Abstract
The paper focus on the influence of the deviation of material thermal resistance coefficient on the conductor temperature calculations, based on the three-core cable thermal circuit model. Meanwhile we also design a temperature rise test of the 10kv three-core cable in step current, measuring the temperature of the cable structure in different steady state. Then we calculate the thermal resistance of the cable body and the thermal resistance of the layer material , find the change law of the thermal resistance with the temperature and analyses the effect of the dynamic characteristic of the material thermal resistance on the conductor temperature calculations in the three-core cable thermal circuit model.
