High-efficiency energy-saving medium-voltage fireproof cable

Abstract

The utility model provides a high-efficiency energy-saving type medium-voltage fireproof cable, which relates to the technical field of cables and comprises a bottom plate and a medium-voltage cable body, the medium-voltage cable body comprises an outer sheath and a cell conductor, the inner wall of the outer sheath is connected with a fireproof isolation sleeve, the inner wall of the fireproof isolation sleeve is connected with a sealing sheath, and the sealing sheath is connected with the outer sheath. The inner wall of the sealing sheath is connected with a high-temperature-resistant layer, the outer wall of the cell conductor is sleeved with a shielding layer, and the outer side of the shielding layer is sleeved with a flame-retardant layer. According to the utility model, the fireproof isolation sleeve is made of a non-combustible polyurethane material and has relatively high fireproof isolation performance, the sealing sheath is made of silicone rubber and has relatively good weather resistance and heat resistance, and the high-temperature-resistant layer is made of fluororubber and can keep good cable performance in a high-temperature environment and provide high-temperature-resistant protection; and the flame-retardant layer is made of a flame-retardant polyvinyl chloride material, has good flame-retardant performance, can inhibit flame spreading and smoke generation when a fire disaster occurs, and has a fireproof protection effect.
