Product Overview
The CHEVP92/NA is a premium-grade, steel wire armoured (SWA) marine communication cable engineered for the most critical circuits where fire resistance and mechanical durability are non-negotiable. It is designed to maintain circuit integrity during a fire emergency, certified to the stringent IEC 60331 standard. The cable features a Mica Glass Tape & EPR composite insulation system, an overall electrical screen, galvanized steel wire braid armor, and a PVC outer sheath. This robust construction ensures reliable operation of vital safety and communication systems on ships, offshore platforms, and in high-risk industrial facilities.
Key Features & Benefits
-
Guaranteed Fire Integrity: Certified to IEC 60331 for Fire Resistance, ensuring continuous operation of essential circuits (e.g., alarms, emergency communications) under direct flame for a specified duration.
-
Maximum Mechanical Protection: The galvanized steel wire braid armor provides superior resistance to crushing, impact, and rodent damage, making it suitable for exposed, buried, or high-risk installation routes.
-
Enhanced Safety & Signal Clarity: Combines fire resistance with Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties. The overall screen (tinned copper braid or Al/PET tape) ensures protection against electromagnetic interference (EMI) for clear signal transmission.
-
Complete Environmental Protection: The full construction—including inner sheath, armor, and PVC outer sheath—offers comprehensive protection against moisture, oils, and mechanical stress.
