Oil-immersed Enclosed Transformer
)
)
This three-phase oil-immersed power transformer uses cold-rolled silicon steel sheets such as 27QG120, 27QG100 and 23RK085 as core material. In actual production, the performance indicators of the adopted core are no less than drawing requirements.
The product adopts a fully-enclosed corrugated steel tank structure, which isolates transformer oil from ambient air. It prevents the reduction of dielectric strength caused by transformer oil absorbing moisture from air. Besides, it stops oxygen entering the tank to avoid aging of insulating materials, thus extending product service life and improving social benefits.
