General
This Outdoor oil immersed type power transformer use for medium voltage to medium voltage power system.
It have been used in substation.
The transformer high quality transformer oil, high quality CRGO core, primary and secondary use pure electrolytic copper, both winding and core have shielding processing.
It can use Germany MR break, to be on load tap changer, or to make non load tap changer.
