Functions of power transformer

The power transformer is one of the important equipments for the power generation, transmission, transformation, distribution systems. Its performance and quality relates directly to the reliability and operation efficiency of the power systems. The power transformer is a kind of equipment that can change AC voltage. Except transform voltage, the power transformer is also used to transform the AC current, impedance and change phase etc.. 

Types of power transformer

The power transformer mainly has distribution transformer (oil-immersed distribution transformer and dry type transformer), box-type transformer, high voltage and ultra-high voltage power transformer.

Company Introduction

Found in 1958, our factory in hydropower products has continuously been one of the national strategic turbine manufacturers in China since year 1995. It has now 246,000 square meters ground area and 68,000 square meters office building area. With over 500 workers and over 200 technicians and engineers, ADDNEW's invested factory is certificated by ISO9000-2000 and CE.

 
From the start of 2005 to the end of 2012, ADDNEW and our factory in Hunan, China have designed, manufactured and installed successfully over 170 small Hydroelectric Power Stations in Albania, Chili, Congo, India, Lithuania, Kazakhstan, Vietnam, Zambia and other overseas markets. The equipments adopted for those hydropower stations are unit-capacity from 800KW to 100MW and the total power generating capacities of each station ranging from 1600KW-200MW. All the completed stations are now maintaining their peak performance after their installations.
