A low magnetic steel plate is applied as the traction plate, which is closely connected with the upper and lower clamping clamps to form a steel frame structure. The structure produces smaller load loss and lower noise.Product advantages:Low loss and noise: the iron core plate is made of high-performance silicon steel sheet in form of five-layer stepped fully-oblique joints, which reduces no-load loss and noise. The oil tank manufacture adopts magnetic shielding technology and copper shielding technique. Measures are taken for the core structure parts to reduce eddy current loss according to positions of leakage magnetic field, which reduces load loss and fundamentally solves local overheating of transformer.Safeoperation: the partial discharge capacity is kept below 100pc. The cooling structure is designed reasonably in order to prolong the service life of transformer and improve its short-circuit resistance. In this way, when the transformer is short circuited, the mechanical stress of the winding conductor is low, combined with other short-circuit withstand measures and strict production process, to guarantee safety.Reliable operation: Atpresent, oil immersed power transformer usually controls the operation of an on-load transformer by limiting the average temperature-rise of windings to prolonged the thermal life of transformer. During development stage, controls of hot spot temperature is more important than that of average temperature-rise for large capacity UHV transformer. For transformers with natural oil circulation, the average temperature-rise of oil may meet the requirements, while the temperature-rise of hot spot may exceed the limit. Therefore, it is necessary to calculate and strictly control the hot spot temperature rise of large capacity transformer.Easy installation and maintenance: In order to reduce the workof field installation, all accessories are pre-installed before leaving the factory. The secondary cable is laid on the main body of the transformer in the factory and led to the terminal box and control box. Most large capacity transformers adopt natural oil circulation and air cooling, and maintain 70% cooling capacity when the fan stopped.Transformer StructureNote:Due to continuous product improvement, the dimensions provided in this sample are for reference only.

(hereinafter referred to as Hengfengyou) is a large-scale enterprise group with electricity transmission and distribution as its main business,which integrates scientific research, development, manufacturing and trade. After 30 years rapid economy development in China, Hengfengyou now is a leading R & D, manufacturing and service base for MV , HV and ultra-HV power distribution equipment in China. At present,we have 50 senior technicians and more than 300 employees, with a complete sales and service system. Our products sell well at home and abroad, and our annual output value adds up to $100 million. . At present, Hengfengyou has 6 wholly-owned and holding subsidiaries, which are respectively engaged in R & D, manufacturing and service of transformers, switchgear, package/unit substation, pole-mounted high-voltage vacuum circuit breakers, new energy, and electrical engineering. For a long time, the company has maintained close technical exchanges and cooperation with domestic and foreign universities, scientific research institutes and electric power enterprises. Hengfengyou independently designed and developed SCB series dry-type transformer and SC series oil immersed transformer. Our product performs with high operation efficiency, and obvious energy conservation. The overall performance index reaches the world's advanced level. The company also maintains long-term strategic partnership with Schneider, ABB, Simens, Chint and other electric suppliers. We absorbed foreign advanced experience in electrical equipment production and independently designed and developed a series of substation equipment, which realized the automation and intelligence of the substation, and of which the performance has been highly recognized by the user at home and abroad. In the following five years, the company plans to build an intelligent workshop with an annual output of 100000 transformers.Then,the intelligent robot will replace 80% of the existing labor force, which will greatly improve the production efficiency, lower production cost, and produce more energy-saving, environmentally friendly, more safe and reliable the product for the users!
