China Air Core Reactor Manufacturers, Converter Reactor Suppliers, Test Reactor Factory

World First ±1100kV Dry-type Air-core Smoothing Reactor

TEEE was the first company in the world to successfully design and develop±1100kV dry-type air-core smoothing reactors, which were specially manufactured and delivered to SGCC in 2018 for the Changji-Guquan UHV DC transmission project. The project has achieved the world's highest voltage level of ±1100kV and has been running perfectly for the past 5 years.

World First 500kV HV Dry-type Air-core Shunt Reactor

Pioneer in the development of 500kV high voltage dry-type air-core shunt reactors in the world and these reactors have been delivered in bulk to the Sylvania Project of the Brazil Holding Company of SGCC in 2023, providing key support for the third stage expansion of UHV transmission lines in Brazil.
