Product Overview

>66kv Power Main transformer is main primary equipment in power grid, especially on long distance transf-ormation.

>General type is used for up and down voltage ,auto transformer is used for coupling power system with different voltage level.

>There are various types power transformer such as double winding, triple winding, off circuit tap change, on load tap change, high impedance.

>Apply to grid power station, hydropower station, thermal power plant, industrial power station and soon.

>HENGFENGYOU ELECTRIC using high purity copper winding, Bao-steel high performance CRGO four stages lamination, loss level could better than GB and IEC standard.

>Using processes like tension plate, cushion block precompression, outside and inside gagger to guarantee performance of loss level, dynamic stability, heat stability, and noise level.

>Nice appearance with bending corrugated bell jar type oil box.
