6491B 4.0mm² LSZH Single Core Conduit Cable – BROWN (100m Drum)

High-Power Live Phase Wiring
Electricians choose the 6491B 4.0mm brown cable for high-power circuits. This single-core wire identifies live phase runs inside conduit or trunking. Furthermore, the 4.0mm² copper core handles a higher load than standard lighting wires.
Because this cable uses LSZH technology, it improves building safety. Specifically, the sheath emits very little smoke if a fire starts. Consequently, this protects people in busy places like schools and hospitals. Therefore, it is the best choice for safe, modern power systems.
Efficient Installation on Site
In addition to safety, the stranded copper core offers great flexibility. As a result, you can pull this wire through tight pipes with very little effort. Moreover, the tough insulation works well in heat up to 90°CBecause this cable meets BS EN 50525-3-41 standards, it satisfies all UK rules.
Professional Trade Drums
Finally, we supply this cable on a strong 100m drum. This reel makes handling on-site fast and keeps your van tidy. Specifically, it helps you measure runs accurately and reduces wire waste on large jobs.
