It is cascade structure, which the primary winding has four frade grade windings surrounded on the limbs of two single phase two-limb core. The insulation consists of high voltage cable paper, phone paper and cardboard etc., which will be immersed with transformer oil after desiccating under vacuum. It has advantages of stable and reliable performance of insulation, rich successful experience, a long life time and convenient maintenance.
Perfect fluidity performance of transformer oil is good for heat dissipation. It also has self recover ability for the failure of partial discharge caused by air bubble and dust.
It has three secondary windings, which has individual measuring and protection winding.
There is a multi function oil drain valve on the base, which make it convenient for sampling, draining and refilling.
The secondary terminal board is made of epoxy casting, the seal performance is more reliable.
