35、ng of cables by the manufacturer shall be in accordance with ISO 2574 and this standard. As the designation, required for orders, is generally too long for use in electrical drawings, a shorter cross designation (without colour information) is given in TR 6058 plus the corresponding nearest AWG (gau

36、ge code). To facilitate further manufacturing operations and differentiate these aluminium cables from copper cables, markings are necessary on both core(s) and jacket (when there is a jacket). Dark spots are not necessary on jacket. BS EN 4681-002:2012EN 4681-002:2012 (E) 8 6.1 Single core For diff

38、markings. NOTE From size 24 to size 12, dark spots will be added during markings applied by the users. 6.2 Multicore For differentiation with copper cables, colour of manufacturer identification markings shall be in accordance with Table 4 for core size 24 to size 4/0. From core size 24 to size 4, i

39、n addition to cable manufacturer identification markings, darks spots are positioned all along according to the definition described hereafter and in Figure 1 and Table 6.
