Application fit

Is MPYC right for your machine?

MPYC features an exposed galvanised steel wire braid (with anti-corrosion paint) or tinned-copper wire braid directly over the vinyl sheath, providing rugged mechanical and rodent protection in dry machinery spaces and shipboard cableways.

Fixed installation

Suitable

Shipboard machinery spaces, steering gear rooms, bulkhead penetrations and steel ladder racks.

VFD inverter to AC motor screened feeder

With conditions

Wire braid provides mechanical and low-frequency earth screening; for wet bilges or oily decks, select oversheathed MPYCY.

Use MPYCY Oversheathed

Trailing & towing

Not suitable

Fixed shipboard installation cable; not designed for dynamic trailing duty.

Use MPYCY Oversheathed

Energy chain / drag chain

Not suitable

Not intended for drag chains; for EMI-critical analog circuits, select overall-screened MPYCS/MPYCYS.

FAQ

Questions engineers ask first

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

What does the 'C' in MPYC represent?
In JIS C 3410 nomenclature, 'C' stands for braided wire armour (galvanised steel wire braid coated with anti-corrosive paint, or tinned-copper wire braid for non-magnetic zones) applied over the vinyl sheath ('Y') and +90 °C EP-rubber insulated cores ('P').
When is MPYC preferred over MPYCY?
MPYC has an exposed painted wire braid outer layer with no outer plastic oversheath, making it slightly smaller in diameter and classic in Japanese shipyards for dry internal machinery spaces where cables are clamped directly to steel cable ladders and painted after installation. Where salt water, bilge oil or deck washdown is present, choose PVC-oversheathed MPYCY.
Why is copper wire braid specified near a vessel's magnetic compass?
Ferromagnetic steel wire armour can deflect a vessel's magnetic compass when routed within the safe distance zone on the bridge deck. Ordering MPYC with a non-magnetic tinned-copper wire braid eliminates magnetic deviation.
How are cores identified inside MPYC?
Each +90 °C EP-rubber core is printed with clear sequential numbers (1, 2, 3… up to 37) for unambiguous terminal block wiring.
