Product Overview
The CEPJR85/SC is a premium halogen-free, low-smoke, flame-retardant marine flexible power cable engineered for the highest performance in demanding applications. It combines superior Ethylene Propylene Rubber (EPR) insulation with a fully cross-linked polyolefin (SHF2) dual-sheath system and tinned copper wire braid armor. This construction delivers exceptional electrical reliability, enhanced thermal endurance for the sheath, effective EMI shielding, and robust protection, making it ideal for critical circuits in high-ambient-temperature and sensitive environments.

Key Performance Characteristics
-
Superior EPR Insulation: Ethylene Propylene Rubber (EPR) provides outstanding dielectric properties, excellent thermal stability, and high flexibility, ensuring reliable power transmission under demanding conditions.
-
Enhanced High-Temperature Sheath System: Features a complete dual-sheath (inner and outer) made of cross-linked polyolefin (SHF2). This material offers superior thermal endurance and deformation resistance in elevated ambient temperature environments.
-
Halogen-Free Enhanced Safety: The cable is constructed with halogen-free, low-smoke materials (IEC 60754 & IEC 61034) and is flame retardant (IEC 60332), minimizing corrosive gas and smoke emission for enhanced personnel safety.
-
Effective EMI Shielding & Durability: The tinned copper wire braid armor provides reliable electromagnetic interference (EMI) shielding. The tough, cross-linked outer sheath adds an extra layer of mechanical and environmental protection.
Standards & Compliance
This cable is designed and manufactured in accordance with key international marine and safety standards:
-
IEC 60092-350, 353 (General construction and tests)
-
IEC 60228 (Conductors)
-
IEC 60092-360 (Insulation and sheath materials)
-
IEC 60332-1 & IEC 60332-3-22 (Flame retardancy tests)
Typical Applications
This cable is suited for critical installations requiring a combination of high electrical performance, thermal sheath resistance, and EMI protection:
-
Marine & Offshore: Internal wiring for control panels, switchboards, and instrumentation in engine rooms or other higher-temperature areas on ships and offshore platforms.
-
Industrial: Flexible power and control connections in industrial settings where enhanced fire safety, EMI shielding, and performance in warmer environments are required.
