Oil Immersed Transformer

Excellent economic performance:

No-load current reduces by an average of 60%~80%,

No-load loss cuts down by an average of 25%~35%.

Long service life:

Thetransformer tank adopts fully sealed structure; the tank and tank flange can be connected by bolts or welding. Transformer oil is isolated from air to extend service life.

High operational reliability:

Components related to tank sealing are optimized to improve reliability, and advanced manufacturing processes are applied to guarantee stable sealing performance.

Small floor space:

Corrugated sheet radiator is adopted for transformer tank. Thermal expansion and contraction of corrugated plates with oil temperature variation replaces the function of conservator. The corrugated tank features elegant appearance and small floor occupation.
