26、7 0 000 aAWG = Closest American Wire Gage. 6 Identification and marking The identification and marking 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

27、designation (without colour information) is given in TR 6058 plus the corresponding nearest AWG (gauge 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 s

28、pots are not necessary on jacket. prEN 4681-002:2011 (E) 7 6.1 Single core For differentiation with copper cables, colour of manufacturer identification markings shall be in accordance with Table 5 for size 24 to size 4/0. Table 5 Colour of manufacturer identification markings Family Colours AD Oran

29、ge or red AZ For size 22, some dashes are positioned between adjacent manufacturer markings. For size 10 to size 4, in addition to cable manufacturer identification markings, dark spots shall be positioned all along according to the definition described in 6.2. NOTE From size 24 to size 12, dark spo

30、ts 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, in addition to cable manufacturer identification

31、markings, darks spots are positioned all along according to the definition described hereafter and in Figure 1 and Table 6. NOTE These dark spots are necessary to facilitate further manufacturing operations. Figure 1 PXL1L2DXprEN 4681-002:2011 (E) 8 Table 6 Spots dimensions Dimensions in millimetres
