FAQ

Questions engineers ask first

Decode the JIS C 3410 marine designation MPY.
In JIS C 3410 nomenclature, 'M' stands for Multi-core control cable (250 V), 'P' stands for +90 °C cross-linked Ethylene-Propylene rubber (EPR) core insulation, and 'Y' stands for flame-retardant Vinyl (PVC) sheath.
How do MPY, MPYC and MPYCY differ?
MPY is the unarmoured version (EP rubber cores + PVC outer sheath) for dry accommodation and bridge consoles. MPYC adds an exposed galvanised steel or tinned-copper wire braid armour ('C') over the PVC sheath for mechanical protection. MPYCY adds a second outer PVC oversheath ('Y') over the wire braid armour for bilge, deck and engine-room corrosion protection.
Why does JIS C 3410 specify both 1.25 mm² and 1.5 mm² sizes?
1.25 mm² is the traditional Japanese marine standard control cross-section under JIS C 3410, whereas 1.5 mm² aligns with IEC 60092-376 international shipboard practice. Both sizes are stocked to support newbuildings and retrofit dry-docking.
What flame-retardant standard does MPY meet?
MPY passes the IEC 60332-3-22 Category A vertical bunched wire flame test as well as IEC 60332-1-2 single-cable flame propagation requirements mandated by SOLAS and IACS classification societies.
