ABB to supply ultrahigh-voltage transformers to China

ABB为中国提供特高压变压器

February 17, 2011 - ABB won an order worth $63 million from China Southern Power Grid 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.

2月17日消息——ABB从中国南方电网公司赢得一份价值6300万美元的订单，为糯扎渡——广东输电工程组成部分的一座换流站设计、制造、安装并调试800千伏特高压直流变压器。

"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.”

ABB电力产品业务部负责人Bernhard Jucker表示：“我们为可以继续支持中国进一步发展输配电网络而感到高兴。这些变压器在设计上具有高可靠性、高效，而且生命周期成本低。”

China Southern Power Grid is one of two leading state-owned utilities in China responsible for building and operating the power grid in the southern part of the country.

中国南方电网是中国两大国有电网公司之一，负责中国南部电网的建设和运营工作。

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 – for instance, increasing the technical specifications of the transformer’s insulation, and redesigning critical components like bushings.

800千伏特高压直流变压器是实现远距离、大容量输电的特高压输电线路的关键设备。建造这样的特高压直流变压器需要克服许多挑战，例如需要提升变压器的绝缘性能、对绝缘套管等关键设备进行重新设计等。

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.

特高压直流输电技术可以帮助更加高效地利用可再生能源、降低对化石能源的依赖，同时降低二氧化碳排放。特高压直流技术在像中国这样国土辽阔的国家尤其适用，因为这些国家的电力使用中心通常都远离能源来源地区。

UHVDC is a technological development of HVDC, pioneered by ABB more than 50 years ago, and is the biggest leap in transmission capacity and efficiency in more than two decades.

特高压直流技术是ABB集团50多年前率先研发的高压直流输电技术的进一步发展，也是近20多年来输电线路在输电容量和效率上实现的最大技术突破。
