BS 7870-3.21:2011 LV and MV polymeric insulated cables for use by distribution and generation utilities. Specification for distribution cables of rated voltage 0.6/1 kV. XLPE insulated split concentric cables with copper or aluminium conductors
This section of BS 7870 specifies requirements for the construcion,dimensions and mechanical and electrical properties of split concentric service calbes having a rated voltage of 0.6/1(1.2)kV.
It specifies requirements for the following types of cable:
a) single phase or 3-phase;
b) stranded copper or solid aluminium conductors;
c) XLPE insulation and PVC oversheath.
This section of BS 7870 is applicable to cables that are designed for a maximum continuous conductor operating temperature of 90℃ and for a maximum short circuit conductor temperature of 250℃.
