FAQ

Questions engineers ask first

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

What does the 'C' at the end of DPYC / TPYC / FPYC indicate?
In JIS C 3410, 'C' denotes a metallic wire braid armour (standardly galvanized steel wire braid coated with anti-corrosive paint, or copper alloy braid for non-magnetic zones) applied directly over the 'Y' PVC sheath.
Should I select TPYC or TPYCY for wet bilges and open weather decks?
TPYC has an exposed painted wire braid on the outside, making it ideal for dry interior machinery spaces and cable trays. For open weather decks, wet bilges, or corrosive chemical spaces, choose TPYCY, which adds an extra protective PVC outer sheath ('Y') over the wire braid.
Which marine classification societies accept JIS C 3410 -PYC cables?
JIS C 3410 shipboard cables are recognized and type-approved across major IACS classification societies including ClassNK (Nippon Kaiji Kyokai), ABS, DNV, Lloyd's Register (LR), BV, and KR.
What voltage and temperature ratings apply to DPYC / TPYC / FPYC / 5PYC / 6PYC under JIS C 3410?
DPYC / TPYC / FPYC / 5PYC / 6PYC 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.
