Description

GENERAL SCOPE

– The fire resistant cables CVV/AWA (SWA)/FR for distribution systems are designed to maintain circuit integrity of those vital services and restrict the propagation of flames, they are proper used for public facilities…, rated voltage 0,6 /1 kV, fixed wiring.
– The fire resistant cables are properly used for public facilities, backup power systems, emergency systems, fire alarm systems, sprinklers, smoke detection and extraction equipment, emergency lighting and evacuation systems…

APPLIED STANDARD

TECHNICAL CHARACTERISTICS

– Rated voltage U0/U: 0,6/1 kV.
– Test voltage: 3,5 kV (5 minutes) .
– Maximum conductor temperature for normal operation is 70°C.
– Maximum conductor temperature for short-circuit (5s maximum duration) is:
– 140°C with Nominal area larger than 300mm2.
– 160°C with Nominal area up to and include 300mm2.
– Cables are subjected to fire at 950°C for 3 hours.
– The cables pass BS 6387 Cat. CWZ.
– The fire resistant cables have a significant reduced tendency to propagate fire.
– The cables must self-extinguish after removing the fire source.
