Company information
We, Chuo Electric Industry Co., Ltd., are engaged in the development of transformers in fields such as elevators, industrial and communication equipment, and power distribution. Among these, we are particularly focused on special transformers and reactors that require high functionality, high precision, and high added value. These are used in the core components of cutting-edge electronics products, including elevators, management systems, inverter control systems, and emergency power supplies. Consequently, the demands for our products are stringent, and it goes without saying that high technology is required, especially as we increasingly engage in joint development with major companies. Notable achievements include the elevators in the Tokyo Metropolitan Government Building and the Yokohama Landmark Tower. Since our founding, we have been dedicated to transformers, and as a development-oriented company that also looks at related peripheral equipment under the theme of power supply, we will continue to challenge ourselves to create high added value products in collaboration with our customers.
