Vertical tank-top hand-wheel manual cage tap changer neutral point voltage regulation

This series of products features de-energized tap-changers designed for oil-immersed de-energized voltage regulating transformers. They utilize a vertical cage structure and are installed in a bell type configuration. These tap-changers can be extensively used 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 essential to ensure that the transformer is de-energized before operating these tap-changers.
