Product Overview
The CEPJR90/NC is a premium halogen-free, low-smoke, fire-resistant marine flexible power cable engineered for the most critical and physically demanding safety circuits, particularly in elevated ambient temperature environments. It combines superior Ethylene Propylene Rubber (EPR) insulation, a high-temperature cross-linked polyolefin (SHF2) inner sheath, and galvanized steel wire braid armor. This robust design provides certified circuit integrity during a fire, enhanced thermal sheath performance, and maximum mechanical protection for essential emergency and power systems.

Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The cable is engineered to maintain circuit integrity and continue operating for a specified duration under direct flame, a critical requirement for all life-safety and emergency circuits.
-
Halogen-Free & Low Smoke Safety: Complies with IEC 60754 (halogen-free) and IEC 61034 (low smoke density), minimizing corrosive gas emission and smoke obscuration during a fire to enhance personnel safety in confined spaces.
-
High-Temperature Resistant Inner Sheath: The cross-linked polyolefin (SHF2) inner sheath offers improved thermal endurance and deformation resistance in elevated ambient temperature environments compared to standard thermoplastic sheaths.
-
Maximum Mechanical Protection: The galvanized steel wire braid armor provides supreme resistance to crushing, impact, abrasion, and rodent damage, safeguarding the cable core in exposed or high-risk locations.
-
High Flexibility: Despite its heavy-duty armor, the use of flexible Class 5/6 conductors ensures sufficient flexibility for installation in essential cable routes and trays.

Typical Applications
This armored fire-resistant cable is specified for critical circuits in high-ambient-temperature areas where robust mechanical protection is also required:
-
Marine & Offshore: Essential power feeds and control circuits for emergency generators, fire pumps, and critical systems located in engine rooms, machinery spaces, or other warm and high-risk areas 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 both physical stress and higher ambient temperatures.
