BS 7870-5:2011

LV and MV polymeric insulated cables for use by distribution and generation utilities. Polymeric insulated aerial bundled conductors (ABC) of rated voltage 0.6/1 kV for overhead distribution | Status: Confirmed, Current

1 Scope This part of BS 7870 specifies requirements for the construction, dimensions and mechanical and electrical properties of polymeric insulated aerial bundled conductors (ABCs) of rated voltage 0.6/1(1.2) kV, designed for a maximum continuous conductor operating temperature of 75 °C. This part of BS 7870 specifies requirements for ABCs with the following:

• • two, four or five-core construction;
• • phase and neutral conductors of equal size and type;
• • conductor sizes from 25 mm2 up to and including 120 mm2;
• • optional, insulated control or street lighting cores (see Annex A).

NOTE 1 The fifth core in the five-core bundle is designated as a protective conductor (protective core), i.e. a conductor used for some measure of protection against electric shock.

NOTE 2 Guidance on type approval is given in Annex B.
