Electrical contractors select the 6491B 2.5mm grey cable specifically for identifying secondary power circuits within conduit or trunking systems. Furthermore, the grey insulation helps installers distinguish between different phases or functional runs in complex panels. Because the cable utilizes Low Smoke Zero Halogen (LSZH) technology, it significantly reduces risks in the event of a fire. Consequently, the sheath emits minimal smoke and zero corrosive gases. Therefore, this cable is the ideal choice for high-specification projects like hospitals and data centres.

In addition to its fire-safe properties, the 2.5mm² stranded copper conductor offers excellent current-carrying capacity for power circuits. As a result, you can pull this cable through containment systems with ease while maintaining maximum electrical efficiency. Moreover, the thermosetting LSZH insulation supports operating temperatures up to 90°C. Because this cable is BASEC approved and meets BS EN 50525-3-41 standards, it fully complies with the latest UK wiring regulations. Finally, we supply this cable on a sturdy 100m drum to ensure efficient handling and reduced waste on-site.
