Conductor-to-ground Insulation Structure In Epoxy Resin Bushing

epoxy bushing manufacturer is typically manufactured using epoxy resin composite materials through a mold casting process. The resin material is thermosetting, forming a continuous insulating layer around the conductor. Standard-designed geometry allows for adjustment of the electrical stress distribution, ensuring controlled electric field distribution along the surface and internally, reducing the risk of localized electric field distortion.

Compared to traditional ceramic or oil-impregnated bushings, epoxy bushing for transformer offers greater structural flexibility. The conductor diameter, insulation wall thickness, and external geometry can be adjusted according to system design. The dielectric properties of the material itself and the manufacturing process determine the stability of its insulation performance, providing continuous dielectric isolation for the conductor from one potential region to another.
