Gas-insulated C-GIS is an underground multi-circuit breaker that protects distribution lines by minimizing power failure and power failure time as a power device for substations and power plants. It is available in two types:single bus and double bus lines.

C-GIS used for 25.8kV transmission/distribution AC circuit has a structure that is safe for operation and maintenance by embedding all live wires in a cubicle tank filled with SF6 gas,and a vacuum cut-off part (V,I) with excellent extinguishing capability is applied to the cut-off part. Thus,the electrical performance of E2 Class has been achieved.

The operating device of the cut-off part uses a P.M.A (Parmanent Magnetic Actuator),which is guaranteed to operate more than 10,000 times,has superior durability compared to the existing spring method,and realizes uninterrupted conversion by making ALTS conversion time within 1 cycle.

safety

-Safe pressure release on operator and equipment when abnormal internal pressure occurs

-Equipped with breaker trip-free function and interlock function for each component

-Breaker trip possible when external power is lost

-Prevention of deformation of parts by providing Bellows for cushioning between panels

responsibility

-Stable operation is implemented by using a magnetic actuator that is guaranteed to operate more than 10,000 times as the main cut-off part.

-VI (Vacuum Interrupter) E2 level electrical life realization

Other technical notes

-Easy to replace and interchange parts by adopting the same parts module for each panel

-Convenient maintenance due to the structure of separate in-tool for each panel

-Reduced installation area to 70% compared to the existing MCSG
