, the XLPE insulation layer has excellent temperature resistance (long-term operating temperature up to 90℃) and insulation performance, which can reduce power loss; the PVC sheath has good corrosion resistance and mechanical protection capabilities, adapting to various laying environments. The single-core design makes it more flexible in single-phase power transmission, especially suitable for scenarios that require separate wiring.​ In terms of specifications, 1X50-120mm² cables have moderate current-carrying capacity, suitable for building distribution branches, small motor power supply, etc.; 1X300-400mm² cables have larger current-carrying capacity and can be used in high-power scenarios such as industrial equipment main power supplies and large transformer outgoing lines. All cables meet the 1kV low-voltage transmission standards and can ensure the stability and safety of power transmission.

This article introduces 1kV cables with an Al/XLPE/PVC structure, covering a variety of single - core cross - section specifications, including 1×630mm², 1×500mm², 1×400mm², 1×300mm², 1×240mm², 1×185mm², 1×150mm², 1×120mm², 1×95mm² and 1×70mm². The structural design of this series of cables has clear functionality: Aluminum (Al) is used as the conductor, which has good conductivity and economy, making it suitable for medium and low - voltage power transmission; Cross - linked polyethylene (XLPE) serves as the insulation layer, with excellent temperature resistance and insulation performance, which can adapt to the stable operation of the 1kV voltage level; Polyvinyl chloride (PVC) is used as the sheath, which has wear - resistant and anti - corrosion properties and can protect the cable from external environmental damage. In terms of application scenarios, small - section specifications (such as 1×70mm² and 1×95mm²) are suitable for small industrial equipment and building distribution branches; Medium - sized sections (such as 1×120mm² to 1×300mm²) can meet the needs of large - scale building total power distribution and small and medium - sized motor power supply; Large sections (such as 1×400mm² and above) are applicable to high - current transmission scenarios such as industrial park main lines and substation outgoing lines. Overall, relying on its structural rationality and specification diversity, this series of cables can adapt to various power transmission needs under the 1kV voltage level.
