Product Overview
The CHEPJP90/NC is an advanced Fire Resistant (FR) and Flame Retardant (FR) marine communication cable, designed to maintain circuit integrity and ensure continuous operation of critical systems during a fire. Featuring EPR insulation with mica glass tape, a galvanized steel wire armor, and an overall Low Smoke Halogen Free (LSHF) construction, it provides the highest level of safety and reliability for essential communications on vessels and offshore installations, as well as in hazardous industrial areas.
Key Features & Benefits
-
Superior Fire Performance: Combines Fire Resistance (IEC 60331) to ensure functionality during fire, with Flame Retardancy (IEC 60332) to inhibit fire spread. Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties enhance personnel safety during evacuation.
-
Robust Mechanical & EMI Protection: Galvanized steel wire braid armor provides high tensile strength and mechanical protection. An overall tinned copper braid or tape screen offers effective electromagnetic interference (EMI) shielding for signal integrity.
-
High-Temperature & Durable Construction: Mica/EPR composite insulation ensures excellent thermal stability and fire-resistant properties. The cross-linked polyolefin (SHF2) inner sheath offers enhanced thermal and chemical resistance.
-
Marine & Heavy Industrial Grade: Built to withstand extreme environmental challenges, including fire, mechanical stress, and corrosive conditions.
