This kind of product is a new generation of 40.5KV mechanism developed on the
basis of CT19B machanism, CT19BN-1 mechanism is available for outdoor 35 KV
vacuum HV breaker. It has output way of pulling up and down. The output angle of
this institution is from 50 °to 55 °, and mechanical life is 10000
times.
