Wires for rolling stock with heat-resistant insulation, flame retardant while laying in the beam, fire-resistant, low-outgassing SMOKE

摘要

The invention relates to the cable industry and the electrical industry can be used for the rail and public transport when joining the inner and outer electric rolling stock, including underground. The massive use of cable products in the heavy rail equipment in areas with large concentrations of people today put forward by one of the first places the task to improve the level of fire safety. Particularly relevant issue of increasing fire for the subway. Designed wire intended for internal and external connections electric rolling stock rail and public electric transport, including underground, with rated voltage up to 4000 V. The main factors are cost efficiency: - increasing the maximum temperature on the conductive core, which allows to increase the current load on the wire; - increase the fire resistance, low smoke, gas evolution on burning; - increase the reliability and fire wire.
