For over 95 years, Mitsubishi Electric has provided power transformers for energy transmission and distribution systems throughout the world.
We manufacture both shell-form and core-form design and have chosen to supply shell-form transformer designs for high voltage and/or large capacity applications. The approximate transition point between the core-form range and shell-form range is 200 MVA bank capacity, and 275 kV high voltage winding rating. All supplied transformers above this transition point adopt the shell-form design because of the inherent advantages of the shell-form design for high voltage, large capacity applications.
