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 high-mechanical-performance cable material for high power and a preparation method thereof. The high-mechanical-performance cable material comprises, by weight, 2-3 parts of stearic acid, 2-4 parts of activated magnesium hydrate, 3-5 parts of silicon dioxide powder, 2-3 parts of pyrophyllite powder, 3-5 parts of tris(2-ethylhexyl) phosphate, 2-4 parts of talcum powder, 45-65 parts of ethylene propylene diene monomer, 1-3 parts of 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol, 1-2 parts of antioxidant TPP, 15-20 parts of linear low-density polyethylene, 3-5 parts of 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, 2-4 parts of sodium sulfonate, 2-4 parts of polycarbonate, 2-3 parts of m-xylylenediamine and 8-12 parts of filler. The high-mechanical-performance cable material has the excellent heat-resisting sublimability, launderability, gas fading resistance, mechanical performance retainability, and the added2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol and antioxidant TPP are used together to achieve a remarkable synergistic effect.
Description
technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power cable material with high mechanical performance 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 current...
