FIELD: electricity.SUBSTANCE: cable includes at least one current-carrying conductor coated with insulation from polyvinylchloride compound and an external cover from polyvinylchloride compound, which differs by the fact that insulation and the external cover are made from polyvinylchloride compound containing suspended polyvinyl chloride 100, Calkyl phthalate plasticising agent 30-70, Calkyl-aryl phosphate plasticising agent 0-20, lead complex or CaZn-stabilising agent 5-9, phenolic antioxidant 0-0.5, epoxidated vegetable oil 0-5, antimony oxide 0-5, zinc oxide 2-10, zinc borate 0-10, finished aluminium or magnesium hydroxide, or their mixture 50-200, finished calcium carbonate, or calcium-magnesium carbonate, or their mixture 50-300, calcium or magnesium silicate 0-20. Additionally, the cable includes filler, belt insulation, which can be made from polyvinylchloride compound of reduced fire hazard, for example of Lousgran grade. In particular cases, the cable is provided with armour and shield.EFFECT: invention allows reducing corrosion activity of a cable and increasing fire resistance rating.8 cl, 1 dwg, 1 tbl |
