Prysmian FP600 Cable

Prysmian FP600 ® is a unique enhanced performance fire resistant power cable, designed specifically to meet the more onerous fire survival requirements now requested by regulators and specifiers for many fire fighting and life safety applications. Its superior mechanical protection provided by an interlocking steel tape armour is, unlike standard single wire armour designs, maintained to a high level under fire conditions. This armour design ensures that FP600 meets the new generation fire test requirement currently given in BS7346-6:2005 “Components for smoke and heat control systems – Part 6 Specification for cable systems” which involves direct mechanical impact and water jet application under fire conditions.

FP600 achieves the maximum 120 minute rating under the BS7346-6 test conditions, which is required for fire fighting BSEN60332-1-2.
