Product Overview
The CHEF80/NA is a specialized Fire Resistant (FR) marine communication cable designed for essential circuits that must maintain operation during a fire. Its core construction features Mica Glass Tape and EPR insulation with a PCP inner sheath, protected by a Copper Wire Braid armor. Notably supplied without an outer sheath, this configuration is ideal for installations within protective conduits, ducts, or panels where the robust armor provides the final mechanical layer, ensuring compliance with IEC 60331 for circuit integrity under fire conditions.
Key Features & Benefits
-
Certified Fire Resistance: Engineered to meet IEC 60331 standards, guaranteeing continued functionality of critical safety and communication systems during a fire emergency.
-
Integrated Safety Features: Combines fire resistance with Low Smoke, Halogen-Free (LSHF) properties (IEC 60754, 61034) and high Flame Retardancy (IEC 60332) for comprehensive hazard mitigation.
-
Optimized for Protected Installations: The Copper Wire Braid armor (Code 8) serves as the final layer, providing excellent electromagnetic shielding and mechanical protection. The absence of an outer sheath (Code 0) makes it suitable for streamlined installation inside sealed conduits, cable trays, or machinery panels.
-
Robust Core Construction: Mica/EPR insulation ensures superior thermal and fire protection, while the PCP inner sheath offers additional resistance to oil, chemicals, and heat.
