Product Overview
The CHEPJ85/NC is a premium Fire Resistant marine-grade communication cable, engineered for critical circuits where maintaining signal integrity during a fire is essential. It combines Mica/EPR insulation for fire survival with comprehensive Low Smoke Halogen Free (LSHF) safety features. The inclusion of a Copper Braid Armor provides effective EMI shielding, making it ideal for sensitive communication and control systems on ships, offshore platforms, and in high-risk industrial plants that require both fire resistance and interference protection.
Key Features & Benefits
-
Certified Fire Resistance: Meets IEC 60331 standards to ensure continued circuit operation during a fire emergency.
-
Enhanced Safety & Environmental Protection: Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties minimize corrosive gases and toxic smoke, protecting personnel and equipment.
-
Dual Fire Performance: Combines Fire Resistant (IEC 60331) capability with additional Flame Retardant (IEC 60332-1 & -3-22) properties to prevent flame spread.
-
EMI Shielding & Flexible Armor: The Tinned Copper Wire Braid Armor offers excellent flexibility, good mechanical protection, and effective shielding against electromagnetic interference.
-
Robust Construction: Mica glass tape with EPR insulation ensures fire integrity, while double-layer Cross-linked Polyolefin (SHF2) sheathing provides superior environmental and chemical resistance.
