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.
