Product Overview
The CJ95/NC represents a premium, compact fire resistant marine cable engineered for the most extreme conditions where circuit integrity during a fire, maximum mechanical strength, and exceptional sheath durability are all critical. Featuring a streamlined construction without a separate inner sheath, it integrates a fire-survival Mica/XLPE insulated core (IEC 60331), a high-strength galvanized steel wire braid armor, and a robust Cross-linked Polyolefin (SHF2) outer sheath. This design delivers the ultimate combination of certified fire safety, superior long-term environmental resistance, and supreme physical protection in a space-efficient package for the most demanding safety-critical circuits.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): Guarantees that vital emergency and safety circuits (e.g., emergency generator feeds, fire pump systems, critical alarms) maintain operation for a specified duration under direct flame and impact, which is non-negotiable for life safety.
-
Maximum Mechanical & Thermal Sheath Protection: A high-strength galvanized steel wire braid armor provides ultimate crush and impact resistance. Combined with a Cross-linked Polyolefin (SHF2) outer sheath, it offers unparalleled resistance to high temperatures, deformation, cracking, chemicals, and abrasion.
-
Compact & High-Efficiency Design: The absence of a separate inner sheath creates a more streamlined and material-efficient cable structure, optimizing space and weight for installations where these factors are constrained, without compromising on performance.
-
Fire-Survival Core Technology: The Mica Glass Tape layer over XLPE insulation forms a robust, heat-resistant ceramic barrier, maintaining electrical insulation integrity at extreme temperatures to prevent circuit failure during a fire.
-
Enhanced Fire Safety (LSZH): Rated NC (Halogen Free, Low Smoke, Fire Resistant), it drastically reduces the emission of corrosive/toxic gases and smoke density, enhancing personnel safety and minimizing secondary damage during a fire incident.
