Problems solved by technology

Special solar cables (ie photovoltaic cables) must be used in solar equipment, otherwise it will affect the service life of the entire system
Solar energy systems are often in harsh environmental conditions. If ordinary cables are used in this environment, the cable sheath will be easily broken and lead to degradation and failure of the insulation layer, which will directly increase the loss of the cable system, cause a short circuit of the cable, and even cause a fire. or personal injury

Abstract

The invention relates to a special cable for a photovoltaic system with high lifespan, ultraviolet resistance and corrosion resistance. The sheath of the special cable for the photovoltaic system is prepared from the following materials and raw materials for preparing the sheath in parts by weight: 100 parts by weight of ethylene-ethyl acrylate copolymer, 10-30 parts by weight of polyolefin resin, 2-10 parts by weight of graphene-ethylene-ethyl acrylate copolymer blend, 1-15 parts by weight of maleic anhydride grafted SEBS, 5-20 parts by weight of oxidized polyethylene wax, 5-15 parts by weight of calcium-zinc composite stabilizer, 5-60 parts by weight of filler; the mass ratio of graphene and ethylene-ethyl acrylate copolymer in the described graphene-ethylene-ethyl acrylate copolymer blend is 1: 5‑100. The photovoltaic cable of the invention has very good anti-ultraviolet and corrosion-resistant properties.

Description

technical field [0001] The invention relates to a special cable for a photovoltaic system with high lifespan, ultraviolet resistance and corrosion resistance. Background technique [0002] Since the large-scale use of mineral energy by humans, especially the development of petroleum resources, human production and life have undergone tremendous changes. The ills of coal-based energy structures in many countries in the world. Especially since the oil crisis in the 1970s, people have gradually awakened to the fact that when mineral energy is eventually exhausted, human beings must develop new energy sources, especially renewable energy sources, in order to maintain their own production and life. Compared with traditional energy sources, new energy sources generally have the characteristics of less pollution and large reserves, which are of great significance for solving the serious environmental pollution problems and the depletion of resources (especially fossil energy) in t...
