EPR Insulated Flame Retardant Shipboard Power Cable
Our 0.6/1kV EPR Insulated Flame Retardant Shipboard 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.
Ethylene Propylene Rubber (EPR) insulation offers exceptional flexibility and excellent dielectric properties while maintaining full flame retardancy, making it the preferred choice for installations requiring superior bending performance and long-term reliability in demanding conditions. EPR provides high flexibility, ensuring reliable power transmission under demanding conditions.
Overview
1. Why EPR? A Material Choice That Matters
EPR insulation offers distinct advantages over XLPE in specific marine applications:
Property | EPR | XLPE |
Flexibility | Excellent – easier handling in tight spaces | Moderate – stiffer material |
Dielectric Properties | Outstanding | Excellent |
Low-Temperature Performance | Superior down to -40°C | Good down to -40°C |
Typical Application | Flexible installations, vibration-prone areas | Fixed installations, higher voltage ratings |
EPR is flexible, flame-retardant, and suitable for high-temperature areas, with insulation per IEC 60092-351. Our EPR insulated shipboard cables are intended for electric power, lighting and general control systems of shipboard, oil platforms and offshore buildings.
