The Challenge
Sinohydro, a Chinese state-owned hydropower engineering and construction company, wanted to install fiber optic cables through a vertical shaft 500 meters deep. They needed conduit pipes that would withstand the tensile forces of the pipe weight. The pipes have to be embedded in concrete, so they have to resist the temperature of the concrete during casting.
Pexgol Solution
Pexgol was chosen due to their ability to withstand high tensile forces and high temperatures.The 63 mm pipe was provided in 13 coils of 700 m each and the 50 mm pipe was provided in 13 coils of 1080 m each.
Only a double mechanical connector was used to hold the pipes above the pit.
