关键词: 电阻温度系数, 新型节能导线, 高温油浴试验台, 温度控制

Abstract: In this paper, high-temperature oil-bath test bench for temperature coefficients of conductor resistance, which can increase conductor temperature by oil bath, has been designed. The test bench can eliminate the temperature difference between inside and outside and control the conductor temperature accurately, with which the tests for temperature coefficients of the new types of energy-saving conductors, such as high conductivity aluminum conductor steel reinforced, high conductivity aluminum conductor aluminum alloy reinforced and medium strength all aluminum alloy conductor, have been carried out to provide guidance for the engineering design.

Key words: temperature coefficient of resistance, high temperature oil bath test bench for conductor temperature coefficient of resistance, temperature control
