Dry-type transformer has the advantages of large short-circuit resistance, little maintenance work, high operation efficiency, small dimension and low noise, which is commonly used in places with high requirements of fireproof and explosion-proof. This type transformer is widely used in local lighting, high buildings, airports, docks, CNC machinery and others. Its cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). The transformer can operate continuously for a long time under rated capacity under natural air cooling. Output capacity of the transformer can increase by 50% under forced air cooling. It is suitable for intermittent overload operation or emergency overload operation. Due to the load loss and impedance voltage increase significantly when overload, it is not suitable for long time continuous overload operation.
Product featuresConditions of use
1. Low energy consumption: The adoption of isotropic soft magnetic material generates low magnetization power, high electrical resistivity and low eddy current consumption. The no-load loss and current of the core made of amorphous alloy are very low, only 1 / 3 of that of silicon steel sheet.
2. Strong corrosion resistance: the amorphous alloy core is fully wrapped by resin and high temperature resistant silica glen which effectively prevent corrosion and falling off amorphous alloy fragments, and provide better protection for the core and coil.
3. Low noise. Improvement of the structure of iron core and coil and adoption of special noise -reduction materials greatly reducing the operation noise.
4. Strong short-circuit resistance. This product adopts three-phase five-column structure, and the iron core is protected by frame structure. Featured by low temperature-rise and strong heat dissipation, this product can work by 150% rated load under air cooling condition. Perfect temperature control protection system is applied to provide reliable guarantee for safe operation of transformer
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 for Distribution Voltage Electric Transformer:
1.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. .
2.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!
