Product Overview
The CHEF82/NA is a Fire Resistant (FR) marine communication cable designed for essential circuits that must maintain functionality during a fire emergency. It features a Mica Glass Tape and EPR insulation system and is protected by a robust PCP inner sheath, Copper Wire Braid armor, and a final PVC Outer Sheath. This construction provides certified fire survival capability (IEC 60331), EMI shielding, and environmental protection for critical safety and communication systems on vessels and in industrial plants.
Key Features & Benefits
-
Certified Fire Resistance: Manufactured to meet IEC 60331 standards, ensuring circuit integrity continues to operate for a specified period under direct flame exposure, which is critical for alarms and emergency communications.
-
Comprehensive Safety Design: Combines fire resistance with Low Smoke, Halogen-Free (LSHF) properties (IEC 60754, 61034) and high Flame Retardancy (IEC 60332) to minimize fire hazard risks.
-
Durable & Protective Construction: The Mica/EPR insulation ensures thermal stability and fire protection, while the Copper Wire Braid (Armor 8) provides effective electromagnetic shielding and mechanical strength. The PVC Outer Sheath offers additional abrasion, chemical, and weather resistance.
-
Versatile Installation: Available with a Black or other colored PVC outer sheath, facilitating easy circuit identification and compliance with installation color-coding schemes.
