The electricity supply to the Qinghai-Tibet railway in construction is safe and reliable, vowed an official from major solar electric power generation facilities and an extra-high voltage transmission line supplier.
Based in Changji of Northwest China's Xinjiang Uygur Autonomous Region, the Tebian Electric Apparatus Stock Co Ltd (TBEA) provided half of the solar electric power generation facilities and extra-high voltage transmission line from Qinghai to Gansu for the railway line on the plateau.
"With 25 patents in the fields, the technology of my company is reliable," said Zhang Xin, chairman of the TBEA board committee and vice-chairman of China National Machinery Industry Federation.
TBEA was China's largest transformer, wire and cable research, manufacture and export company, as well as the largest key component assembling base for solar energy products in the country.
The Qinghai-Tibet railway is the highest-altitude railway in the world. Most of the railway lines are built in areas of 4,500 metres above sea level, and the highest point in the project was 5,072 metres in elevation.
Extreme cold, lack of oxygen, low pressure, and massive sandstorms and thunderstorms in the region challenged the functioning of electric facilities for the railway line.
The extra-high voltage transmission line from Qinghai to Gansu, spanning 260 kilometres, is the world's first plateau extra-high voltage line, according to Zhang.
"The project was completed by the end of July," he said.
The line facilities, invented specially for the plateau railway, enhanced the function while reduced the weight, according to the board chairman. The facilities are also environmentally friendly.
"The line reduced electromagnetic pollution," he said.
The extra-high voltage transmission line will begin to work next month for the Qinghai-Gansu section of the Qinghai-Tibet railway.
Meanwhile, half of the solar electric power generation facilities on the Qinghai-Tibet railway are provided by TBEA. The other half of the facilities is imported.
"Solar electric power generation is needed on a railway line on plateau," he said.
TBEA also provided some of the photoelectric circuit and solar electric power generation facilities for Olympic venues.
