Product Overview
The CEFR90/NA is a heavy-duty, fire-resistant marine flexible power cable engineered for critical safety circuits that demand both certified circuit integrity during a fire and superior mechanical protection. It combines Ethylene Propylene Rubber (EPR) insulation for electrical reliability, a resilient Polychloroprene (PCP) inner sheath, and galvanized steel wire braid armor. This robust construction is designed to ensure the continued operation of emergency and life-safety systems in the most physically demanding and hazardous environments on vessels and offshore installations.

Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The cable is designed to maintain circuit integrity and continue functioning for a specified period under direct flame, which is critical for emergency power, lighting, alarm, and control circuits.
-
Maximum Mechanical Protection: The galvanized steel wire braid armor provides exceptional resistance to crushing, impact, abrasion, and rodent damage, safeguarding the critical fire-resistant core in exposed or high-risk locations.
-
Durable Environmental Resistance: The Polychloroprene (PCP, Neoprene) inner sheath offers strong protection against oils, ozone, weathering, and chemicals, ensuring performance in harsh conditions.
-
High Flexibility: Despite its heavy-duty armor, the use of flexible Class 5/6 conductors ensures sufficient flexibility for installation in essential cable routes and trays.
-
Flame Retardant: Complies with IEC 60332-1 and IEC 60332-3-22, helping to inhibit the spread of flame along the cable run.

Typical Applications
This armored fire-resistant cable is specified for the most critical circuits where operation during a fire and physical survivability are non-negotiable:
-
Marine & Offshore: Essential feeds to emergency generators, fire pump power and control circuits, and critical alarm systems on ships, oil platforms, and offshore structures, especially in areas prone to physical damage.
-
Heavy Industry & Critical Infrastructure: Safety-critical power and control wiring in power generation plants, chemical facilities, and heavy machinery where both fire resistance and high mechanical protection are required.
