Outline

This equipment is indoor metal armoring with drawable switchgear (hereafter refer to as switchgear. 3.6-12kilovolt three  phase AC 50Hz single bus bar and the single bus bar subsection system's omplete electricity distribution equipment is used in the  power plant, small and medium-sized generator power transmission, industry and mining business power distribution as well as  electrical industry system's second transformer substation's electric take-over , power transmission and large-scale high pressure  motor starting and so on. The purpose is to control, protect and monitor. This switch equipment is up to the standard of IEC298、 GB3906 and can prevent the charge from pushing and pulling the breaker, from opening and closing the breaker, from insulation  with electricity by mistaken, from earthed switch closing the breaker ,from opening the switch's interlock when it with electricity  mistakenly. It can not only use with VS1 vacuum circuit-breaker, but with ABB Corporation's VD4 vacuum circuit-breaker. It is indeed  a kind of power distribution equipment with superior performance.
