1. Energy conserving

Compared with the original S9 type, no-load loss of S11 decreases by 10.25% averagely, no-load current decreases by 37.9%, and the running expense decreases by 18.9% averagely.

2. High reliability

Structurally improve the effective supporting of both HV and LV coil end faces, adopt the new body location structure. Expand the application scope of the cylindrical coil, and adopt a series of new material, new subassembly, new fastening pieces and new process to make both the performance of the product and structure reach up to higher level, improve the running reliability of the product.

3. The service life is prolonged

Compact structure, small volume, low noise, high efficiency and steady performance of S11 series of transformers prolong the service life of transformers.

S11 series of oil-immersed transformers produced by our company are low loss series of products that have international advanced level. The energy conserving effect is significant. They can be widely used in urban and countryside industrial and agricultural power grid. The iron core adopts the new process of the stepping lamination, resulting in improvement in no-load performance and reduction in noise.
