UHV key to Brazil's power problems

State Grid Corp of China's ultra-high-voltage technologies have become key to the expansion of the company's presence in Brazil, according to an energy expert.

"UHV, which transmits a large capacity of electricity over long distances with low losses, is exactly what Brazil needs for its power grid construction due to the nation's territorial characteristics," said Han Xiaoping, an analyst at Beijing-based cnenergy.org.

SGCC plans to purchase the shares in Brazilian electricity transmission company CPFL, which are currently held by Camargo Correa SA, according to an announcement made by CPFL.
