Description

EK6-12/40.5kv Indoor AC High Voltage Earthing Switch A-B-B Grounding 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.

2. Normal Using Ambient Conditions
(a) ambient air temperature: upper limit +40℃;lower limit – 25℃
Remark: allow to store and transport under – 30℃
(b) altitude limit: under 1000m
(c) relative humidity: under 90%
(d) earthquake intensity : not higher than class Ⅷ
(e)the place should be without fire,explode danger, serious dust, chemical corrosion and strong shork.
