FIRE RESISTANT POWER CABLE WITH RUBBER INSULATION AND SHELLS FROM FLAME RESISTANT, HALOGEN-FREE COMPOSITIONS

摘要

The utility model relates to cable technology, namely to the structures of power cables with rubber insulation, intended for the transmission and distribution of electrical energy in electrical networks at a rated alternating voltage of 1 and 3 kV, 50 Hz.;The fire-resistant power cable contains at least one conductive core, a winding made of mica-containing tapes, insulation made of ethylene-propylene rubber, an inner and outer sheath made of fire-resistant ceramic-forming halogen-free compositions with an oxygen index of at least 35.
