FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering and can be used in various industries. Cable includes core containing at least one conductor or pair, triple twisted current conductors (1), each of which is applied insulation (2) of organosilicon rubber with reinforcing filler, as well as outer shell, which is core. Isolated conductor or two, three twisted current conductors applied braiding from metal or nonmetallic materials with melting point or decomposition of more than 850°C. Braiding provides reinforcement protective ceramic layer formed during burning of combustible materials of structural elements of cable. Braiding is applied on core and outer shell.
EFFECT: technical result consists in providing vibration resistance of cable in conditions of naked flame and maintaining its serviceability after elimination of fire with simultaneous action of mechanical loads.
