Product Overview
The CHEVP90/NA is a high-performance, Fire Resistant marine communication cable designed for mission-critical circuits where circuit integrity must be maintained during a fire. It combines EPR insulation with mica glass tape, individual pair screening, and galvanized steel wire armor to provide unparalleled protection against fire, mechanical stress, and electromagnetic interference (EMI). This cable is engineered to meet the stringent safety and performance requirements of the IEC 60092 series and IEC 60331 for fire resistance.
Key Features & Benefits
-
Superior Fire Survival: Constructed with mica glass tape and EPR insulation, the cable is certified to IEC 60331 standards, ensuring continued operation of essential systems in the event of a fire.
-
Enhanced Safety & Protection: Features Low Smoke, Halogen-Free (LSHF) properties (IEC 60754, IEC 61034) and high Flame Retardancy (IEC 60332). The tinned copper braid/Al-PET tape screen provides effective EMI shielding, while the galvanized steel wire armor offers robust mechanical protection.
