Low Temperature Resistant Material Study of Fitting in Power Transmission Line
Establishing large coal fired power, hydropower and wind power bases in the energy resources centre and large capacity long distance power energy transmission are main way to solve resource contradiction according to distribution characteristic of energy resource in our country. Power transmission line shall avoid influence of high altitude and low temperature etc environments in long distance power transmission, such as western area, the steel material of the fitting in the line with low temperature requirement shall have good low temperature resistant brittle, therefore the fittings in the power line are requested to have good low temperature resistant comprehensive performance. In combination with application environment of the power fittings and characteristics of metal material, carry out analysis on possibility of application of the low temperature resistant material in the fittings in the power line from performance requirements, fitting materials, geometrical features of the fittings, test characteristics of the fitting etc.
