Abstract
1 Scope This section of BS 7870 specifies requirements for the construction, dimensions and mechanical and electrical properties of concentric copper wire combined neutral/earth (CNE) service cables 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 °C and for a maximum short circuit conductor temperature of 250 °C.
