Difference between embedded pole and traditional insulating
Embedded pole embeds the conductive parts related to the vacuum arcing chamber and circuit breaker into the epoxy resin, which is a kind of solid insulation material that is easy to cure. Epoxy resin is poured on the outside for encapsulation, and the pole column is sealed to form an integral part of the whole circuit breaker pole column.

Structure and working principle of HV vacuum load break switch
High voltage vacuum load switch uses vacuum interrupter as arc extinguishing device. The interrupter is the heart of the high voltage switch. When the moving contact and the fixed contact of the switch are separated, under the action of high electric field, the medium particles around the contact are ionized, thermally dissociated and collided dissociated,
