Analysis Of The Traditional Shapes Of Epoxy Resin Insulator Cap Structures In China

In many domestic power distribution and transmission equipment, the cap brim of type high voltage epoxy uses a traditional structural form, mostly employing a cylindrical head design with a relatively small head size.

The cap brim structure of type epoxy resin insulator is characterized by a more compact head, lighter weight, higher overall strength, and electrical creepage distance meeting design requirements.

The cap brim structure is typically integrated with the main body of type high voltage epoxy resin via a sleeve-type connection, using metal flanges or hardware assemblies for connection to the tower body or conductor hardware.

To accommodate the mechanical and electrical connection requirements between the epoxy resin insulating core and external hardware, the cap brim design of type high voltage standoff maintains a simple structure and rounded shape, with fewer connection nodes and clear force transmission. This reduces stress concentration and promotes long-term stable operation.
