Product Overview
The CJPJR90/NC is a premium halogen-free, low-smoke, fire-resistant marine flexible power cable designed for the most critical circuits in demanding environments. It combines a certified fire-resistant mica/XLPE insulation core with a high-temperature cross-linked polyolefin (SHF2) inner sheath and galvanized steel wire braid armor. This construction ensures circuit integrity during a fire, offers superior mechanical protection, and performs reliably in higher ambient temperatures, making it essential for vital emergency and safety systems.

Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The mica glass tape and XLPE insulation system is engineered to maintain circuit integrity and continue functioning for a specified period under direct flame, a critical requirement for life-saving emergency circuits.
-
High-Temperature Resistant Inner Sheath: The cross-linked polyolefin (SHF2) inner sheath provides enhanced thermal stability and resistance to deformation in elevated ambient temperature environments compared to standard thermoplastic sheaths.
-
Superior Mechanical Protection: The galvanized steel wire braid armor offers maximum resistance to crushing, impact, and tensile stresses, safeguarding the critical fire-resistant core in exposed or physically demanding locations.
-
Complete Fire Safety Suite: Integrates the highest safety standards: Fire Resistance (IEC 60331), Flame Retardancy (IEC 60332), zero halogen emission (IEC 60754), and low smoke density (IEC 61034) to protect personnel and equipment.

Typical Applications
This armored fire-resistant cable is specified for critical safety circuits that must survive both fire and harsh physical conditions, particularly in warmer environments:
-
Marine & Offshore: Essential power feeds to emergency generators, fire pump control circuits, and critical alarm systems located in engine rooms, machinery spaces, or other high-temperature and high-risk areas on ships and offshore platforms.
-
Critical & Heavy Industry: Safety-critical wiring in power plants, industrial facilities, and infrastructure where regulations demand both certified fire-resistant cabling and robust mechanical protection against impact and crush.
