72.5/126/145kv Gis

These 72.5/126/145kV GIS is a newly developed smart high voltage switchgear equipment. It is composed of inlet/outlet bushing (BSG), disconnector switch (DS), earthing switch (ES), circuit breaker
(CB), and current transformer (CT), etc. Fast earthing switch (FES), potential transformer (PT), and lightening arrestor (LA) and be added as per the needs of the customer. HGIS features compact structure,
less area needed, less site erection, short erection lead time, highly operational, highly intelligent, and fewer needs for maintenance, etc.
1a Three phases located in different enclosures,few inter phase interference. Phase width is 0.65m.The shell is all aluminum structure which is light weighted, good conductivity, and no eddy loss.
2a Outstanding Breaking Capacity of the Circuit Breaker
The circuit breaker adopts the principle of arc distinction by self power, which sufficiently uses the arching energy. The arc distinction capacity has been improved, less operation movements for the mechanism, and much better reliability.
3a Highly Reliable Operation Mechanism
The circuit breaker adopts CT30 spring operation mechanism which has fewer movements,demands less maintenance. The three phases are mechanically interlocked and can reach highly and reliable synchronization.
