It uses composite insulated material, so it does not have pollution and explosion problems.

With particular advantages, it is suitable for some network where there is high switch frequency in the working current range or where repeatedly short circuit breaking operations happen.

VD4 type vacuum circuit breaker can be used as individual units for switchgear type KYN28, AMS, GZS1, ZS1,Unigear and so on.

Applied standards

 -GB1984 high voltage AC breaker
 GBT/11022 common technical specifications for high voltage switchgear and control gear standards
-DL/T403 12KV-40.5KV high voltage vacuum circuit breaker ordering technical specifications
-IEC62271-100 high voltage switchgear and control gear part 1: AC breaker
-IEC56 and similar standards in other main industrialized countries

Routine tests:

Our VTL series vacuum circuit breakers have passed the following routine tests before delivery from our factory:
mechanical performance test, main circuit power frequency withstand voltage tests, dielectric tests on auxiliary and control circuits,  main circuit  resistance test, interlock operation tests, mechanical operation tests, electric operation tests,ect.

Specifications

Embedded poles:

The embedded pole applied in our vacuum circuit breaker is developed and manufactured by us. Compared with

traditional assembled poles, embedded poles need much less accessories, conduct joints and fasteners. As a

result, the pole assembly process and the reliability of the main circuit is improved. The epoxy resin is used as

insulation medium.

It provides good insulation for the embedded vacuum interrupter and the conductive part of the main circuit. It can

protect the vacuum interrupter form the external environment influences, such as dust, moisture, small animals,

condensation and filth.
