Rated voltage U0/U: 0,6/1 kV.
Test voltage: 3,5 kV (5 minutes).
Maximum conductor temperature for normal operation is 70C.
Maximum conductor temperature for short-circuit (5s maximum duration) is:
140C with Nominal area larger than 300mm2.
160C with Nominal area up to and include 300mm2.
Wires are subjected to fire at 9500C for 3 hours.
Wires pass BS 6387 Cat. CWZ.
The fire resistant wires have a significant reduced tendency to propagate fire.
The wires must self-extinguish after removing the fire source.
