BS 7912:2012+A1:2017

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.Cross References:BS EN 60287-1-1BS 7970:2012BS EN 60811-202:2012BS EN 60811-502:2012BS EN 60230:2002BS EN 60060-1:2010BS 7870-2:2011 BS EN 60885-3:2015BS EN 62271-209:2007BS EN 60811-503:2012BS EN 60811-508:2012BS EN 61462:2007BS EN 60811-409:2012BS EN 60811-401:2012BS EN 60811-501:2012BS EN 60229:2008IEC 60050-461:2008 Ed 2BS EN 60811-201:2012BS EN 60228:2005BS EN 60811-505:2012BS EN 60332-1-2:2004BS EN 60811-509:2012BS EN 60811-605:2012BS EN 60811-507:2012 IEC 60183:2015HD 632 S2:2008IEC 60840:2011BS EN 60099-4:2014Incorporates the following:Amendment, July 2017; Corrigendum, January 2016; Corrigendum, February 2015
