ABB Wins $63 Million Order for Ultrahigh-Voltage Transformers

02/24/2011 10:00AMSign-up to receive press releases.

ABB has won an order worth $63 million from China Southern Power Grid Co. Ltd to design, supply, install, and commission 800 kilovolt (kV) ultrahigh-voltage direct current (UHVDC) transformers for a converter station that will form part of the Nuozhadu-Guangdong transmission system. China Southern Power Grid is a state-owned utility and is responsible for building and operating the power grid in the southern part of the country.

"We are pleased to continue supporting China’s efforts in further developing its power transmission and distribution network,” said Bernhard Jucker, head of ABB’s Power Products division. “These transformers are designed for high reliability, efficiency, and optimized life cycle costs.”

The 800 kV UHVDC transformer is a key component of ultrahigh-voltage power links that deliver large amounts of electricity over very long distances. There are many challenges involved in building such transformers, including increasing the technical specifications of the transformer’s insulation and redesigning critical components like bushings.

UHVDC technology enables more efficient use of renewable energy sources, reduces dependency on fossil fuels, and helps cut carbon dioxide emissions. It is particularly suitable for large countries like China, where the centers of power consumption are often far from power sources.
