Product Overview
The CJPJP85/SC is a premium-grade, fully cross-linked marine power cable designed for the most demanding environments where exceptional thermal stability, mechanical durability, and flexibility are required. It distinguishes itself by utilizing Cross-linked Polyolefin (SHF2) for both its inner and outer sheaths, providing superior resistance to heat deformation, cracking, and mechanical stress compared to standard thermoplastic sheaths. Combined with XLPE insulation, a collective screen, and a flexible tinned copper wire braid armor, this cable offers an optimal balance of long-term reliability, safety, and ease of installation in dynamic or high-stress applications.
Key Features & Benefits
-
Full SHF2 Cross-linked Sheathing: Both inner and outer sheaths are made of Cross-linked Polyolefin (SHF2), offering maximum resistance to high temperatures, deformation, and mechanical damage. This ensures outstanding long-term integrity in harsh conditions.
-
Flexible & Corrosion-Resistant Armor: The braided armor of tinned copper wires provides excellent flexibility for easier pulling and routing, along with superior corrosion resistance in humid and salty marine atmospheres.
-
Comprehensive Fire Safety: All sheath and insulation materials are Halogen-Free and Low-Smoke (LSZH), significantly reducing toxic fumes and smoke density to enhance personnel safety and equipment protection during fire incidents.
-
Reliable Electrical Performance: XLPE (Cross-Linked Polyethylene) insulation guarantees stable electrical characteristics and thermal endurance for continuous operation at 90°C.
-
Effective EMI/RFI Shielding: The integrated collective copper screen protects against electromagnetic and radio-frequency interference, ensuring clean power transmission for sensitive onboard systems.
