EPR Insulated Flame Retardant Shipboard Flexible Power Cable

Our 0.6/1kV EPR Insulated Flame Retardant Shipboard Flexible Power Cables are designed for power transmission, lighting, and general control applications on marine vessels, offshore platforms, and industrial facilities including metallurgical plants, chemical works, and power stations.

Featuring Class 5 flexible tinned copper conductors combined with EPR (Ethylene Propylene Rubber) insulation, these cables provide exceptional flexibility for installations requiring frequent bending, tight routing, and easy handling in confined spaces.

2. EPR vs. XLPE: Why Flexibility Matters

Property	EPR	XLPE
Flexibility	Excellent – 40% lower bending force vs. XLPE	Moderate – stiffer material
Moisture Resistance	Superior – 30% better moisture barrier vs. XLPE-; insulation resistance drop <10% in humid environments	Good
Chemical Resistance	Excellent resistance to oil, solvents, and seawater	Moderate
Low-Temperature Performance	Superior down to -45°C	Good down to -40°C
Bending Radius	≥4D (D: cable diameter) – suitable for tight spaces	≥6D
Typical Application	Flexible installations, vibration-prone areas, confined cable trays	Fixed installations

EPR insulation provides 40% better flexibility than XLPE, enabling easier routing in confined shipboard spaces.

3. Class 5 Flexible Conductor Advantage

IEC 60228 Class 5 conductors use fine-stranded tinned copper wires, offering:

Feature	Benefit
Fine-stranded construction	Exceptional bending capability – ideal for cable trays, conduits, and tight spaces
Tinned copper	Superior corrosion resistance in marine saltwater environments
Easy handling	Reduced installation time and labor costs
Vibration resistance	Reliable performance in engine rooms and machinery spaces

4. Flame Retardancy Performance

Our EPR flexible cables meet IEC 60332-3-22 Category A flame retardancy requirements:

Test duration: 40 minutes of flame application

Flame temperature: 750°C

Pass criteria: Carbonization height does not exceed 2.5m

This ensures the cable will not propagate fire along its length in bunched installations.

5. Why Choose Our EPR Flexible Cables?

Superior Flexibility – Class 5 fine-stranded conductors provide exceptional bending performance, reducing installation time and complexity in tight spaces. EPR insulation further enhances flexibility compared to XLPE.

High Safety – Low smoke, zero halogen, Category A flame retardant – minimizes toxic fumes and maintains visibility during fire emergencies.

Durable Marine Construction – Tinned copper conductor resists corrosion in saltwater environments; EPR insulation provides excellent moisture and chemical resistance.

Material Flexibility – Choose between SHF1 (thermoplastic, economical) and SHF2 (thermoset, high oil/UV resistance) sheaths based on environmental requirements.

Wide Application Range – Suitable for interior cable trays, control panels, engine rooms, decks, and offshore platforms.

International Compliance – Manufactured to IEC standards (IEC 60092-350, -351, -353, -360, IEC 60332-3-22, IEC 60754, IEC 61034) for global marine and offshore projects.
