Abstract

The invention relates to an insulating tube type busbar and a manufacturing method thereof in the technical field of high voltage distribution. The insulating tube type busbar comprises: an insulatingtube type busbar conductor, an internal conductive pipe or a plurality of leads, radiating holes, radiating spaces inside the pipe and end plate open pores, wherein the insulating tube type busbar conductor is arranged at the outermost layer and is internally provided with the internal conductive pipe; and the end part of the insulating tube type busbar conductor is provided with the radiating holes. By utilizing the hollow insulating tube type busbar conductor, a conductor is added in the insulating tube type busbar conductor, the hollow conductor of the insulating tube type busbar is internally stuffed with the conductive pipe, or a plurality of corresponding leads and presses the end part thereof into a whole; radiating and temperature reduction measures are taken, and the end part ofthe insulating busbar is provided with radiating holes, therefore, the current-carrying capacity can be increased without increasing the external diameter size of the busbar, thus reducing the using amount of insulation materials and lowering cost.

Description

technical field [0001] The invention relates to an insulated wire in the technical field of high-voltage power distribution and a processing method thereof, in particular to an insulating tubular busbar and a processing method thereof. Background technique [0002] In AC power distribution devices below 35KV, more and more tubular insulated busbars are used to transmit power. The cross-section and diameter of the tubular bus conductor are determined according to the magnitude of the current. Due to the skin effect, the wall thickness of the conductive tube cannot be increased indefinitely. Therefore, under a certain voltage, the larger the current, the larger the diameter of the tubular insulating busbar, and the corresponding increase in insulating materials, and the more supporting accessories. Therefore, even if the voltage is constant, the greater the current, the insulation cost and accessory cost of the tubular insulated busbar will increase greatly, which is obviousl...
