What is TPYC cable?
TPYC: shipboard three-core power and lighting cable, 0.6/1 kV, EPR insulation, PVC sheath, galvanised steel wire braid. Rating: 0.6/1 kV AC, 0.9/1.5 kV DC, 1.5 to 185 mm² (Table 17, p. 33); 3.6/6 kV AC, 10 to 150 mm² (Table 35, p. 50); 6/10 kV AC, 16 to 150 mm² (Table 37, p. 52); conductor 90 °C. Standard: JIS C 3410:2010 Table 1 (p. 3) and Tables 17, 35 and 37 (pp. 33, 50, 52); 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 17 (p. 33): three cores of tinned or plain annealed stranded copper 1.5 to 185 mm²; EPR insulation 1.0 mm (up to 16 mm²) to 2.0 mm (185 mm²); PVC sheath 1.2 to 2.7 mm; steel braid wire 0.3 mm (0.4 mm from 70 mm²); PVC protective covering 0.9 to 2.0 mm; routine test 3 500 V. Table 35 (p. 50): three screened cores of 10 to 150 mm²; EPR insulation 2.5 mm; PVC sheath 1.9 to 3.0 mm; steel braid wire 0.4 mm; PVC protective covering 1.5 to 2.1 mm; routine test 12.5 kV. Table 37 (p. 52): three screened cores of 16 to 150 mm²; EPR insulation 3.4 mm; PVC sheath 2.2 to 3.1 mm; steel braid wire 0.4 mm; PVC protective covering 1.6 to 2.2 mm; routine test 21 kV. 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).

JIS C 3410 shipboard cables: how to read the cable type names
Fire behaviour (EU CPR)
PVC sheath (Y).
Typically targeted, as declared by makers for this kind of construction in the examples this site checked (not the class of this cable):
EcaN1XV-R, Ahlsell (seller)Cca-s3,d1,a3FG16OR16, Nexans (La Triveneta Cavi)EcaU1000 R2V, Nexans (La Triveneta Cavi)EcaN2XSY, Waskönig+Walter (10 kV datasheet)
Listed as sources, alphabetically by maker. No maker pays to appear here.
A CPR class is declared by the maker in its Declaration of Performance and printed on the sheath (EN 50575 cl 7). This decoder does not assign one. What the CPR classes mean →
