S22 type double-winding non-excitation tap-changing oil immersed power transformer of 10kV

The S22 model is a product developed by our company based on the original

S13 distribution transformer. Through the research and application of new

materials and new technologies, as well as the combination of independent

innovation and technology introduction, and through the optimized and

innovative design of the iron core and coil structure,

The no-load loss has decreased by an average of 20%, and the load loss has

dropped by an average of 30%.

The noise level has decreased by an average of 20% compared to the current

national standard JB/T10088-2016.

This kind of product is applied to power system of three-phase, it is the main

transformer equipment of medium and small-sized transformer substation,

supplies power distribution, power and illumination for the industry and

agriculture.

The company introduces domestic and overseas advanced technique, adopts

the latest material and optimizes design, which enables the product structure

more reasonable, and greatly improves the product electric strength,

mechanical strength and heat-sinking capability.
