system, and large scale voltage motor starting etc, so as to perform control protection
and monitoring. This switchgear complies with IEC298 and GB3906-91 etc standards,
in addition to work with domestically produced Model VH3 / VH4 vacuum circuit
breaker and VHCR series of VAcuum contactors provided, it may also work with
Siemens Model 3AH5 vacuum circuit breaker, and is really a power distribution
unit with superior performance.

Structure of cabinet body:
The switchgear is cladding type metal enclosed structure, consists of cabinet body
and with drawable part (midship handcart). Cabinet body is divided into handcart
room, main bus bar room, cable vault and relay instrument room. Three high voltage
compartments have pressure release passages and release ports respectively,
so that internal troubleshooting could be released only through release port
in case of failure, titus prevent fire pooling accident and protect personal
