Totally Enclosed Oil-Immersed Transformer (S9-M)

Transformer Main functions and characters
1. Iron coil the coiled to fixed form, no cutting, no seam, big filling coefficient;
2. Annealing  treatment to core;
3. No seam on the iron  core, decrease largely magnetic resistance, no-load loss current is reduced by 60-80%;
4. Continuously coiling make use of  silicon steel, so no-load loss is reduced by 20-30%;
5. After being annealed, the core's magnetic-conduction feature could recover to its original level;
6. Wound iron core bears no seam. Owing to its compact structure, the noise goes down below 10 DB

The would  iron core  is used high  conducted silicon steel. After being coiled into sealed frame, then the core is annealed. So it has big filling coefficient.
No air seam in  magnetic path. High and low voltage windings are continuously coiled on the core, compact and tight. It is with features like low loss, low noise, high technology, energy saving and environmental protection. It could  be widely used in power distribution networks
