2mva Electric Power High Voltage Induction Melting Furnace Ehv Oil Immersed Transformer Price

This product conforms to the Chinese national standard GB1094.1-2013 <power transformer> and GB / t6451-2015 <three phase oil immersed power transformer technical parameters and requirements>. This product has adopted a series of major improves in material, technology and structure, so that the electrical performance of the product reaches the international advanced level compared to similar products. With the characteristics of high efficiency and low loss, it can save lots of power consumption and operation costs, thus has obvious energy-saving effect. It is a new product promoted by the state and one of the most popular products for users.
 

Structural features
1.Iron core
Is made of high-quality grain oriented cold-rolled silicon steel sheet, with full oblique and holeless binding structure. The iron core is of multi-stage stepped shape, with three or five joints, low loss and low noise. The rolled iron core is directly wound by special equipment, without joints and angle weight, reducing magnetic resistance and low loss. The amorphous alloy transformer core is a new kind of higher quality iron core material, with an average drop of 72% for low air loss and 50% for no-load current compared with the traditional silicon steel sheet.
2. Coil
It is made of high-quality QQ acetal enamelled round copper wire and flat copper coin drawn by oxygen-free copper rod. Coil forms include cylinder type, continuous type, new spiral type, split type, etc with sufficient electrical strength, mechanical strength and heat dissipation capacity. In order to increase the short-circuit resistance of transformer, higher quality self-adhesive transposed conductor can be used. The coil is made of self-adhesive acetal enamelled flat wire. After being wound into a coil, the enamelled flat wires are mutually bonded to form a rigid coil, which can withstand greater bending stress, thus enhancing the short-circuit resistance of the transformer. The biggest characteristic of the self-adhesive transposed conductor is that it can reduce the loss of the transformer. The multi-split conductor and transposition can greatly reduce the eddy current loss and circulation loss, reducing the temperature rise of the hot spot of the winding, and make the temperature distribution of the whole winding more evenly.
3. Oil tank
It is welded by high-quality steel plates elliptical or rectangular structures. The radiator elements are chip type radiator, expansion radiator or corrugated oil tank. The oil tank sealing is tested reliably in the factory. It is sprayed with three times of primer and one time of finish paint inside and outside. The product is salt fog proof, damp heat proof and fungus proof, which can meet the special requirements of metallurgy, petrochemical system and wet and polluted areas. It is beautiful in appearance and reliable in operation.

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!
