Product Description

1.General description
VACG30-12 indoor AC M.V. rotary disconnecting switch is a new type switch added rotary knife,the main structure is in tri-phase chassis,two plane,fixed two sets of insulator and contact,through the rotary knife,so as to realize the switch closing and opening. The VACG30-12D switch is in the VACG30-12 switch based on the increased with a grounding knife type,can meet the needs of different power systems,its performance conforms to GB1985-2004 AC M.V. Disconnecting Switch and Earthing Switch,used to connect and transfer line voltage without load,it is applied in power system of indoor 12kv and tri-phase AC 50Hz,rated current of 400,630,1000,1250A.And supporting the use of M.V. switchgear,also can be used separately.
