Scope

This section of BS 7870 specifies requirements for the construcion,dimensions and mechanical and electrical properties of XLPE insulated,concentric copper wire screened waveform or helical cables with solid aluminium core conductors having a rated voltage of 0.6/1(1.2)kV.It is applicable to cables that,when assessed by the specified tests,produce lower levels of smoke and corrosive gases under exposure to fire than cables conforming to BS 7870-3.11 or to BS 7870-3.40. It specifies requirements for the following types of cable: a) 3-core,3-phase,with XLPE insulaiton,a concentric neutral/earth conductor of copper wires on a synthetic bedding and a thermoplastic oversheath; b) 4-core,3-phase and a separate neutral,with XLPE insulaiton,a concentric earth conductor of copper wires on a synthetic bedding, and a thermoplastic oversheath. This section of BS 7870 is applicable to cables that are designed for a maximum continuous conductor operating temperature of 80℃ and for a maximum short circuit conductor temperature of 250℃.
