Full Description

BS 7912:2012+A1:2017 specifies tests and requirements for power cables with XLPE insulationand metal sheath and their accessories for rated voltages from 66 kV (U_m = 72.5 kV) to 132 kV(U_m = 145 kV) for fixed installations.

NOTE 1 Cable systems to this standard do not normally have high electrical stresses at the conductor or insulationscreen. If the calculated nominal electrical stresses at the conductor screen will be higher than 8.0 kV/mm and/or atthe insulation screen higher than 4.0 kV/mm, then attention is drawn to the need to conduct a prequalification test in accordance with IEC 60840:2011, Clause 13.

This British Standard is applicable to single-core cables and three-core cables with separate cores andto their accessories for usual conditions of installation and operation. It is not applicable to specialcables and their accessories, such as those designed for submarine cables, for which modification tothe standard tests might be necessary or special test conditions might need to be devised.

NOTE 2 Annex A gives tests and requirements for cable bonding leads. Annex B gives tests and requirements for sheath voltage limiters (SVLs), while Annex C gives tests and requirements for link housings. Annex D gives an additional water blocking test for phase conductors.
