Product Description

Non-Encapsulated Power Dry Type Transformer 400kVA Rated Frequency 50Hz


·Product introduction
SCB10 / 11 series non-encapsulated dry-type transformer has got the advantages of safety, reliability, energy-saving, fireproof, explosion-proof and easy maintenance, and it has advanced design, reasonable structure and beautiful appearance. This type transformer is most suitable for harsh places with high fireproof requirements, big load fluctuation and dirty and humid environment, such as high buildings, airports, subways, power plants, metallurgy, hospitals, shopping centers, residential complex, petrochemical, nuclear power, nuclear submarines and other important places.

 

·Structural features
1. unique ceramic insulation structure: adoption of insulating cylinder and high frequency ceramic cushion block generates no deformation.
2. VPI process: Nomex insulation material is first applied to high and low voltage coils, and then immersed repeatedly in H-class insulation liquid with special formula in vacuum pressure equipment. After several baking, coils are sealed externally by high-strength insulation material and then solidified at high-temperature. The high voltage coil adopts a continuous structure with high mechanical strength and good heat dissipation.
3. The iron core is made of silicon steel sheet with high conductivity and magnetic properties. A stepping 45 °fully-oblique structure is adopted. The winding and iron core are fixed by elastic device, thus low no-load loss and noise. Surface of iron core is treated by special process. The iron core is moderately clamped by the pull screw, and the up and low clamps are connected by pulling board and fixed with the base and the winding. The winding is fixed by elastic cushion block. This buffer structure can reduce the vibration and noise of the winding.

4. The outgoing line terminal is fixed on the upper part of the winding. The tap changer is in the middle, and the low-voltage line terminal is a plate-type conductive bar, which is faxed by cold pressed welding.


Serve condition:

1. The maximum ambient air temperature shall not exceed 40 ºC, and the minimum not lower than - 25 ºC;
2. The altitude shall not exceed 1000m. If special customized transformers and low-voltage components are applied, the altitude can reach 4000m;
3. The vertical inclination shall not be higher than 5 °, and no violent vibration and impact;
4. The air humidity shall not be more than 90% (+ 25 ºC);
5. working in places where there is no gas and conductive dust that will seriously affect the insulation of transformer, no explosion hazard and no corrosion of electrical components;
6. Outdoor wind speed shall not exceed 35m / s.
7. If beyond the above normal use environment conditions, specially customized product is available with our company through mutual communication.

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!
