Problems solved by technology

The patent sets up different functions in layers, such as insulation, corrosion resistance and wear resistance, which are arranged sequentially from the inside to the outside. With the increase of use time, the damage of the outer layer will lead to the weakening or even disappearing of the outer layer, which seriously affects the use of the product. Life, in addition, layered settings also increase the difficulty of the process

Abstract

The invention provides a photovoltaic cable and a preparation method, wherein the outer surface of a conductor wire core is directly extruded and cladded with a rubber compound to form a protective layer so as to obtain the product. According to the invention, the main materials of the photovoltaic cable comprise an ethylene-vinyl acetate copolymer, an acrylonitrile-butadiene-styrene copolymer, anitrile silicone rubber and a chlorosulfonated polyethylene rubber, organic modified mixed powder is obtained by mixing hetian jade powder, Liuhuan stone powder, boron nitride powder, nano zinc acrylate, sepiolite powder and the like and then carrying out organic modification, complex layered extrusion cladding is avoided, the process is simple, and the obtained photovoltaic cable has good mechanical properties, flame retardance, high-temperature resistance, low-temperature resistance and weather resistance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a photovoltaic cable and a preparation method. Background technique [0002] With the enhancement of human awareness of environmental protection, the world's energy structure is also undergoing tremendous changes, that is, the transition from a fossil energy system to a sustainable new energy system based on renewable energy. From the perspective of various renewable energy resources in the world and in my country, solar energy is the most important energy resource. Therefore, solar power generation should be the main force in providing large-scale power generation in the future, and it is one of the directions of large-scale development. Most solar energy companies are implementing the photovoltaic power generation model, and photovoltaic power generation is one of the fastest growing enterprises in the world. With the rapid development of the photovoltaic industry, the market d...
