Summary:The invention discloses a method for improving voltage resistance of an insulating layer of a coaxial cable. The method comprises the following steps: step 1, preparing materials; step 2, wrapping an insulating layer; 3, wrapping an outer conductor; 4, wrapping a protective layer; step 5, thermal shrinkage curing; step 6, quality inspection; in the first step, the inner conductor is made of a pure aluminum rod, the insulating layer is made of a polyimide adhesive tape, a polypropylene film and a polyimide film, the outer conductor is made of aluminum foil, and the protective layer is made of a polyimide film and a polypropylene film. According to the invention, the insulating layer is formed by mixing and wrapping the polyimide adhesive tape, the polypropylene film and the polyimide film, so that the voltage endurance capability of the coaxial cable can be effectively improved and can reach 100KV/mm; according to the invention, by optimizing the number of wrapping layers of the polyimide adhesive tape and the
