Indoor HV Earthing Switch

General:

Indoor high voltage(HV)earthing switch absorbs advanced new technical from domestic and abroad. It confirms to GB1985-2004 <ACHV DISCONNECT SWITCH AND EARTH SWITCH>standard. And applies to three-phase rated voltage 405kV. AC50/60Hzpower system. It can support the use of KYN61-405HV switch panel and other models, the foundation is protect the HV electric equipment when repair or maintenance.
