China Rockwill F series on load tap changer (OLTC), which has advanced structure, long service life and high reliability. It is normally used in oil-immersed three-phase transformer as three phase step voltage regulator with frequency 50Hz/60Hz, voltage up to 40.5KV and rated current up to 400A. The on load tap changer is to regulate the output voltage of a transformer. It does this by altering the number of turns in one winding and thereby changing the turns ratio of the transformer. Contact us for more details and low price quotation.
