Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The cable is engineered to maintain circuit integrity and continue operating for a specified period under direct flame exposure, which is critical for all emergency and life-safety circuits.
-
Durable PCP Sheath: The Polychloroprene (PCP, Neoprene) sheath provides strong resistance to oils, ozone, weathering, and abrasion, offering robust environmental protection.
-
High Flexibility & Lightweight: As an unarmored cable with flexible Class 5/6 conductors, it offers exceptional ease of handling, routing, and installation in conduits, cable trays, and control panels.
-
Flame Retardant: Complies with IEC 60332-1 and IEC 60332-3-22, helping to inhibit the spread of flame along the cable run.
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 requirements)
-
IEC 60228 (Conductors)
-
IEC 60092-360 (Insulation and sheath materials)
-
IEC 60331 (Fire Resistance)
-
IEC 60332-1 & IEC 60332-3-22 (Flame retardancy tests)
Typical Applications
This cable is specified for critical circuits within protected spaces where fire survival capability is required:
-
Marine & Offshore: Essential emergency circuits such as emergency lighting, alarm and detection systems, and control wiring within accommodation areas and control rooms on ships and offshore structures.
-
Industrial: Safety-critical power and control wiring in public buildings, hospitals, and industrial control panels where fire-resistant cabling is mandated for protected internal routes.
