Fire Resistant Cable

Prysmian FP100

Prysmian FP100 is fire resistant single core cable for use in steel conduit or trunking when using BS5266-1:2005.

FP100 is specified for use when upgrading existing steel conduit systems to current specification and also for new build projects featuring metallic trunking – the fire resistant cable can be used for emergency lighting, fire detection and fire alarm circuits for systems that do not require twisted pairs or a built-in metallic screen.

Prysmian FP100 fire resistant cable is suitable for use as part of a ‘standard’ or ‘enhanced’ fire resistant cable system and can help solve the installation issues when surface or void installation is not an option.
