Open Weather Deck & Mooring Winch Feeders

The outer PVC oversheath ('Y') protects the galvanized steel wire braid ('C') from direct seawater spray, salt encrustation, and UV exposure.

Wet Bilge, Ballast & Cargo Pump Rooms

Dual PVC sheaths sandwiching the wire-braid armour allow watertight IP68 gland sealing at watertight bulkheads and deck penetrations.

Shipboard Heavy Auxiliary & Thruster Power

TPYCY and FPYCY cables deliver mechanically armoured, EMC-screened three-phase power to bow thrusters, cranes, and hydraulic power packs.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

How does DPYCY / TPYCY / FPYCY differ from DPYC / TPYC / FPYC?
While -PYC cables leave the painted wire-braid armour ('C') as the outermost layer, -PYCY cables extrude an additional protective PVC outer sheath ('Y') over the wire braid. This outer jacket prevents salt-water corrosion of the armour and enables watertight IP68 outer-sheath gland sealing.
What do all the letters in TPYCY mean?
'T' = Triple (3 cores); 'P' = Ethylene Propylene Rubber (+90 °C) core insulation; first 'Y' = PVC inner bedding sheath; 'C' = galvanized steel (or copper) wire-braid armour; second 'Y' = PVC anti-corrosion outer oversheath.
Are 5-core (5PYCY) and 6-core (6PYCY) versions part of the same JIS C 3410 family?
Yes. 2-core (DPYCY), 3-core (TPYCY), 4-core (FPYCY), 5-core (5PYCY), and 6-core (6PYCY) share identical 0.6/1 kV voltage ratings, +90 °C EPR insulation, wire-braid armour, and PVC oversheath under JIS C 3410.
What voltage and temperature ratings apply to DPYCY / TPYCY / FPYCY / 5PYCY / 6PYCY under JIS C 3410?
DPYCY / TPYCY / FPYCY / 5PYCY / 6PYCY is rated for 0.6/1 kV (maximum operating voltage 1.2 kV, dielectric test voltage 3500 V AC / 5 min (JIS C 3410)) and continuous operation from -25 °C to +90 °C (short-circuit up to +250 °C) per JIS C 3410.
