Product Description

10kv series Oil-immersed transformer 

Primary Votage        6KV 10Kv 11Kv
Secondary voltage  0.4KV
Ccapacity: 30KVA -31500KVA



S11 full-sealed oil-immersed power transformer developed by the company has the advantages of low loss,low noise and high efficiency and can achieve good energy-saving effect and reduce pollution.

 Compared with common oil-immersed transformer ,it is unnecessary for full-sealed transformer to be equipped with oil conservator and change in oil volume is automatically adjusted and compensated by elasticity of corrugated sheet of corrugated tank , and transformer is isolated from air to prevent and slow down oil degrading and insulation aging, enhance operational reliability, with normal operation and no maintenance.   

Product features

1. Product maintenance is simple.
2. The low voltage is wound by copper foil, so that the electric field of the transformer is evenly distributed. The low-voltage inner frame is formed by forming a hard paper tube, and the high-voltage outer half-layer is layered with a layer of glass adhesive tape. The compacting block is laminated wood. The mechanical strength of the transformer and the vacuum oil injection of the transformer can completely eliminate the air bubbles in the coil, thereby improving the overall resistance of the transformer to sudden short circuit.

3. The box is made of stainless steel bolts for a beautiful appearance.
4. The fuel tank adopts a fully sealed oil tank to isolate the transformer oil from the air, slow down the aging of the transformer oil, and the molded parts are molded parts to enhance the reliability of the transformer seal.

Application 

This product is widely used in urban and rural power grid construction and renovation projects. This product is especially suitable for areas where there is insufficient power and load fluctuations and where daily maintenance is difficult. Because the transformer adopts a fully sealed structure to prevent the transformer oil from coming into contact with the air, it can operate in a humid environment and is an ideal power distribution equipment in urban and rural distribution networks

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!
