适用范围：1.1 This standard covers the requirements and tests for armoured and unarmoured three, four and four core with reduced neutral conductor, PVC insulated and PVC sheathed cables with shaped solid aluminium conductors for electric supply.1.2 The cables specified in this standard are suitable for use on ac single phase or three phase (earthed or unearthed) systems for rated voltages up to and including 1 100 V. These cables may be used on dc systems for rated voltages up to and including 1 500 V to earth.Note — The cables conforming to this standard may be operated continuously at a power frequency voltage 10 percent higher than the rated voltage.1.3 The cables covered in this standard are suitable for use where the combination of ambient temperature and temperature rise due to load results in a steady conductor temperature not exceeding 70°C.
