BEIJING, May 15 -- Chinese political advisors on Thursday discussed ways to extend the country's ultra-high voltage (UHV) system to boost its electricity transmission capacity from energy-rich regions to areas that are short of power.

Speaking at a symposium held by the National Committee of the Chinese People's Political Consultative Conference (CPPCC), attendees suggested ways to improve UHV power transmission technologies and speed up the building of electricity grids across the country.

The symposium, presided over by Yu Zhengsheng, chairman of the CPPCC National Committee, is a regular event for members from various fields and backgrounds -- mainly those from non-Communist parties or with no political party affiliation -- to discuss and propose ideas.

With the consensus that the UHV power transmission network is vital to national energy security and environmental protection, attendees called for efforts to extend the UHV system to boost electricity transmission capacity.
