Fire Resistant Data CableFire Resistant Data Cable BS5839


CSE cables offer a range of high performance fire resistant data cables designed to continue transmitting data even when being directly attacked by fire. This allows safe monitoring of evacuation routes without putting additional lives at risk.

We are able to offer the twisted pair cables in 1, 2 and 4 pair construction. Each with a 0.63mm size conductor, overall screen plus a drain wire and Tinned Copper Wire Braid with a LSZH outer sheath.
