Description

technical field [0001] The invention relates to a high-voltage insulated bus connection structure, which belongs to the technical field of electric equipment. Background technique [0002] The high-voltage insulating busbar is usually used for the transmission of high-voltage electricity. The high-voltage insulating busbar is composed of a conductive core and a shielding layer. The shielding layer is composed of insulating layers, conductive or semi-conductive layers that are alternately coated on the outside of the conductive core. The conductive core usually adopts a conductive metal tube, such as a copper tube. [0003] The insulating layer of the shielding layer is mostly made of fibers impregnated with epoxy resin or organic insulating film tapes, and the conductive or semiconductive layer is directly made of conductive or semiconductive materials.
