Product Overview
The CJPJR/NC is a premium, unarmored marine flexible power cable designed to provide the highest level of fire safety and thermal performance for critical circuits in protected, high-ambient-temperature environments. It combines a certified fire-resistant mica glass tape and XLPE insulation core with a halogen-free, low-smoke, cross-linked polyolefin (SHF2) sheath. This cable is engineered to maintain circuit integrity during a fire while offering enhanced durability in warmer conditions, making it an essential choice for vital emergency systems where flexibility and weight savings are also key.

Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The core construction is designed to maintain circuit integrity and continue operating for a specified period under direct flame exposure, which is critical for all emergency and life-safety systems.
-
Enhanced High-Temperature Sheath: The sheath is made from cross-linked polyolefin (SHF2), providing superior thermal stability, deformation resistance, and longevity in elevated ambient temperature environments compared to standard thermoplastic (SHF1) sheaths.
-
Comprehensive Fire Safety Suite: Integrates multiple top-tier safety standards: Fire Resistance (IEC 60331), Flame Retardancy (IEC 60332), zero halogen emission (IEC 60754), and low smoke density (IEC 61034). This combination maximizes personnel safety by limiting fire spread, toxic fumes, and smoke.
-
Superior Flexibility & Light Weight: As an unarmored cable, it offers excellent flexibility and is lightweight, facilitating easier and faster installation in complex cable trays, conduits, and control panels within protected enclosures.

Typical Applications
This cable is specifically designed for critical circuits within protected spaces where fire survival and performance in warmer environments are mandatory:
-
Marine & Offshore: Essential emergency circuits such as emergency lighting, alarm and detection systems, and control wiring located in engine control rooms, machinery spaces, or other areas with higher ambient temperatures on ships and offshore platforms.
-
Critical Infrastructure: Safety-critical power and control wiring in public buildings, power plant control rooms, industrial settings, and other installations where regulations require fire-resistant, low-smoke, zero-halogen cabling with enhanced temperature resistance.
