Product Overview
The CHEVP/NA is a premium Fire Resistant (FR) marine communication cable engineered for critical circuits that must maintain functionality during a fire emergency. It features a robust construction with Mica Glass Tape & EPR insulation, a PVC sheath, and an overall electrical screen. Certified to the stringent IEC 60331 standard for fire resistance, it ensures circuit integrity under flame, while also meeting Halogen Free (IEC 60754), Low Smoke (IEC 61034), and Flame Retardant (IEC 60332) requirements. This cable is designed for essential telecommunication and safety systems on ships, offshore platforms, and in high-risk industrial plants.
Key Features & Benefits
-
Critical Fire Integrity: Certified to IEC 60331 for Fire Resistance, ensuring the cable can continue to operate for a specified period under direct flame, which is crucial for alarm, communication, and emergency systems.
-
Enhanced Safety Features: Combines fire resistance with Halogen-Free and Low Smoke properties (IEC 60754 & 61034) to minimize toxic and corrosive gas emissions, aiding safe evacuation.
