The invention relates to a medium-voltage fire-resistant power cable, which belongs to the technical field of cables. The cable comprises a cable material and a wire material. The cable material includes the following raw materials in parts by weight: 60-80 parts of modified nitrile rubber, 30- parts of high-density polyethylene resin 40 parts, 20-30 parts of low density polyethylene resin, 10-20 parts of modified mica powder, 1-3 parts of DCP, 2-4 parts of dioctyl phthalate, 1-3 parts of vinyl silane, antioxidant 0.8-1.2 parts of DLTP, 0.5-1.5 parts of sodium salicylate, 0.6-0.8 parts of organotin stabilizer and 80-100 parts of deionized water; adding mica powder in the formula of the present invention can improve the phase between the resin and the resin. Capacitance, but also can greatly improve the insulation performance of the resin, heat aging resistance, UV aging resistance, and improve the wear resistance of the material. |
