Is MPYS / MPYCS / MPYCYS right for your machine?

The JIS C 3410 `MPYS / MPYCS / MPYCYS` series adds a dedicated overall electrostatic screen (`S`) over the cabled +90 °C EP-rubber cores to shield shipboard governor controls, bridge telemetry, tachometer signals and PLC inputs from propulsion drive and radar interference.

Fixed installation

Suitable

Shipboard automation, engine governor telemetry, bridge alarm panels and tank-level instrumentation.

VFD inverter to AC motor screened feeder

Suitable

Dedicated overall electrostatic screen ('S') isolates control signals from marine propulsion VFD harmonics.

Trailing & towing

FAQ

Questions engineers ask first

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

How do MPYS, MPYCS and MPYCYS differ from standard MPY, MPYC and MPYCY?
The trailing 'S' designates an overall (collective) electrostatic copper/Al-foil screen applied directly around the cabled EP-rubber cores beneath the PVC inner sheath. In MPYCS and MPYCYS, this inner screen ('S') is electrically isolated from the outer mechanical wire braid armour ('C'), allowing instrument engineers to earth the signal screen at a single clean reference point while bonding the armour to the ship's hull.
What is the difference between MPYS/MPYCYS (without hyphen) and MPY-S/MPYCY-S (with hyphen)?
In JIS C 3410 shipboard cable notation, 'S' without a hyphen (MPYS, MPYCS, MPYCYS) denotes an overall collective screen around the entire core bundle. '-S' with a hyphen (MPY-S, MPYC-S, MPYCY-S) denotes individual electrostatic screens applied to each pair or core inside the bundle.
Which variant — MPYS, MPYCS or MPYCYS — should I specify?
Choose MPYS for dry internal bridge consoles and control cabinets; choose MPYCS for dry machinery spaces where painted steel/copper wire braid is standard; choose MPYCYS for engine rooms, pump rooms and open decks requiring a watertight PVC outer oversheath over the braid.
Are dimensional tables shown for MPYCYS?
Yes. The reference diameter and weight table shows the full-specification MPYCYS (overall screen + inner sheath + wire braid armour + outer oversheath); unarmoured MPYS is ~3.5 mm smaller in OD.
