To contribute to the efficient generation of electric power and minimise loss, Mitsubishi Electric is taking active measures to save energy and reduce CO2 and other greenhouse gases with its diverse range of energy systems, including power generation systems, power transmission and distribution systems, and total solutions for energy saving in factories, commercial buildings and shops.
Mitsubishi Electric is a leading developer and manufacturer of power transmission and distribution systems on a global scale. Our high-voltage switchgears, transformers, protection & monitoring systems and power stabilization devices are core products in commercial and private utilities systems alike, and our control systems are installed to ensure stable operation that is both environment-conscious and highly efficient.
Mitsubishi Electric provides different kinds of protection relay which contains the necessary elements for the protection of extra high voltage power and transmission system and also distribution network facilities and devices such as transformers, generators, motors, GIS etc. In order to ensure the life and the operation condition of the power systems , monitoring system on the power equipment is very essential for the client so as to check the healthiness of their equipment based on the monitoring system. Client can understand equipment’s healthiness and make a plan of maintenance or replacement can be implemented in advance.
Mitsubishi Electric is a leading manufacturer of photovoltaic (PV) power systems worldwide. Our PV generation technology originates from our research on PV cells for satellites, which started back in 1974. In combination with our vast experience and accumulated know-how in power systems and semiconductor technology, we have developed photovoltaic systems designed for superior performance and unbeatable reliability. At Mitsubishi Electric, we integrate all of our PV product development and manufacturing operations at our own facilities in Japan. From cell research and production to the manufacturing of modules, we are able to take control in each step of the process. That is why we are fully confident in the highest quality of our products. Enjoy peace of mind for years to come with Mitsubishi Electric's photovoltaic systems.
The demand for fire-resistant, non-flammable electric equipment for urban use is increasing and Mitsubishi Electric manufactures highly reliable SF6-Gas insulated transformer by adopting the excellent insulating and non-flammable gas which is wide accepted on using in electrical equipment.
Mitsubishi Electric SF6-Gas insulated transformer are highly recommended for installation in cities and towns as underground substation where fire safety is of primary importance, in hydroelectric-power plants and water treatment plants where the water must be kept free of pollution, and in other plants where the operating reliability must be high.
Since the commencement for transformer production in Japan, Mitsubishi Electric has held a leading position in fields of large power transformer design and manufacture. Mitsubishi Electric transformers are manufactured on the basis of over 70 years of transformer manufacture and continuous research efforts toward improvement of the technical skills and materials have earned for these products a high reputation and wide acceptance.
The advantages of Mitsubishi Electric GIS are numerous including space savings, flexible layout designs, simple construction (e.g. short installation time), minimal maintenance, and excellent reliability and safety.
Type: HS-X-1 C-GIS(22kV), HS-X-A C-GIS (11kV) , HS-X-3 C-GIS (22kV/33kV)
Mitsubishi Electric has rich experience in developing switchgear panel, vacuum circuit breaker for the LV-MV distribution network since 1979 and cubicle GIC (C-GIS) is newly developed for the replacement of the traditional air-insulated switchgear panel to overcome the large capacity required by the client and improve the reliability.
Cubicle GIC (C-GIS) that is a switchgear panel operated in 11-33kV class distribution system includes circuit breaker, disconnector, earthing switch, current transformer and voltage transformer integrating into the cubicle panels.
Mitsubishi Electric developed the SF6 Gas insulated distribution transformers with an advantage of the non-flammable characteristics which are suitable for located at the indoor floors of the commercial building and residential building.
Since it is non-flammable electric equipment, the fire fighting systems are not required for this type transformer. The rating class is 6.6kV, 11kV and 22kV.
Type: MDT-HA, MDC-HA, MRD-HA. MBP-H1A, MFR-H1SA, MBP-H3SA
Mitsubishi Electric online partial discharge monitoring system can detect the partial discharge activity continuously and provide an alert in advance through its diagnosis before the insulation breakdown is happened during the GIS operation.
This monitoring system can also be used during the High voltage commissioning test recommended by CIGRE that can detect any potential insulation breakdown before in service.
