HV Substations
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.
Mitsubishi Electric began its industry leadership in Gas Insulated Switchgear (GIS) by building its first product in 1968. In 1973, it installed the first 500kV hybrid gas-insulated substation. Three years later Mitsubishi Electric constructed the world’s first 550kV fully gas-insulated switchyard at the Ohi Nuclear Power Station, which is the largest nuclear power plant in Japan. Since then more than 12,000 GIS bays over the range of voltages manufactured have been installed in substations worldwide.
As Mitsubishi Electric Europe we combine the Japanese strengths of equipment development, manufacturing and quality control with the traditional British skills of innovative engineering design, project management and international construction to maintain our lead in the provision of turnkey services with a strong customer focus. Taking this a step further, we take the view and opinions of our customers very seriously. We believe that maintaining good working relationships throughout the life of a project, and into post project support, is of vital importance.
