Product Overview
The CJPJP/SC is a specialized, high-performance unarmored marine power cable designed for fixed installations where superior thermal/mechanical performance from the sheath material and excellent EMI protection are required, without the need for metallic armor. Its defining feature is the Cross-linked Polyolefin (SHF2) inner sheath, which provides enhanced resistance to heat deformation and mechanical stress compared to standard thermoplastic sheaths. Combined with XLPE insulation and a collective copper screen, this lightweight and flexible cable is the ideal choice for protected routes where fire safety, signal integrity, and long-term sheath durability are priorities.
Key Features & Benefits
-
Advanced Inner Sheath Material: Utilizes a Cross-linked Polyolefin (SHF2) inner sheath, offering superior resistance to high temperatures, cracking, and deformation for improved long-term reliability in challenging environments.
-
Maximum Flexibility & Lightweight: The unarmored (no metallic armor) construction ensures excellent flexibility and ease of handling, reducing installation time and weight, ideal for cable trays, conduits, and tight spaces.
-
Essential Fire Safety: All materials are Halogen-Free and Low-Smoke (LSZH), minimizing the release of toxic/corrosive gases and smoke density to enhance safety during fire incidents.
-
Stable Electrical Performance: XLPE (Cross-Linked Polyethylene) insulation provides reliable electrical characteristics and thermal endurance for continuous operation at 90°C.
-
Effective EMI Shielding: The integrated collective copper screen protects power and control signals from electromagnetic interference (EMI), ensuring system integrity in sensitive applications.
