Product Overview
The CJPJR85/SC is a premium halogen-free, flame-retardant marine flexible cable designed for applications demanding superior thermal and mechanical performance. It distinguishes itself with a fully cross-linked polyolefin (SHF2) sheath system, both inner and outer, offering enhanced temperature resistance and durability. Combined with flexible Class 5/6 conductors, XLPE insulation, and tinned copper wire braid armor, it is ideal for critical, high-reliability circuits in challenging environments on ships, offshore platforms, and in industrial settings.

Key Performance Characteristics
-
Enhanced Thermal Durability: Features a complete dual-sheath system made of cross-linked polyolefin (SHF2, codes PJ & 5). This material offers superior thermal endurance (typically rated up to 105°C) and better resistance to deformation under heat compared to standard thermoplastic sheaths.
-
Superior Flexibility with Complete Protection: Utilizes fine-stranded (Class 5/6) tinned copper conductors for excellent flexibility. The tinned copper wire braid provides effective electromagnetic shielding (EMC), while the tough, cross-linked outer sheath adds a layer of mechanical and environmental protection.
-
Comprehensive Fire Safety: Complies with IEC 60332-1 and IEC 60332-3-22 for flame retardancy. The halogen-free, low-smoke (LSF) construction minimizes corrosive gas emission and smoke density, enhancing safety in confined spaces.
-
Robust Mechanical & Environmental Resistance: The cross-linked outer sheath offers excellent resistance to abrasion, oils, chemicals, and weathering, providing durable protection for the internal copper braid armor and core.
-
Reliable Shielding: The tinned copper braid armor ensures good protection against electromagnetic interference (EMI) and offers corrosion resistance in marine atmospheres.
Standards & Compliance
This cable is designed and manufactured in compliance with key international marine and electrical standards:
-
IEC 60092-350, 353 (General construction and tests for shipboard power cables)
-
IEC 60228 (Conductors of insulated cables)
-
IEC 60092-360 (Insulating and sheathing materials)
-
IEC 60332-1 & IEC 60332-3-22 (Tests for flame retardancy)
Typical Applications
This high-performance flexible cable is suited for demanding installations requiring enhanced temperature resistance, shielding, and full mechanical protection:
-
Marine & Offshore: Critical power, control, and instrumentation circuits in high-ambient-temperature areas (e.g., engine rooms, near exhausts), for sensitive equipment requiring EMI shielding, and on offshore platforms where long-term durability is essential.
-
Industrial: Flexible connections in harsh industrial environments such as power generation, chemical plants, and automated machinery where exposure to heat, oils, and potential mechanical stress is expected.
