Product Overview
The CHEV/NA is an essential, cost-effective Fire Resistant marine communication cable designed to ensure the integrity of critical circuits during a fire. Featuring core mica-reinforced EPR insulation for fire survival and a durable PVC outer sheath, it provides reliable, certified fire resistance (IEC 60331) for vital systems in maritime and industrial applications where complex armor or screening is not required. This cable offers a robust safety solution compliant with the IEC 60092 marine standard series.
Key Features & Benefits
-
Certified Fire Resistance: Meets IEC 60331 standard, ensuring continued operation of emergency alarm and communication circuits during a fire, crucial for personnel safety and emergency response.
-
Reliable Core Construction: Utilizes mica glass tape with EPR insulation, a proven combination that provides thermal stability (90°C) and maintains circuit integrity under fire conditions.
-
Durable & Practical: The overall PVC sheath offers good mechanical protection, abrasion resistance, and flexibility for easier installation in various onboard or industrial conduits and trays.
-
Cost-Effective Safety: Provides essential fire-resistant performance in a simplified, non-armored construction, making it an economical choice for mandatory safety circuits.
