Embedded Pole for Disconnector

Epoxy embedded poles, or called embedded vacuum interrupters, vacuum interrupters with epoxy resin, is made by casting vacuum interrupters, main circuit conduct and mounting parts with epoxy into an integral part.  

The main advantages of this technology (compared to an assembled or open pole system) are its high dielectric strength as well as better protection against environmental influences. Embed the vacuum interrupter in resin make the pole particularly sturdy and protect the interrupter from impacts, dust deposits and humidity. The design is compact, robust and modular. Another important advantage is the fast and easy assembly of the pretested and adjusted poles on the vacuum circuit breakers. 

JOYELECTRIC Embedded Pole's Production and Quality Control Process

Warehouse→Circuit resistance and withstand voltage test →Vacuum interrupter soft packing→Soft packing test→Upper outlet assembly→Circuit resistance test→Embedded pole shaped→Embedded pole test→Secondary solidification→Embedded pole appearance inspection→Secondary wire assembly→Circuit resistance and withstand voltage test→Surface treatment→Finished product inspection→Finished product packing

Our embedded poles are used on vacuum circuit breaker, disconnector and fuse, etc.
