Defines 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 degree C.

This part of BS7870 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 BS7870 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 AnnexA).

NOTE1 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.

NOTE2 Guidance on type approval is given in AnnexB.
