17、SI 12 February 2004 iii Foreword BS 7870 was prepared by Subcommittee GEL/20/2. It implements the nationally applicable parts of Harmonisation Documents HD 603, 604, 605, 620, 622, 626 and 627, published by the European Committee for Electrotechnical Standardization (CENELEC), in accordance with the
18、 decision of the CENELEC Technical Board. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. Tags indicating changes to text carry the number of the amendment. For example, text altered by amendment is indicated by !“. BS 7870 applies to cables for f
19、ixed installations having a rated voltage Uo/U up to and including 19/33 kV, and is published as a series of separate parts and sections, as listed in the table in the foreword of Part 1. This section of BS 7870 is to be read in conjunction with BS 7870-1 and BS 7870-2. This section of BS 7870 imple
20、ments Part 3E of HD 604 and HD 604 A1. The cable types included in this section are listed below: a) 3- and 4-core cables having copper conductor and steel wire armour; b) 3- and 4-core cables having solid aluminium conductors and aluminium wire or strip armour; c) single-core cables having stranded
21、 copper or stranded aluminium conductor and aluminium wire armour; d) single-core cables having solid or sectoral aluminium conductors and aluminium wire or strip armour; e) multicore auxiliary cables having from 2 up to 48 cores with copper conductors and steel wire armour. A “Guide to use” for the
22、 above cables is given in Annex A. Amendment No. 1:2004 implements the changes to the identification of cores by colours, in accordance with HD 308 S2. The principal identification colours are now: Single phase Green-and-yellow (Earth); blue (Neutral); brown (Live). Three phase Green-and-yellow (Ear
23、th); blue (Neutral); brown, black, grey (Live). Users should ensure that any interconnection between cables with these new colours and those with the pre-existing ones is carried out safely. BS 7671, as amended in parallel with this standard, gives some guidance in this respect, but does not cover a
24、ll installation conditions or cable uses. The provisions introduced by amendment No. 1:2004 are effective from 1stApril 2004. The original version of this standard remains current until 31stMarch 2006. Annex A is informative. Licensed Copy: London South Bank University, London South Bank University,
