Rotary Tap Changer – Precision Voltage Regulation for Distribution Transformers
Our Rotary Tap Changer is a high-precision switching device designed for use in oil-immersed distribution transformers, enabling manual or automatic adjustment of the transformer winding tap position to regulate output voltage. It allows operators to maintain stable voltage levels in response to load fluctuations, improving the efficiency, reliability, and performance of power distribution systems.
These rotary tap changers are engineered with robust mechanical structures, featuring high-conductivity copper contacts, arc-resistant insulating materials, and smooth rotary switching mechanisms. They support multiple tap positions and can be customised to suit varying transformer capacities and specifications.
