COMBO CABLE, armored, low-hazard toxicity GAS NETWORKS FOR electrified transport DC

摘要

The claimed utility model relates to the field of cable technology, namely, to the structures of the combined cable for power transmission and distribution in stationary installations for DC, for example in networks electrified passenger transport. The technical result achieved when implementing the claimed utility model is to design the structure of the electric cable, the equivalent toxicity index which combustion plastics products is not less than 121 g / m ^3, providing the ability to control its operating mode, is provided by the fact that the cable combination comprising one basic multiwire electrical conductor made of copper or aluminum, which are sequentially laid extrusion phase and zolyatsiya and outer sheath, according to the utility model in the outer layer core multiwire conductor are additional isolated control solid or stranded conductive strands amount one or more, in this case, phase insulation of the main multi-wire conductor, insulation control solid or stranded conductive cores and the outer shell made of polyvinylchloride composition with an oxygen index of not less than 28% and an equivalent index m Toxic combustion products of polymeric materials is not less than 121 g / m ^{3 January} bp f-ly, 12 ZP f ly-1-yl.
