CCCC strings power lines in NW steep valleys and mountains



At an altitude of nearly 4,000 meters in northwest China’s Xinjiang Uygur Autonomous Region, CCCC, fearing no difficulties brought by the harsh environment and complex topography, have strung power lines in the steep valleys and mountains, to transmit power for the tunnel boring work of the Tianshan Shengli tunnel, a key part of the 1,300-km-long Urumqi-Yuli Highway project that will connect the southern and northern parts of Xinjiang. The 22-km-long tunnel will be the longest highway tunnel in the world.

There used to be a no man’s land, with no shelter, no access to water, electricity or communication network, the project manager Wu Zhengbo recalled. There was not even a makeshift road to transport materials, and they would often have to repair one by themselves; Even if it was possible to build a construction road in the steep mountains and sometimes the road would eventually become impassable due to snowfall or rainfall, they would then have to carry the materials on their shoulders or by horse. Despite these difficult conditions, they haven’t given up.

It is in such an environment that they have erected nearly 100 km of high voltage transmission lines and built the substations, among which over 300 are in mountainous areas. Thumbs-up to our brave and perseverant constructors.
