Electrical professionals select the 6491B 2.5mm black cable specifically for wiring power circuits within conduit, trunking, or internal building pipework. Furthermore, the 2.5mm² conductor size offers a higher current-carrying capacity than standard lighting singles. Because the insulation uses advanced Low Smoke Zero Halogen (LSZH) technology, it significantly enhances safety in public and commercial spaces. Consequently, during a fire, the cable emits very little smoke and zero corrosive gases. Therefore, this cable is the ideal choice for hospitals, data centres, and high-rise developments.

In addition to its fire-safe properties, the stranded copper conductor ensures maximum durability and flexibility during installation. As a result, you can pull this wire through complex containment systems with minimal resistance. Moreover, the thermosetting LSZH insulation supports an operating temperature up to 90°C. Because this cable is BASEC approved and meets BS EN 50525-3-41 standards, it satisfies all current UK electrical regulations. Finally, we supply this cable on a robust 100m drum, which ensures you have plenty of length for large-scale industrial or commercial runs.
