About the company

Hitachi T&D Solutions, Inc. is a premier international supplier of electrical equipment including dead tank high-voltage circuit breakers, gas-insulated switchgear, transformers, and generator main circuit breakers. One of the company's recent accomplishments is the creation of the industry's first environmentally conscious high voltage vacuum circuit breaker, a 72.5kV dry air insulated solution that eliminates SF6 gas. It provides exceptionally low maintenance and operation costs, and poses no threat to the environment as the insulating dry air can be released into the atmosphere with no adverse consequences. Hitachi T&D Solutions, Inc. is dedicated to continuing the expansion and integration of its present products while developing new and improved product solutions to meet future energy demands.

Power Transformers >200MVA

Hitachi’s Kokubu factory located in Hitachi City, Japan is a highly sophisticated research and quality control facility that has been supplying large capacity power transformers to the worldwide market since 1910. Today, Hitachi has supplied over 6,800 units with power capacity up to 3,000 MVA and voltage up to 1,000 kV. In addition our new state of the art facility in Taichung, Taiwan opened in April, 2015. From these two factories, Hitachi can provide North American customers most of their requirements of 200MVA and larger.
