21、shall comply with the requirements given in HD 383 for Class 5 conductors. The wires may be plain or tinned. 2.3.2 Separator A separator of suitable materiai may be applied around each conductor. 2.3.3 Insulation , The insulation shall be rubber compound of the type Ei4 applied around each conductor

22、 The insulation shall be applied by extrusion. The insulation thickness shall comply with the specified value given in Table I, column 2 of this Part. 2.3.4 Assembly of cores The cores of the two core cables shall be laid in parallel. The distance between the centre of conductors shall comply with

23、the mean values given in Table I, columns 3 and 4 of this Part, Page 5 HD22.8 S1 - REPRINT 1992 2.3,5 Sheath The sheath shall be rubber compound of type EM2 applied around the core. The sheath shall be applied as follows:- (a) for single core cables The sheath shall be capable of being removed witho

24、ut damage to the cores. (b) for two core cables The sheath shall fill the spaces between the cores forming a filling but it shall be capable of being removed without damage to the cores. The thickness of the sheath shall comply with the specified value given in Table I, column 5 of this Part. The pr

25、eferred sheath colours are green or black. 2.3.6 Overall dimensions The mean overall dimensions shall be within the limits given in Table I, columns 6 and 7 of this Part. 2.3.7 Core identification Each core shall be identified by colour as follows:- single core cable: brown two core cable : brown an

26、d light blue Compliance with the requirements of Clause 2.3 of this Part shall be checked by inspection and by the tests given in Table II of this Part. For the requirements of Clause 2.3.4, the procedure to be followed is generally as specified in Clause 1.1 1 of Part 2 of this HD except that the m

27、easured value is the distance between the centres of the two conductors. The mean of the values obtained from the three samples shall be taken as the mean distance. 2.5 Guide to use See Appendix 1 to Part 1 of this HD. 3VOV583 0035438 4 E * Page 6 HD22.8 S1 - REPRINT Table I, General Data for TvDes
