20KV and 10KV Convertable Epoxy Resin Cast Transformer SC(B)10-30~2500/20(10)

Author:ZTELEC   Update time:2018-04-17 13:43:50


When the grid voltage is 20kv or 10kv, the transformer in this series can control the connection status between two windings on high voltage coil in each phase via conversion device, and realize voltage conversion through series or parallel connection without changing the output voltage, thus enabling one transformer to connect with two electrical voltage systems like 10kv or 20kv asynchronously, where the transformer acts as a transition of upgrading the grid voltage from 10kv to 20kv. In this way, it can achieve repeated investment reduction, efficient conversion, and stable performance.
