What is FPYCY cable?

FPYCY: shipboard four-core power and lighting cable, 0.6/1 kV, EPR insulation, PVC sheath, galvanised steel wire braid, PVC covering. Rating: 0.6/1 kV; conductor 90 C (TMC p.6, p.10, p.12). Standard: TMC catalogue name (TMC cites JIS C 3410(2010)); not a type of JIS C 3410:2010 Table 1.

Not in JIS C 3410:2010 Table 1 (pp. 2 to 8): TMC's own variant, so its values stay at seen level manufacturer. JIS Table 2 (p. 8) has F for four cores, but Table 1 lists no four or more core PY cable for power. Name printed in the TMC index p.4 ('(FA-) FPYCY'). TMC 'Marine & Shipboard Cable, JIS C 3410(2010) / IEC 60092-350, 353, 354, 376' (manufacturer), p.4 'Code Designation': FA- flame retardant, FR- fire resistance, FR-FA-, S / D / T / F single to four cores for power and lighting, M multi core for control and signal, TT telephone and instrumentation; material letters, column alignment checked on a rendered image of p.4: insulation P EP rubber, Y PVC, C XLPE; sheath Y PVC; armouring C steel wire, CB copper alloy wire; protective covering Y PVC; others SLA common shield (AL/PS tape), -SLA individual shield (AL/PS tape), -S individual shield (copper braid), E earth wire, (C) cold type (not read here). Notes: telephone cables omit the insulation letter; CB for a copper alloy braid (0.6/1KV SPYCB, SPYCBY); E suffixed for an earth wire (0.6/1kV TPYE). Pp.6, 10, 12: stranded tinned annealed copper, EPR and PVC to JIS C 3410(2010), braid coverage min. 90 %, conductor 90 C, IEC 60332-1 (FA-: IEC 60332-3 Cat. A).

Fire behaviour (EU CPR)

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 →

FPYCY as the cable designer builds it, 4x16 0.6/1 kV

Overall diameter 27.9 mm, about 1,800 kg/km. Nominal values from the standard's tables for this size, computed, not a maker's data.

FPYCY on a drum

The smallest drum that passes every check, for 27.9 mm and about 1,800 kg/km as the cable designer builds it. Drums as their makers print them; lengths are estimates: whole layers wound nested (each turn in the groove of the layer below), wound diameter 1.05 × OD, 50 mm freeboard under the flange rim. Cable makers' own tables print less, as they count aligned layers.

LengthDrum size (its makers)LayersGross weight
500 mKTG 12 (1250 mm flange), wood KTG drums (Europe), Bayka, KTG9 of 101,044–1,065 kg
1,000 mKTG 16 (1600 mm flange), wood KTG drums (Europe), Bayka, KTG11 of 132,076–2,109 kg

Barrel at least 15 × OD = 418 mm for a cable of this kind (Low voltage, multi-core): KTG table, the cable's datasheet wins. A load rating is the drum maker's own.
