ABB to supply ultrahigh-voltage transformers to China

ABB為中國提供特高壓變壓器

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從中國南方電網公司贏得一份價值6300萬美元的訂單，為糯扎渡——廣東輸電工程組成部分的一座換流站設計、制造、安裝并調試800千伏特高壓直流變壓器。

"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電力產品業務部負責人Bernhard Jucker表示：“我們為可以繼續支持中國進一步發展輸配電網絡而感到高興。這些變壓器在設計上具有高可靠性、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.

中國南方電網是中國兩大國有電網公司之一，負責中國南部電網的建設和運營工作。

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.

800千伏特高壓直流變壓器是實現遠距離、大容量輸電的特高壓輸電線路的關鍵設備。建造這樣的特高壓直流變壓器需要克服許多挑戰，例如需要提升變壓器的絕緣性能、對絕緣套管等關鍵設備進行重新設計等。

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.

特高壓直流輸電技術可以幫助更加高效地利用可再生能源、降低對化石能源的依賴，同時降低二氧化碳排放。特高壓直流技術在像中國這樣國土遼闊的國家尤其適用，因為這些國家的電力使用中心通常都遠離能源來源地區。

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.

特高壓直流技術是ABB集團50多年前率先研發的高壓直流輸電技術的進一步發展，也是近20多年來輸電線路在輸電容量和效率上實現的最大技術突破。
