This cable is an XLPE-insulated 4-core aluminum conductor power cable with specifications of 4×240mm² + 1×400mm², suitable for underground laying and rated voltage of 0.6/1kV. It offers excellent insulation and voltage resistance, making it ideal for medium-low voltage power distribution systems.

This is a low-voltage underground power cable (RVFV/ARVFV type) with 4-core 25 sq. mm stranded aluminum conductors and XLPE (cross-linked polyethylene) insulation, rated for 1000V. Designed for fixed underground installation, it offers flexibility and corrosion resistance, making it ideal for industrial, construction, and municipal power distribution systems.

This article introduces Cable SDI XLPE Aluminium Al (aluminium SDI cross - linked polyethylene cable), which covers 10 single - core cross - section specifications such as 1×70mm², 1×95mm², 1×120mm², 1×150mm², 1×185mm², 1×240mm², 1×300mm², 1×400mm², 1×500mm², and 1×630mm², and is suitable for diverse power transmission scenarios.​ This series of cables has significant advantages in performance: The aluminium (Al) conductor has both good conductivity and cost - effectiveness, suitable for medium and low - voltage power transmission; The XLPE (cross - linked polyethylene) insulation layer has strong temperature resistance, which can maintain stable insulation performance in high - temperature environments and reduce the risk of electric leakage. The single - core design flexibly adapts to different laying needs and can be flexibly combined according to the actual power supply mode.​ In terms of application, small cross - sections (1×70mm² - 1×150mm²) are suitable for small - sized equipment power supply and branch lines; medium cross - sections (1×185mm² - 1×300mm²) can meet the needs of industrial equipment main lines and medium - sized building power distribution; large cross - sections (1×400mm² - 1×630mm²) are suitable for high - voltage and high - load scenarios such as large factory main lines and regional transmission trunk lines, with wide overall adaptability.
