Weather-proof cable material for wind turbine generator

Abstract

The invention discloses a weather-proof cable material for a wind turbine generator. The weather-proof cable material comprises raw materials in parts by weight as follows: 15-35 parts of nitrile silicone rubber, 20-30 parts of an ethylene-propylene alpha-olefin copolymer, 1-4 parts of a maleic anhydride grafted ethylene-vinyl acetate copolymer, 10-30 parts of nylon modified low-density polyethylene, 2-4 parts of N,N-diisopropylaniline, 10-20 parts of nano-silica, 10-20 parts of kaolin, 20-40 parts of modified rice protein, 40-60 parts of nano calcium carbonate, 5-15 parts of ammonium polyphosphate, 1-2 parts of 4,4'-diaminodicyclohexyl methane, 1-2 parts of bis(tert-butyl dicumyl peroxide), 0.2-0.8 parts of gamma-glycidoxypropyl trimethoxysilane, 1-2 parts of dibenzoyl peroxide, 0.5-1.2 parts of ethylene dimethacrylate, 1-2 parts of 2,6-di-tert-butyl-4-methylphenol, 1-5 parts of melamine pyrophosphate, 2-5 parts of melamine cyanurate and 2-4 parts of a lubricant. The weather-proof cable material has excellent thermal stability and mechanical properties as well as excellent corrosion resistance and ageing resistance.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a weather-resistant cable material for wind turbine generators. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. China's wind energy reserves are large and widely distributed. According to the national plan, the national wind power installed capacity will reach 20-30 million kilowatts in the next 15 years. Judging from the growth of global wind power generation in the past two years, wind turbine generators may grow at a rate of more than 50% in the next few years. These conditions show that there is a space for vigorous development and promotion of wind power generation, and it is matched with wind power projects. There is a huge market demand for special cables used in wind turbine generators. Wind power generation projects are carried out in the open air, and the service ...

AI Technical Summary

Problems solved by technology

Wind power generation projects are carried out in the open air, and the service life of the fan is required to be very long. This requires extremely high aging resistance performance of the wind turbine generator cable material in extreme environments. Ordinary cable materials contain more inorganic materials, while rubber Less content, poor crack resistance, low safety performance, and short service life of the cable
