Product Description

6kv/11kv/22kv/33kv 300kva Three Phase Oil Immersed Power Electrical Distribution Transformer 

The three-phase oil-immersed transformer applies new type insulation structure and improves the ability of short-circuit resistance.The iron core is made of high-quality cold-rolled silicon-steel plate.High-voltage winding group is made of high quality copper wires and it adopts multilayer cylindrical structure.All fasteners have been processed with special treatment to prevent them from loosening. 

The product have many advantages such as high efficiency,high-tech,low loss.Its social benefits are remarkable that it will save much of electricity consumption and operating cost.

6kv/11kv/22kv/33kv 300kVA Three Phase Oil Immersed Power Electrical Distribution Transformer
 

 

1. Core
New high-quality silicon steel sheet is adopted, mainly 0.35 thick h18, h14, H12 and Z11 high-quality silicon steel sheet. We select the most suitable material according to the requirements and use conditions of customers to achieve the best design and performance of Hengfengyou transformer.
2. Coil
Pew, UEW, EIW, seiw, FEAI enamelled wire and glass-fibre covered wire are used for coil. The temperature resistance grade is f (155 ºC), H (180 ºC), HC (200 ºC), C (220 ºC). (the conventional temperature resistance grade is 180 ºC of H grade).
3. Insulating materials
High temperature resistant insulating paper is used as insulating material, which has multiple properties of high temperature insulation, flame retardant and moisture resistance.
4.connecting terminal
For small power, we use terminal strip which is beautiful in appearance and shows excellent pressure resistance, temperature resistance, flame retardant performance. For high power, we use high quality copper busbar.
5. The oil tank is corrugated oil tank, with three times of primer and one time of finishing paint spraying for inside and outside surface. The product is salt fog proof, damp heat proof and fungus-proof, beautiful, durable and reliable.

Company Introduction 
6kv/11kv/22kv/33kv 300kVA Three Phase Oil Immersed Power Electrical Distribution 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.
3.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!
