Description

3-phase Oil Immersed Distribution Transformer

Features:

1. The iron core is made of silicon steel sheets and strips, which is close to circular cross section without joints and non-grading. The iron yoke and iron core column are connected with rounded corners, and the iron core is closed.

2. The high and low voltage coils are directly wound on the iron core, and the two coils have good concentricity and strong short-circuit resistance.

3. Eliminate the oil conservator and adopt a corrugated oil tank. The change in oil volume caused by temperature is adjusted by the elastic adjustment of the corrugated sheet, which isolates the transformer oil from the air and prolongs its service life.

4. The corrugated fuel tank has low temperature rise, small floor space and beautiful appearance.

5. The core processing is fully mechanized, which reduces labor intensity, improves product quality and stabilizes quality.
