EK6-12/40.5kv Indoor AC High Voltage Earthing Switch

1.Product introduction
Earthing switches of series EK6 are determined for indoor in stallation and conform to the requirements of 
GB1985 and IEC 62271-102. They are fitted with snap-action operating mechanisms for positive high-speed 
closing and sufficiently dimensioned to conduct the rated short-circuit making current when closed under load. 
The speed of the snap-action closing operation is independent controls. The earthing switches are supplied 
as kits with a pre-assem bled active part and correspon ding earthing con tacts supplied loose. Correct in 
stallation of these parts in a switchgear panel results in a functioning earthing switch. Routine tests toGB1985 
and IEC 62271-102 are to be carried out at site accordingly.
