Product Overview
The CEPJR90/SC is a premium halogen-free, low-smoke, flame-retardant marine flexible power cable engineered for critical circuits that demand a combination of superior electrical performance, enhanced thermal sheath resistance, and maximum mechanical protection. It features Ethylene Propylene Rubber (EPR) insulation for excellent dielectric and thermal stability, a cross-linked polyolefin (SHF2) inner sheath for high-temperature endurance, and galvanized steel wire braid armor. This robust design is essential for ensuring reliability and safety in physically demanding and higher ambient temperature environments on vessels and offshore installations.

Key Performance Characteristics
-
Superior EPR Insulation: Ethylene Propylene Rubber (EPR) provides outstanding dielectric strength, excellent thermal stability across a wide temperature range, and superior resistance to moisture, heat aging, and electrical stress.
-
High-Temperature Resistant Inner Sheath: The cross-linked polyolefin (SHF2) inner sheath offers enhanced thermal endurance and deformation resistance in elevated ambient temperature environments, ensuring sheath integrity where standard thermoplastics may fail.
-
Maximum Mechanical Protection: The galvanized steel wire braid armor provides exceptional resistance to crushing, impact, abrasion, and rodent damage, protecting the cable core in exposed or hazardous routing paths.
-
Halogen-Free & Enhanced Fire Safety: Constructed with halogen-free, low-smoke materials (IEC 60754 & IEC 61034) and is flame retardant (IEC 60332). This minimizes corrosive gas emission and smoke density in fire scenarios, enhancing personnel safety.
-
High Flexibility: Despite its heavy-duty armor, the use of flexible Class 5/6 conductors ensures the cable remains manageable for installation in complex cable trays and confined spaces.
Standards & Compliance
This cable is designed and manufactured in accordance with key international marine and safety standards:
-
IEC 60092-350, 353 (General construction and armor requirements)
-
IEC 60228 (Conductors)
-
IEC 60092-360 (Insulation and sheath materials)
-
IEC 60332-1 & IEC 60332-3-22 (Flame retardancy tests)
Typical Applications
This armored flexible cable is specified for critical circuits where robust mechanical protection, electrical reliability, and performance in warmer ambient conditions are required:
-
Marine & Offshore: Power feeds and control circuits for deck machinery, engine room auxiliary systems, and equipment in higher-temperature zones on ships and offshore platforms.
-
Heavy Industry: Robust power and control wiring in industrial plants, such as metallurgy or power generation, where cables are exposed to physical stress and higher ambient temperatures.
