Application

Halogen-free, flame resistant installation cables are mostly used for telecommunication. The electrostatic screening considerably reduces effect of outer electrical interferences. In case of fire no flame propagation and low smoke density. These flame-resistant cables are used for fixed installation in all locations where a special protection against fire and fire damage to human life and equipment is necessary such as in industry complexes, power stations, public buildings, hotels, airports, subways, theatres, hospitals etc.
