Problems solved by technology

The withstand power of the cable is linearly related to the difference between the maximum temperature of the inner conductor and the ambient temperature, and the maximum working temperature of the inner conductor is limited by the cable insulation material. The long-term working temperature of the cable insulation material is the maximum allowable working temperature of the inner conductor, but at present Most of the cable materials on the market do not have excellent high temperature resistance and cannot meet the needs of current high-power equipment

Abstract

The invention discloses a water-resistant cold-resistant cable material for large power. The water-resistant cold-resistant cable material is prepared from 3-5 parts of nanometer calcium carbonate, 40-60 parts of butadiene styrene rubber, 10-15 parts of high wear resistant carbon black, 3-5 parts of pentaerythritol, 10-13 parts of N330 carbon black, 1-2 parts of an antiager ODA, 3-4 parts of an ethene-methacrylate copolymer, 2-3 parts of melamine, 2-4 parts of zinc stearate, 4-6 parts of tert-butyl peroxybenzoate, 3-5 parts of sodium polyacrylate, 2-5 parts of butyl acrylate, 1-3 parts of zinc phosphate, 3-4 parts of ferrocene and 8-12 parts of a filler. The water-resistant cold-resistant cable material has excellent performances. Through use of butyl acrylate, product water resistance is improved, cable material internal plasticity is improved, a brittleness temperature is reduced and good cold resistance is obtained.

Description

technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power water-resistant and cold-resistant cable material and a preparation method thereof. Background technique [0002] With the development of my country's economy and the rapid development of the communication industry, more and more high-power equipment is used, which puts forward higher requirements for the performance of cables. The withstand power of the cable is linearly related to the difference between the maximum temperature of the inner conductor and the ambient temperature, and the maximum working temperature of the inner conductor is limited by the cable insulation material. The long-term working temperature of the cable insulation material is the maximum allowable working temperature of the inner conductor, but at present Most of the cable materials on the market do not have excellent high temperature resistance and cannot meet the needs of curre...
