Product Overview
The CHEPFP90/SC is a heavy-duty, Low Smoke Halogen Free (LSHF) marine communication cable designed for installation within protective conduits, ducts, or trunking systems. It features a galvanized steel wire armor for superior mechanical protection and a dedicated metallic screen for EMI shielding, all within a Halogen-Free, Low Smoke Flame Retardant (SC) construction. With its “Without Outer Sheath” (0) design and Thermoplastic Polyolefin (SHF1) inner sheath, this cable is engineered to provide maximum safety and durability for critical circuits in demanding environments where external protection is provided by the installation method.
Key Features & Benefits
-
Conduit-Optimized, Armored Design: The galvanized steel wire braid armor (9) offers unmatched crushing resistance, while the absence of an outer sheath (0) reduces cable diameter and friction, making it ideal for pulling into conduits, cable ducts, or enclosed trunking.
-
Superior Fire Safety Performance: Provides full Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties, crucial for minimizing hazardous fumes and maintaining visibility during a fire. Complies with IEC 60332 flame retardancy standards.
-
Effective EMI/RFI Shielding: The integrated tinned copper braid or foil screen (P) protects sensitive telecommunication and instrumentation signals from electromagnetic interference, ensuring reliable data transmission in electrically noisy environments.
-
Robust & Cost-Effective: The EPR insulation ensures thermal stability (90°C), and the SHF1 inner sheath provides a tough, chemically resistant layer, offering a durable solution that balances performance with cost-effectiveness.
