Advantage of structure
l We employ spiral coil with longitudinal oil path to make a better interior cooling effect;
l We improve the effective support of the coil’s terminal surface to strengthen the anti-short circuit current capability.
l We employ new hoisting structure and body-positioning frames to guarantee that the long distance transport and movement will be more reliable;
l Canceled the oil tank, the wave wings of tank instead of the tubing as a cooling device, corrugated tank is made of high quality cold press sheet on dedicated machine and enhance the reliability of running.

Improved from S9 series product, S11 series product reduces the no-load loss by 30%, no-load electric current by 70~85%, average temperature by 10K, noise level by2~4db, and double the products service life. Even under 20% overloads, it can also work for long period of time.

l Energy conservation. Compared with the original S11, the average no-load loss reduced by 20% or more, the no-load current is reduced by 25% or more, operating costs dropped by an average of more than 15%.
l Long service life, transformer core with new core material, and greatly reduce the loss significantly extending the life of the transformer.
l Small footprint, the core is made from high quality cold rolled grain oriented silicon steel sheet; high, low voltage winding made of high quality oxygen-free copper wire and multilayer tact process structure; All fasteners are used special relax treatment, the high mechanical strength, and transformer sizes small, light weight, and the fully sealed tank, can be widely used in various environments.
