Product Overview
The CHEPJP85/NC is a premium Fire Resistant (FR) and Flame Retardant (FR) marine communication cable designed for critical circuits where continuous operation during a fire is essential. It features a robust construction with EPR insulation protected by mica glass tape, an EMI screening layer, tinned copper braid armor, and a complete double-sheathed, Low Smoke Halogen Free (LSHF) design. This cable ensures maximum signal integrity, mechanical protection, and fire safety for vital systems in marine, offshore, and high-risk industrial environments.
Key Features & Benefits
-
Highest Fire Safety Level: Integrates Fire Resistance (IEC 60331) to maintain circuit integrity under fire conditions with Flame Retardancy (IEC 60332) to prevent fire spread. Its Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) construction protects personnel and equipment.
-
Complete Environmental Protection: Features a unique double-layer SHF2 (cross-linked polyolefin) sheath system (Inner Sheath PJ + Outer Sheath 5), offering superior thermal, chemical, and mechanical protection. The outer sheath is available in standard black or other colors for identification.
-
Signal Integrity & Flexible Armor: The overall tinned copper braid or tape screen provides effective electromagnetic interference (EMI) shielding. The tinned copper wire braid armor (Code 8) offers flexible yet robust mechanical protection and serves as an additional shield.
-
Reliable Insulation System: The mica glass tape over EPR insulation core provides a proven, thermally stable barrier that is highly effective for fire-resistant performance.
