Abstract：To ensure the quality and running-reliability, it’s essential to calculate the structural parameters of different kinds of the insulated tubular bus-bar. The design principle and factors which can influence the structure performance were analyzed in the paper, taking the 10kV/4 000A resin-impregnated-paper insulated tubular busbar for example. The electric field and temperature distribution of the straight body, curving body and the joint part were studied based on the finite element method. The relation of the important design parameters, such as the diameter and thickness of the insulated tubular bus-bar, the number of the shield layer, thickness of the insulation, impacting on the structure performance were also studied, which is important for the structure-optimizing research.
