33kv/72.5kv/145kv 50Hz/60Hz Outdoor Hgis Compact Easy Gas Insulated Switchgear Combined of CB Ds CT PT

The high voltage part is mounted in the front section of the trailer to provide a relatively spacious inlet space and bigger ground insulation distance.The high voltage switch adopts our in-house developed HGIS,which is an intergration of tank SF6 gas circuit breaker(CB),disconnector switch(DS),earthing switch(ES),fast earthing switch(FES),current transformer(CT)and inlet/outlet bushing(BSG),etc.In addition,the high voltage part is also equipped with independent type potential transformer(PT)and lightening arrestor(LA),etc.
