Gas Insulated Switchgear ( GIS) 1000Kv

Back

Modular design which can according to users requirement
Adopt separate units as well as dismantling or assembling flexibility
The CB adopt double-break structure which also can continuously interrupt rated short-circuit current of 50kA 16times without any maintenance
The circuit breaker installed with resistors in parallel per phase as well as mounted with parallel capacitor. Each phase also equipped with a hydraulic operating mechanism which can satisfy very strictly requirement
The DS and ES can be directly connected to the busbar or other units separately
The mechanism can be operated by the motor operating mechanism, or by the manual hand
Lightweight enclosures of aluminum with good conductivity, no eddy-current losses and a high resistance to corrosion
Short erection times and high reliability, by providing large transport units assembled and tested in the factory
