MPYCSLA

What is MPYCSLA cable?

MPYCSLA: shipboard multicore control and signal cable, 150/250 V, EPR insulation, PVC sheath, common aluminium laminated tape shield, galvanised steel wire braid. Rating: 150/250 V AC, 225/375 V DC; conductor 90 °C; 1 mm² cores, 2 to 44 cores (Table 23 Notes 3 and 4, p. 39). Standard: JIS C 3410:2010 Table 1 (p. 5) and Table 23 (p. 39); 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 23 (p. 39): 2 to 44 cores of 1 mm²; EPR insulation 0.6 mm; aluminium laminated tape about 0.05 mm over the laid-up cores; PVC sheath 1.1 to 1.8 mm; steel braid wire 0.3 mm; PVC protective covering 0.9 to 1.3 mm; routine test 1 500 V. 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. TMC prints the same name in its catalogue (manufacturer).
