Product Overview
The CEVR90/NA is a heavy-duty, fire-resistant marine flexible power cable designed for critical safety circuits that demand both certified circuit integrity during a fire and superior mechanical strength. It combines durable Ethylene Propylene Rubber (EPR) insulation, a PVC inner sheath, and galvanized steel wire braid armor. This robust construction is engineered to ensure the continued operation of emergency and life-safety systems in the most physically demanding and high-risk environments on vessels, offshore installations, and in heavy industry.

Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The cable is designed to maintain electrical circuit integrity and continue functioning for a specified period under direct flame exposure, which is critical for emergency power, lighting, alarm, and fire pump control circuits.
-
Maximum Mechanical Protection: The galvanized steel wire braid armor provides exceptional resistance to crushing, impact, abrasion, and rodent damage, protecting the critical fire-resistant core in exposed or hazardous routing paths.
-
Superior EPR Insulation: Ethylene Propylene Rubber (EPR) offers excellent dielectric properties, thermal stability, and long-term resistance to heat and moisture, ensuring reliable power transmission.
-
High Flexibility: Despite its heavy-duty armor, the use of flexible Class 5/6 conductors ensures the cable remains manageable for installation in complex cable trays and confined spaces.
-
Flame Retardant: Complies with IEC 60332-1 and IEC 60332-3-22, helping to inhibit the spread of flame along the cable run.
-
Corrosion-Resistant Armor: The galvanized coating on the steel wire provides protection against corrosion in humid and saline marine atmospheres.
Standards & Compliance
This cable is designed and tested in accordance with key international marine and fire safety standards:
-
IEC 60092-350, 353 (General construction and armor requirements)
-
IEC 60228 (Conductors)
-
IEC 60092-360 (Insulation and sheath materials)
-

-
IEC 60332-1 & IEC 60332-3-22 (Flame retardancy tests)
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 power feeds to emergency generators, fire pump power and control circuits, and critical alarm systems on ships and offshore platforms, especially in areas prone to physical damage.
-
Heavy Industry & Critical Infrastructure: Safety-critical power and control wiring in power generation plants, chemical facilities, mining, and heavy machinery where both fire resistance and high mechanical protection are required by safety protocols.
