Product Overview
The CHEV90/NA is a robust, Fire Resistant marine communication cable designed for critical applications requiring both certified circuit integrity during a fire and superior mechanical protection. It combines a mica-reinforced EPR insulated core with a PVC inner sheath and a heavy-duty galvanized steel wire braid armor. This construction provides essential defense against impact, crushing, and tension, making it ideal for protecting vital safety circuits in exposed or high-risk areas onboard vessels, offshore platforms, and within industrial plants, all while ensuring operation per IEC 60331 under fire conditions.
Key Features & Benefits
-
Fire Survival with Mechanical Durability: Delivers certified Fire Resistance (IEC 60331) alongside the exceptional physical protection of a galvanized steel wire braid armor, safeguarding critical alarm and communication circuits from both fire and mechanical damage.
-
Optimized for Conduit & Protected Routing: The armored design with a single PVC inner sheath is engineered for installation within cable conduits, trunking, or protected trays where external abrasion is a concern, providing reliable performance without an additional outer sheath.
-
Rugged & Reliable Construction: The mica/EPR insulation ensures thermal stability and fire integrity, while the steel armor offers proven resistance to crushing, rodent attacks, and incidental impact.
-
Industry Standard Compliance: Manufactured in accordance with the IEC 60092 series for marine applications and key fire safety standards, ensuring global acceptance for mission-critical installations.
