充分満足するものとは言い難い。In the case of electrically insulating members such as busbars, insulating busbars, and thyristor stacks, which are made by molding resin around a conductor, the mold resin may If cracks occur in the core member, the mechanical strength of the core member may decrease.For this reason, in order to alleviate the interfacial stress between the mold resin and the conductor, the surface of the embedded conductor in contact with the mold resin is made flexible. Although sheet-like fiber base materials treated with resin have been rolled or coated with silicone grease, they have not been able to provide sufficient stress relief, and the quality has been poor in terms of stability. It's hard to say that I'm satisfied.

化されている。A heat-shrinkable tube is inserted into a copper rod, and the tube is heat-shrinked using a heating furnace or a dryer to form a covered conductor, and then a thermosetting resin (epoxy resin) is applied to cover the heat-shrinkable material of the covered conductor. , unsaturated polyester resin, etc.)
At this time, the heat-shrinkable material and the copper rod are in close contact with each other, but they are not integrally bonded together. Also, the molding resin is bonded and integrated with the heat-shrinkable material. .

うに耐クラツク性に優れた電気絶縁用部材を提供する。Since the present invention is constructed as described above, the heat-shrinkable chain attached to the metal conductor and the conductor can move freely in the axial direction, and within the range of rubber-like elasticity in the radial direction. 〇Also, because the mold resin and the heat-shrinkable material are bonded well, the stress dispersion effect can be obtained even against external forces, and the crack resistance is significantly improved due to the effect of relieving internal and external stress. can be improved. Furthermore, by making the heat-shrinkable material conductive, potential partial discharge between the multimetallic conductor and the molded resin can be prevented.The present invention thus provides an electrically insulating member with excellent crack resistance.
