Product Overview
The CHEPJ80/NC is a specialized Fire Resistant marine communication cable designed for critical circuits requiring both fire integrity and electromagnetic shielding. It features a Mica/EPR insulation system certified to IEC 60331, coupled with Low Smoke Halogen Free (LSHF) properties for enhanced safety. The key distinguishing feature of this version is its Uni-Sheath Construction with an exposed Tinned Copper Wire Braid Armor, making it a lighter and more flexible solution for applications where an outer sheath is not mandated but fire resistance and EMI protection are essential.
Key Features & Benefits
-
Certified Fire Resistance: Complies with IEC 60331, ensuring circuit integrity and continued operation during a fire emergency.
-
Comprehensive Safety: Combines Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties with Flame Retardancy (IEC 60332) for maximum personnel and asset protection.
-
Effective EMI Shielding: The outer Tinned Copper Wire Braid Armor provides excellent protection against electromagnetic interference, crucial for sensitive communication and control signals.
-
Optimized & Flexible Design: The Uni-Sheath Construction (without a separate outer sheath over the armor) results in a lighter, more flexible, and easier-to-install cable, ideal for confined spaces.
-
Durable Core Construction: Utilizes Mica glass tape with EPR insulation and a Cross-linked Polyolefin (SHF2) inner sheath to maintain performance in harsh marine and industrial environments.
