Product Description

Power transformer is widely used as the basic power product. In the past decades, China and all over the world have been using plug - in power transformer for a long time, whose features are not improved fundamentality. The S13-M-RL、S11-M-RL series solid triangle iron core power transformers developed by our company are another revolutionary transformer after plug-in and winding iron core transformers. It is a kind of transformer that has more reasonable structure, better performance and more energy saving.

With the construction and transformation of urban and rural power grids and launching of various power projects, how to improve the technical content of power transformers, better implement the national policies on energy conservation and environmental protection, and actively promote new products of energy conservation, low consumption and environmental protection has become an important issue for us. The solid triangle iron core power transformer developed by our company is a kind of transformer that uses traditional materials but with low operation noise, low loss and excellent material saving features. Fully in line with international and domestic low-carbon economy and energy conservation and emission reduction guidelines and policies. The product has been incorporated into the first batch of energy-saving products selected by national energy efficiency power plant; Budget investment projects on resource conservation and environmental protection of the Party Central Committee; The state economic and trade commission and the former state grid corporation of China have published articles promoting this energy-saving product; Shenyang Substation also promotes the triangle iron core transformer as replacement products of plug and flat winding core power transformer.

Distinctive “Core”

Triangle iron core does not need to be cut or punched, eliminates the transverse and longitudinal joints of traditional transformers, reducing magnetic resistance; cross section of iron core is round, thus the filling coefficient of the iron core is biggest, triangle solid structure makes its three-phase magnetic circuit equal and shortest, realizes the iron core structure of ideal transformer for people.

Triangle iron core is made of continuous steel belts from narrow to wide and then wide to narrow. Wind the three inner cores whose cross section are semicircle, and then piece the three inner cores solidly, form the three iron cores whose cross section to be nearly circular. The three-phase magnetic loop is perfectly symmetrical and equal, reduce the iron yoke, high core filling coefficient, its structure is an ideal transformer structure that is widely recognized. It is incomparable by flat winding core. Each testing data of triangle solid winding core power transformer is better than flat winding core power transformer. Triangle solid winding core is a great breakthrough and leap in iron core of power transformer. Its birth was hailed as "a revolution in the iron core of power transformers". Thus, triangle solid winding core power transformer is recognized energy saving, environmental protection, ultra-quiet green power transformer.

Performance Advantage

Solid winding iron core transformer breaks the traditional planar structure, adopts solid triangle structure, making more reasonable combination of the iron cores by piecing three completely same single frames. The three phase magnetic circuits are perfect symmetry and same in length, ensure three phase power supply balance, decrease the magnetic resistance greatly, and reduce field current, no-load loss significantly. Thus the mechanical strength is higher, structure is more stable.
