OREANDA-NEWS. May 12, 2016. Power transformers are electrical devices mainly located in power plants or electrical substations that support the efficient supply of electricity. Mitsubishi Electric manufactures both shell-type and core-type power transformers. Shell-type transformers allow for compact design, low energy losses and high seismic capacity due to their formfitting design.

The new 765kV transformer uses a shell-type design to compactly contain the iron core, winding and insulator, realizing a 765kV voltage capacity and a 750 MVA rating.

The Power Transformer Division of MEPPI started operations in April 2013. Leveraging its experience and expertise in supplying shell-type 500kV and 345kV 1-phase power transformers to the North American market, MEPPI was able to realize this new high-capacity 765kV power transformer.

Looking forward, Mitsubishi Electric will further expand its highly reliable power transformer business to contribute to safe power distribution in North America.
