2.Product introduction

The On-Load Tap Changer (OLTC) is a critical electromechanical device used in power transformers to regulate output voltage without interrupting the load current. By switching the tap connections on the transformer winding, the OLTC dynamically adjusts the effective number of turns, ensuring stable voltage levels even under fluctuating load conditions.
