Application

Halogen-free conductors used for installations in dry environment for wiring of lighting fixtures, tools and other devices in facilities where human lives or valuable property need to be protected against damages caused by fire. Laid on or under plaster, same as in closed installation canals. For inner wiring of switchboards and control panels up to the nominal voltage of 750/1000 V.

advantages:
– halogen-free, no release of toxic or corrosive gases under fire
– reduced smoke occurrence under fire
