Product Overview
The CJPJR/SC is a high-performance, halogen-free, and flame-retardant marine flexible power cable designed for applications where superior temperature resistance and flexibility are required, but mechanical armor is not. Its defining feature is the use of a cross-linked polyolefin (SHF2) sheath, offering enhanced thermal stability. Combined with fine-stranded Class 5/6 conductors and XLPE insulation, it provides a reliable, lightweight, and safe wiring solution for internal and protected circuits in high-ambient-temperature areas on ships and in industrial settings.

Key Performance Characteristics
-
Enhanced High-Temperature Resistance: The single sheath is made from cross-linked polyolefin (SHF2, code PJ), a material engineered for improved thermal endurance and deformation resistance in elevated temperature environments compared to standard thermoplastic (SHF1) sheaths.
-
Superior Flexibility & Light Weight: Utilizing fine-stranded (Class 5/6) tinned copper conductors and an unarmored design, this cable offers exceptional flexibility and is lightweight, facilitating easy installation, routing in tight spaces, and reducing overall weight.
-
Flame Retardant & Safety Compliant: Meets IEC 60332-1 and IEC 60332-3-22 for flame retardancy. The halogen-free, low-smoke construction minimizes corrosive gas emission and reduces smoke density, enhancing safety during fire incidents.
-
Environmental Durability: The SHF2 sheath provides good resistance to oils, moisture, and chemicals, ensuring reliable performance in protected but potentially demanding environments.
Standards & Compliance
This flexible cable is manufactured in accordance with key international marine and electrical standards:
-
IEC 60092-350, 353 (General construction and requirements 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 unarmored, high-temperature flexible cable is ideally suited for installations within protected enclosures where ambient temperatures are elevated:
-
Marine & Offshore: Internal wiring for control panels, switchgear, instrumentation, and auxiliary circuits located in engine control rooms, galleys, or other areas with higher ambient temperatures on ships and offshore platforms.
-
Industrial: Power and control wiring in control systems, panels, and machinery within industrial plants, power stations, and manufacturing facilities where higher temperature resistance is needed without the requirement for mechanical armor protection.
