FIELD: electrical engineering. SUBSTANCE: electric cable has three current-conducting cores positioned in parallel in one plane. Every core is provided with double-layer insulation made of composition based on high-density polyethylene, armour bedding in the form of rubberized nonvulcanized fabric placed above cores, common armour manufactured from steel profiled band, and auxiliary insulation member made of at least two fluoroplastic tapes superposed on internal layer of insulation with 30-50 per cent overlapping. EFFECT: higher working capacity of cable under conditions of increased mechanical effects and ambient temperature. 1 dwg
