363kV series T·GCB/GIS/HGIS
Two kinds of 363kVT·GCB:single break and doublebreak structure,of which single break T· GCB may break short circuit rated current and duration of 50kA/3s while double break TGCB may break short circuit rated current and duration of 50kA/3s or 63kA/3s.There is a parallel capacitor between breaks on 363kV 63kA double break product,closing resistance may be added according to user's requirement.
1 .Circuit breakerwith reasonable design,high reliability,simply structure and long-term overhaul
2 .Performance and parameters satisfied GB1984,IEC62271-100 and technical documents.All type tests passed according to national standard and IEC standard.
3.363kVT·GCB may operate under extreme lowtemperature below-40ºC.Successfully operated in high altitude,low temperature area as Qinghai Province.






2. The same structure as 363kVT·GCB is adopted on the circuit breaker.There are horizontal and vertical arrangements;
3.Compact structure and reduced footprint in circuit breaker stand arrangement;whole bay transport and short period of site installation and commissioning
4. Circuit breaker is provided with hydraulic or pneumatic operating mechanism
5. provided with motor spring operation mechanism
6 Mechanisms of disconnector and earthing switch are three-pole ganged operated straightly with body.
6. Spacer with metal loop is adopted.
7. Modular arrangement is adopted to meet requirements of various main wiring
8. Minimum distance between centers oftwo bays is 2600mm while distance between phases is 800mm.The product is small in volume and compact in structure as well as reduced area occupied
