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, a critical requirement for all life-safety and emergency circuits.
-
Halogen-Free & Low Smoke Safety: Complies with IEC 60754 (halogen-free) and IEC 61034 (low smoke density). This significantly reduces the emission of corrosive gases and dense smoke during a fire, enhancing personnel safety and visibility in confined spaces.
-
High-Temperature Resistant Sheath: The cross-linked polyolefin (SHF2) sheath offers improved thermal endurance and deformation resistance in elevated ambient temperature environments, ensuring long-term sheath integrity where standard thermoplastic sheaths may degrade.
-
Superior EPR Insulation: Ethylene Propylene Rubber (EPR) provides excellent dielectric properties, outstanding long-term thermal stability, and high flexibility for reliable electrical performance.
-
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.

Typical Applications
This cable is specified for critical circuits within protected spaces where fire survival, enhanced safety from fumes, and performance in warmer environments are mandatory:
-
Marine & Offshore: Essential emergency circuits such as emergency lighting, alarm and detection systems, and control wiring within engine control rooms, machinery spaces, or other areas with higher ambient temperatures on ships and offshore structures.
-
Critical Infrastructure: Safety-critical power and control wiring in public buildings, power plant control rooms, and industrial settings where regulations require fire-resistant, low-smoke, zero-halogen cabling with enhanced temperature resistance.
