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
