66kV Power Transformers
66 KV Power Transformers
Overview
66kV Power Transformer is a critical component in medium to high-voltage electrical power transmission and distribution systems. Its primary function is to step up or step down voltage levels efficiently while ensuring minimal power losses during the transmission process. These transformers are widely used in substations, grid interconnection points, and industrial facilities where power needs to be transferred across long distances or distributed at lower voltages.
