Vertical bell housing hand-wheel manual cage tap changer central voltage regulation

The products in this series are de-energized tap-changers designed specifically for oil-immersed de-energized voltage regulating transformers. They adopt a vertical cage structure and are installed in a bell type configuration. These tap-changers have wide-ranging applications in power, rectifier, and electric furnace transformers with rated frequencies of 50Hz and 60Hz, rated voltages of 35kV, 66kV, and 110kV, and rated currents ranging from 125A to 2000A. It is crucial to operate these tap-changers only when the transformer is de-energized.
