BS 7870-4.10:2011+A1:2016 specifies requirements for the construction, dimensions
and mechanical and electrical properties of 6.35/11(12) kV to 19/33(36) kV
single-core cables having either aluminium or copper conductors, cross-linked
polyethylene (XLPE) or ethylene propylene rubber (EPR) extruded insulation, a
copper wire metallic screen and an oversheath of one of the following
compounds:medium density polyethylene (MDPE) compound type DMP 5 (Type A
cables);thermoplastic compound type DMZ 4 for cables with having a low emission
of smoke and corrosive gases when affected by fire (Type B cables).The standard also specifies requirements for 11 kV cables laid up in a triplex
formation.This section of BS 7870 is applicable to cables that are designed for a maximum
continuous conductor operating temperature of 90 °C and for a maximum
short-circuit conductor temperature of 250 °C.NOTE Information to be supplied by the purchaser, and items to be agreed
between the purchaser and the manufacturer at the time of enquiry and/or order
are given in Annex B. Guidance on type testing is given in Annex C.To be read in conjunction with BS 7870-1:2011,BS 7870-2:2011.Cross References:BS 3988:1970+A3:1989BS 7870-1BS 7870-2BS EN 50267-2-1BS EN 60228:2005BS EN 60332-1-2:2004BS EN 60332-3-24:2009BS EN 60811-1-2BS EN 60811-1-3BS EN 60811-2-1BS EN 61034-1BS EN 61034-2HD 603 S1HD 605 S2HD 620 S2HD 626 S1HD 627 S1IEC 60502-2Incorporates the following:Corrigendum, August 2012.
