Dry type composite capacitive type sleeve

The utility model relates to a dry composite capacitance casing tube, which can be widely used for indoor and outdoor high-tension transformation equipment, and comprises a flange, a capacitance core, a conduit, an insulating layer, an umbrella skirt and a connection survey terminal which are connected together. The utility model is characterized in that the both ends of the conduit of the capacitance core are respectively and fixedly embedded with a metal awl, the oblique planes of the metal awls are wrapped in the insulating layer, the flange and the capacitance core are fixedly connected with nuts through snap rings, and the external surface of the flange is fixedly connected with a high-frequency seat. The utility model enhances the partial discharge performance of products, improves pressure distribution, enhances the bending property of products, and puts an end to pole plate slip. The utility model has the advantages of simple structure and convenient operation.
