Outdoor type 6.6kv 7.2kv 10kv 11kv 33kv oil immersed distribution power Transformer suppliers in China

S13/10KV three Phase Oil-immersed Transformer
Product introduction

The S13 series 10kv oil-immersed transformer designed and produced by our company adopts the structure of fully sealed corrugated oil tank, which is free of maintenance, convenient for maintenance and stable for operation, with remarkable economic benefits.Long service life, maintenance-free operation.The fully sealed transformer box cover and the box edge adopt bolt connection or welded structure to isolate the contact between oil and air, the insulation will not be affected by moisture, greatly reduce the aging rate of insulation, and improve the service life.Compact design structure, low running noise.Because of the use of new materials and new technology, noise reduction, no oil storage tank, the height is lower than similar products.No need to change oil in the normal life period, improve the safety and reliability in operation.
 

Product advantages

1. 1. The core:
   All adopt high quality grain oriented cold rolled silicon steel sheet, all inclined without hole binding structure, the iron core is multi-step ladder, three or five joints, low void loss, low noise;The coiling iron core is directly wound by special equipment, without joint and Angle weight, which reduces the magnetoresistance and reduces the air loss.
   2. The coil:
   It is made of flat copper coin or copper knot made of high quality non-oxygen copper rod, which has the form of circular simple type, continuous type, new spiral type, split type, etc. It has sufficient electrical strength, mechanical strength and heat dissipation ability.
   3. The tank:
   Is made of high qualified steel plate welding and become, such as elliptic shape, structure, heat dissipation component adopts chip radiator, expand the radiator or corrugated tank, fuel tank and reliable sealing experiment was carried out in the factory, both inside and outside surface after pickling, phosphating treatment, both inside and outside surface of three times primer, paint spraying again, product has, hot and humid, salt mist prevent mould, beautiful durable, enhance the operation reliability.Adopt corrugated board oil tank, the change of oil volume caused by temperature by the elastic adjustment of corrugated sheet so that the transformer oil and air isolation extended use orders.
   4. Energy saving
   Due to the special structure of the core and the annealing process of rolling high quality cold rolled silicon steel sheet with crystal orientation, the no-load loss, no-load current and noise of this series of transformers are reduced by 30%, 70% and 8 db respectively compared with the same capacity S9.

Company Introduction 

Qingdao Hengfengyou Electrical Engineering Co., Ltd. (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!
