適用范圍：1.1 This standard covers the requirements for aluminium sheathed cables with powdered-mineral insulation and aluminium conductors, with or without a PVC covering over the aluminium sheath. Two grades, namely, 250/440 V and 650/1 100 V cables, are covered.1.2 The 250/440 V grade cables are suitable for use on single-phase or three-phase systems where the voltage between each conductor and earth does not exceed 250 V (that is, solidly earthed 440 V systems).1.3 The 650/1100 V grade cables are suitable for use on medium voltage three-phase systems where the voltage between the conductor and earth does not exceed 650 V (that is, solidly earthed 1 100 V systems). These can also be used on single-phase systems in special conditions where greater degree of safety is required.
