The utility model relates to the technical field of BOPP (biaxially-oriented polypropylene) electrical films, and provides a BOPP electrical film with a multilayer composite structure, which comprises an electrical film main body, a winding main body and a polypropylene film main body, the middle of the electrical film main body is fixedly connected with a film body reel body, and the inside of the electrical film main body is fixedly connected with an outer anti-slip layer. Through the double-sided design of the anti-skid layer on the outer side, when the film body is wound, the main body of the electrical film is not easy to fall off by utilizing the anti-skid characteristic and the tension of the film body, the anti-traction capability of the film body can be improved by the arranged strength reinforcing layer, and meanwhile, the high-temperature resistance of the film body is improved by the arranged heat-resistant layer; the anti-corrosion layer can cope with a special wrapping environment, during windin
