Product Overview
The CKEPJ80/NC is a high-performance Fire Resistant marine control cable designed for critical circuits where maintaining operation during a fire is essential. It features a robust construction with Mica/EPR fire-resistant insulation, a Halogen-Free, Low Smoke (LSHF) Cross-linked Polyolefin (SHF2) inner sheath, and Tinned Copper Braid Armor. This combination ensures circuit integrity, electromagnetic compatibility, and safety in demanding marine, offshore, and industrial environments, fully complying with IEC 60331 and IEC 60092 standards.
Key Features & Benefits
-
Certified Fire Resistance: Meets IEC 60331 requirements, guaranteeing the cable continues to function for a specified period under fire conditions, which is crucial for emergency control, alarm, and safety systems.
-
Effective EMI Shielding & Flexibility: The Tinned Copper Braid Armor provides excellent protection against electromagnetic interference (EMI) and offers good flexibility compared to steel armor, making it suitable for applications where both signal integrity and maneuverability are important.
-
Superior Fire Safety: Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) properties prevent the release of toxic/corrosive gases and reduce smoke density. Also compliant with Flame Retardant standards (IEC 60332).
-
Durable Construction: Mica glass tape with EPR insulation provides reliable fire survival and thermal stability up to 90°C. The SHF2 inner sheath offers robust chemical and environmental resistance.
