Beijing, Feb 28 (IANS) A 660-kilovolt direct current
power transmission system, said to be the world's
first, began to supply energy Monday to a province
that is located over 1,300 km away.
The transmission system began carrying power from
northwest China's Ningxia Hui Autonomous Region to
the eastern Shandong Province.
The 10.4-billion-yuan ($1.58 billion) project is
part of China's west-east power transmission programme,
The cable system has a current-carrying capacity
of 4 million kilowatts of electricity over a distance
of 1,333 km through five provinces and regions.
China's coal resources are mainly based in the west
and the north. The west-east power transmission programme
was initiated in 2000.
Cui Jifeng, general manager of Ningxia Power Co.
which is a subsidiary of the China Power Grid Co.,
said the system was built to supply hydropower generated
on the upper reaches of the Yellow River as well
as thermal power produced in Ningxia to coastal Shandong.
The system was designed, produced, constructed and
tested by Chinese companies, he said.
