Overview

1 What you need to know about different shipboard power cable models

Model names are just labels – construction & rated voltage are the most important
For example: Chinese marine power cable model CEV92/SA 0.6/1KV and Japanese marine power cable model FA-DPYCY 0.6/1KV have the same construction and rating – they are functionally identical.

Cable Model	CEV92/SA 0.6/1KV	FA-DPYCY 0.6/1KV
Conductor	Copper	Copper
Insulation	EPR	EPR
Inner Sheath	PVC	PVC
Armor	Galvanized Steel Wire	Galvanized Steel Wire
Outer Sheath	PVC	PVC
Rated Voltage	0.6/1KV	0.6/1KV

3 Overview of Technical Parameters

Parameter category	Range/Standard
Rated voltage	0.6/1kV, 1.8/3kV
Conductor	Tinned copper(class 2, class 5 & class 6)
Insulation	PVC, EPR, XLPE
Inner sheath	No inner sheath(lightweight design), Inner sheath(Enhance mechanical protection)
Armor	Galvanized steel wire/Tinned copper wire/No armor
Outer sheath	No outer sheath/PVC/SHF1/SHF2
Flame retardant	IEC 60332-1-2 (Single cable) / IEC 60332-3-22 Category A (Bunched cable)
Fire resistant	IEC 60331
Low-smoke zero-halogen(LSZH)	IEC 61034, IEC 60754

4 Analysis of Technical Specification

4.1 Insulation Material

PVC: Not a low-smoke zero halogen material, seldom used now.

EPR: More flexible, Suitable for applications such as deck mechanical connections where frequent exposure to mechanical stress is required.

XLPE: Excellent comprehensive performance and high cost-effectiveness.

4.2 Flame Retardant & Fire Resistant

Flame Retardant Shipboard Cable: Complies with IEC 60332-3-22 Category A, preventing the spread of fire.

Fire Resistant Shipboard Cable: Compliant with IEC 60331, essential for emergency circuits (fire pumps, escape lighting). Conductor covered by fire resistant mica tape, it ensures normal operation of cables for a certain period of time.

4.3 Low-smoke Zero-halogen(LSZH)

Cable use EPR or XLPE insulation and sheath materials are SHF1 or SHF2 are Low-smoke Zero-halogen(LSZH) cable, they usually used in passenger ships, yachts, and enclosed cabins to reduce toxic gases and smoke, compliant with IEC 61034, IEC 60754.

4.4 Flexible conductor

Class 5 or Class 6: Suitable for frequent movement and confined spaces. Smaller bending radius than Class 2 conductor.

4.5 Lightweight design(no inner sheath)

Advantage: lower weight, suitable for fixed installation scenarios with no risk of severe mechanical damage.

4.6 Armor type

Galvanized steel wire braided: resistant to tension and compression, suitable for vertical risers or buried underground.

Tinned copper wire braided: It provides both electromagnetic shielding and mechanical protection, and is commonly used in inverter power cables.

5 Standard & Compliance

5.1 Material & Core Standard

Standard	Standard name	Standard Scope of Application
IEC 60228	Conductors of insulated cables	Specified conductor structure (copper conductor, tinned copper conductor, Class 1 solid conductor, Class 2 stranded conductor, Class 5/6 flexible conductor)
IEC 60092-360	Electrical installations in ships - Part 360: Insulating and sheathing materials for shipboard and offshore units, power, control, instrumentation and telecommunication cables	Main standards for materials
IEC 60092-350	Electrical installations in ships - Part 350: Shipboard power cables - General construction and test requirements	The basic standard for shipboard cables stipulates general material, structural, and testing requirements

5.2 Performance Standard

Performance	Standard	Requirement
Single Cable Flame Retardant	IEC 60332-1-2	Passed
Bunched Cable Flame Retardant	IEC 60332-3-22	Category A
