This section of BS 7870 specifies requirements for the construction, dimensions and mechanical and electrical properties of copper wire waveform cables with solid aluminium core conductors, XLPE insulation and PVC oversheath having a rated voltage of 0.6/1(1.2) kV.
It specifies requirements for the following types of cable:
-
3-core, 3-phase, with a concentric neutral/earth conductor of copper wires bedded on a single rubber layer;
-
4-core, 3-phase and a separate neutral, with a concentric earth conductor of copper wires bedded on a single rubber layer.
This section of BS 7870 is applicable to cables that are designed for a maximum continuous conductor operating temperature of 80 °C and for a maximum short circuit conductor temperature of 250 °C.
