Abstract

The invention is suitable for the technical field of photovoltaic cables, and provides a photovoltaic cable and a preparation method and application thereof, and the photovoltaic cable comprises a cable core which is composed of a plurality of conductors which are interwoven, wound and bundled; the outer side of the cable core is coated with the insulating layer; the outer side of the insulating layer is coated with the wear-resistant layer; the cable comprises a cable core, a wear-resistant layer and a protective layer, the wear-resistant layer wraps the outer side of the cable core, the insulating layer wraps the outer side of the cable core, it can be guaranteed that the phenomenon of electric leakage does not occur when the multiple conductors convey current, normal work of the multiple conductors is effectively guaranteed, meanwhile, the wear-resistant layer and the protective layer sequentially wrap the outer side of the insulating layer, and the service life of the cable core is prolonged. According to the photovoltaic cable, the insulating layer and the cable core in the insulating layer can be effectively protected, the phenomena of scratching and cracking are prevented, the overall working life and the service life of the photovoltaic cable are prolonged, and the overall structural strength of the photovoltaic cable is improved.
