ABB again hits record levels in UHVDC technology

2016-11-28 - ABB has successfully type-tested the world's first 800 kilovolt (kV) transformer for a 10,000 megawatt (MW) ultrahigh-voltage direct current (UHVDC) transmission link in China – enough power to serve the needs of more than 20 million people.

High voltage direct current (HVDC) transmission is the technology of choice for delivering bulk quantities of electrical power over long distances. ABB has extensive experience with HVDC technology, and has developed and built converter transformers for the most demanding projects Xiangjiaba – Shanghai and Jinping-Sunan.

As demand for safe, versatile power transmission accelerates, ABB has continued to push the boundaries of UHVDC technology, which transmits even larger amounts of electricity over longer distances is an efficient and cost competitive way, but also with minimal losses and without compromising reliability.

Most recently, ABB has successfully type-tested the world's first 800 kilovolt (kV) transformer for a 10,000 megawatt (MW) ultrahigh-voltage direct current (UHVDC) transmission link in China setting a new level for the development of UHVDC technology in terms of power capacity.

This unit is a key component of the Shanghaimiao-Shandong ±800 kV UHVDC transmission link which are capable of transmitting up to 10,000 MW of power, enough to serve the needs of more than 20 million people.
