Product Overview
The CKEVP90/NA is a critical-circuit Fire Resistant, Screened, and Armored marine control cable engineered for power, lighting, and control systems where circuit integrity during a fire is paramount. Featuring a mica glass tape and EPR insulation core for certified fire resistance, an integrated EMI/RFI screen, and heavy-duty galvanized steel wire armor, this cable is protected by a single PVC inner sheath with no outer oversheath. This streamlined, grounding-ready design is built for vital safety and emergency systems in harsh marine, offshore, and industrial environments, complying with the stringent IEC 60331 fire resistance standard.
Key Features & Benefits
-
Certified Fire Resistance (IEC 60331): The mica glass tape barrier beneath EPR insulation ensures the cable maintains electrical circuit integrity and continues to operate for a critical period under direct flame, essential for emergency and safety-critical systems.
-
Robust Protection & Signal Integrity: The galvanized steel wire armor provides maximum mechanical protection against crushing and impact. An integrated electrical screen safeguards sensitive control signals from electromagnetic interference (EMI/RFI).
-
Grounding-Ready, Streamlined Construction: The single PVC sheath over the armor, with no outer oversheath, allows for direct access to the conductive steel armor for reliable grounding to a ship's hull or structural ground. This results in a more compact cable profile.
