Product Overview
The CHEPJP90/SC is a heavy-duty Low Smoke Halogen Free (LSHF), screened, and armored marine communication cable designed for protected installations within conduits, ducts, or trunking systems. It combines the fire safety of LSHF materials (IEC 60754, 61034) with the mechanical strength of galvanized steel wire armor and the signal integrity of a metallic screen. Featuring EPR insulation and a cross-linked polyolefin (SHF2) inner sheath, this cable is engineered for critical circuits in marine and industrial environments where internal protection is provided by the installation method.
Key Features & Benefits
-
Conduit-Optimized LSHF Design: The "Without Outer Sheath" (0) construction is specifically for installation within protective conduit, cable duct, or trunking, reducing diameter and friction. Maintains full Halogen-Free, Low Smoke Flame Retardant (SC) safety properties.
-
Robust Mechanical & EMI Protection: Galvanized Steel Wire Braid armor (9) offers superior resistance to crushing and impact. A tinned copper braid or foil screen (P) provides effective shielding against electromagnetic interference (EMI).
-
Enhanced Fire Safety: Complies with IEC 60754 (Halogen Free), IEC 61034 (Low Smoke), and IEC 60332 (Flame Retardant) standards, minimizing toxic fumes and fire propagation in bundled applications.
-
Durable Construction: EPR insulation ensures thermal stability up to 90°C, while the SHF2 inner sheath provides a durable, chemically resistant layer beneath the armor.
