DSRC

What is DSRC cable?

DSRC: shipboard two-core power and lighting cable, 0.6/1 kV, silicone rubber insulation, glass yarn braids, galvanised steel wire braid. Rating: 0.6/1 kV AC, 0.9/1.5 kV DC; conductor 95 °C (silicone rubber); 1.5, 2.5 and 4 mm² (Table 20 Notes, p. 36). Standard: JIS C 3410:2010 Table 1 (p. 4) and Table 20 (p. 36); built on IEC 60092-351, -353, -354, -359 and -376 (Introduction, degree MOD).

Read in JIS C 3410:2010 (JSA English translation), seen: standard. Table 20 (p. 36): two or three cores of 1.5, 2.5 or 4 mm²; silicone rubber insulation 1.0 mm; single layer glass yarn braid 0.3 mm on each core, double layer glass yarn braid 0.55 mm over the cores; steel braid wire 0.3 mm; routine test 3 500 V. Glass yarn braids carry no letter of their own; the heat-resisting compound on them is white or black (6.8, 6.9, p. 21). Galvanised steel braid wire 0.3 or 0.4 mm (5.11.1, Table 7, p. 19), one over one under or two over two under, coverage at least 90 % (F at least 0.573, 6.16, p. 23); braid paint and protective covering white at 150/250 V and 0.6/1 kV, red at 3.6/6 and 6/10 kV, grey for fire resistant cables (6.16 c, 6.17, p. 24). Designation (cl. 10, p. 29): the symbol, a hyphen and the conductor size in mm², for multicore cables the number of cores, for telephone cables the number of pairs ("0.6/1 kV SPYC-120", "150/250 V MPYCY-12", "150/250 V TTYC-10"). FA- (flame retardant, bunched test 7.7: char at most 2.5 m) and FR- (fire resistant, mica tape under the insulation, 6.3, IEC 60331-21 or -31, 7.8) prefix the symbol.
