Product Description

Product Description

General Description
three-phase oil immersed distribution transformer is widely applied in 10kv, 20kv and 35kv power transmission and distribution system, worked as power and lighting for residential areas, business streets, industrial and mining enterprises. 
It adopts new insulation structure and anti-short circuit ability is increased. All the fasteners are anti-loose treated. 
It is completely sealed type. Compared with traditional oil immersed transformers, it does not have oil conservator, oil tank corrugated plate is used as cooling and heat dissipation element. The corrugated plate is elastic, it will swell and shrink according to the transformer oil volume change, so the transformer is isolated from air, oil degradation and insulation aging are prevented and slowed down.
