Keterangan :

Mitsubishi Electric gas-insulated switchgear ( GIS) and gas circuit breakers ( GCB) represent the best of modern technologies. Since commercializing Japan' s first GCB in 1968, we have supplied a variety of circuit breakers and GIS rated from 72~ 1100kV.

• Gas-insulated Switchgear ( GIS)
The advantages of Mitsubishi Electric GIS are numerous including space savings, flexible designs, less field construction work ( i.e., quicker installation time) , minimal maintenance, and excellent reliability and safety.

• Hybrid Gas-insulated Substation ( H-GIS)
Incorporating some of the latest technologies, our H-GIS are now smaller and more modular. As a result, the time required for updating GIS to be shortened.

• Gas Circuit Breakers ( GCB)
Gas circuit breakers incorporated some of the latest technologies including thermal gas current analysis, which contributes to ensuring excellent product reliability.

• Generator Main Circuit Breakers ( GMCB)
The GMCB is the primary circuit in power plants. Efforts are being made to modularize the circuit breakers, isolators and grounding switches with the aim of manufacturing smaller, more lightweight devices.

• Lightning Arresters
Mitsubishi Electric produces various types of lighting arresters, such as the 500kV insulator-type for transformers.
