Features

The fully sealed transformer adopts a fully oil-filled sealed type. The shell of the corrugated oil tank adapts to the expansion of the oil with its own elasticity and it is a sealed oil tank, which has been widely used in various power distribution equipment

+The iron core is made of high-quality cold-rolled oriented silicon steel sheet, which is manufactured by the automatic cross-cutting process and the the step lap process, which improves the distribution of magnetic flux density inside the iron core, reduces the vibration energy of the iron core, and effectively reduces the noise and loss;

+The coil is winded with high-strength enameled wire (or paper-covered wire), cylindrical (or cake)structure with uniform ampere-turn distribution, reasonable insulation structure, and strong short-circuit resistance;

+The transformer body is fastened with an anti-loosening structure, the fastening part is equipped with locknut, and the non hanging core structure is adopted to ensure that it will not come loose after long-distance transportation;

+The corrugated sheet of the corrugated oil tank replaces the oil conservator. The corrugated sheet can expand and shrink with the change of the transformer oil volume, isolate the transformer from the atmosphere, prevent and slow down the deterioration of the oil and insulation being affected with damp, enhance the reliability of operation, and keep the transformer operate normally without maintenance;

+Equipped with “remote monitoring”signal thermometer and pressure release valve, which enhances the reliability of transformer operation.
