Fire Resistant UTP CAT5 Data Cables



The cables are desgined for structure wiring, compatible with all known connection systems according to EN 50173. Based on the design for structured wiring (found in IEC 61156 and BS EN 50288), this cable brings together high frequency data transmission and circuit integrity in four pair cable that will continue to transmit data even when being directly attacked by fire.

Conductors: Plain annealed copper wire, solid according to IEC(EN) 60228 class 1.

Insulation: PE wrapped with fire resistant silicone rubber compound type EI2 as per BS 7655-1.1.

Twisted Pairs: Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk.

Cabling Elements: Insulated cores are twisted to form pairs with varying lay length to minimize crosstalk. Two-pair cable had four cores laid in quad formation.

Cabling: Pairs are cabled together in concentric layers.

Outer Sheath: Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1 (Thermosetting LSZH compound type SW2-SW4 as per BS 7655-2.6 can be offered.)
