Product Overview
The CHEV92/NA is a heavy-duty, Fire Resistant (FR) marine communication cable designed for the highest level of circuit integrity and mechanical protection in demanding environments. It features a robust mica/EPR insulated core certified for fire survival (IEC 60331), protected by an internal PVC inner sheath, a galvanized steel wire braid armor, and a final PVC outer sheath. This double-sheathed, armored construction is engineered to withstand severe physical impact, abrasion, and fire, making it ideal for exposed or high-risk routing of critical safety circuits on vessels, offshore platforms, and in industrial plants.
Key Features & Benefits
-
Maximum Circuit Integrity & Protection: Combines certified Fire Resistance (IEC 60331) with a heavy-duty galvanized steel wire braid armor, offering superior mechanical protection against crushing, impact, and rodent damage, ensuring vital systems remain operational.
-
Durable Double-Sheath Design: The PVC inner sheath provides a bedding layer for the armor, while the robust PVC outer sheath offers enhanced overall environmental, chemical, and abrasion resistance for long-term reliability.
-
Ruggedized Marine Construction: The armored, double-sheathed design is specifically built to survive harsh maritime and industrial conditions, including demanding cable tray, direct-burial (where specified), or exposed deck installations.
-
Certified Safety: Complies with stringent fire performance (IEC 60331) and marine design (IEC 60092) standards, ensuring global acceptance for safety-critical applications.
