Product Overview
The CHEPJ90/SC is a heavy-duty, conduit-optimized marine communication cable engineered for protected installations where maximum fire safety and mechanical protection are required. It combines EPR insulation, a Cross-linked Polyolefin (SHF2) inner sheath, and galvanized steel wire armor within a full Low Smoke Halogen Free (LSHF) Flame Retardant construction. Its “Without Outer Sheath” (0) design is specifically tailored for installation within conduits or ducts, offering a robust and safety-compliant solution for critical circuits in the most demanding marine and industrial environments.
Key Features & Benefits
-
Conduit-Optimized for Protected Pathways: The galvanized steel wire braid armor (9) provides supreme mechanical strength, while the absence of an outer sheath (0) minimizes cable diameter and friction, making it ideal for efficient installation within conduits, cable ducts, or enclosed trunking.
-
Superior Fire Safety Performance: Delivers full Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties, drastically reducing toxic fumes and smoke. Complies with stringent IEC 60332 flame retardancy standards.
-
Exceptional Durability: The Cross-linked Polyolefin (SHF2) inner sheath (PJ) offers excellent resistance to abrasion, chemicals, and environmental stress, ensuring the cable's integrity and LSHF properties are maintained.
-
Comprehensive Protection in a Streamlined Design: Provides the highest levels of mechanical (steel armor) and fire (LSHF/SHF2) protection in a form factor optimized for raceway installation.
