ABB transformers to support China’s highest voltage wind farm substation

2010-08-19 - State-of-the-art power transformers to support integration of wind power and provide clean electricity to millions in north-east China

Zurich, Switzerland, Aug.19, 2010 – ABB, the leading power and automation technology group will design, supply and install all six main transformers for the 500 kilovolt (kV) Tongyu substation under construction in the Jilin province of north-eastern China.

Tongyu will be the highest voltage substation in the country for the transfer of wind power. It is designed to integrate 2300 megawatts of electricity into the grid and plays an important part in the province’s wind power development plan.

“Renewable energy, especially wind power, is an important element of China’s focus on clean energy development,” said Tarak Mehta, global head of ABB’s Transformers business, part of the company’s Power Products division. ”The transformers used in this project will play a key role in integrating wind energy into the grid and ensure the efficient transmission of electricity to millions.”

The transformers are based on ABB’s patented TrafoStar technology and designed to minimize power loss and maintenance needs. Their ability to withstand short circuits will be integral to the reliable and safe operation of the substation, mitigating the occurrence of power outages. They will be supplied from ABB’s state-of-the-art transformer manufacturing unit in Chongqing, one of the largest of its kind in the world.

Transformers are integral components of any electrical grid and are critical elements in the efficient and safe conversion of energy across diverse voltage systems. ABB’s transformer portfolio includes power transformers, rated up to 1,000 kV, dry- and liquid-distribution transformers, as well as related services and components.

ABB ( is a leader in power and automation technologies that enable utility and industry customers to improve their performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 117,000 people.
