ELECTRIC MULTICORE CABLE Russian patent published in 2018 - IPC H01B11/02 

FIELD: electricity.

SUBSTANCE: electric multicore cable refers to electrical engineering and designed for industrial data networks, control stations, signalling, etc. In electrical multicore cable, containing a core of twisted copper or copper tinplated conductors covered with insulation, or of twisted concentric layers, in turn, twisted in pairs, threes or fours of copper or copper tinplated conductors covered with insulation, on top of which wrapping, collective screen and protective covering are consistently imposed, and inner covering is superimposed between the collective screen and protective covering, the collective screen is executed in the form of a winding of alumopolymer tape with contact multiwire tinplated copper conductor or as braiding of copper wires, or tinplated copper wires with coefficient of surface density not less than 75%, or in the form of a winding of alumopolymer tape, or combined material based on aluminium foil.

EFFECT: increase the cable resistance to aggressive environments, as well as its noise immunity.
