The existing conductive rod support structure is as in the Chinese patent CN2884445Y discloses "three-column insulators for high-voltage gas-insulated busbars". The three-column insulator in this document is the supporting structure of the conductive rod. The three-column insulator includes a tubular base body, and at least three Insulating pillars, the top of each insulating pillar is provided with a cylinder connecting structure for connecting with the cylinder. The problem with the existing supporting structure of conductive rods is that the base body and the insulating supports are integrally arranged, and the base body and the insulating supports form a structure with a very irregular shape. The manufacturing process of this irregularly shaped integral structure is very difficult. Complicated, difficult to manufacture, and high in production cost; in addition, since the base body and insulating pillars are integrated, this requires that the base body must also be made of insulating materials, and in order to realize the electrical connection of the corresponding conductive rods, it is also necessary to set some other conductive structures on the base body , the setting of this conductive structure increases the structural complexity of the supporting structure of the conductive rod.
