The wires are steeped in a metallic liquid at 450 °C.
In the cable strand production workshop, there are 127 distribution frames. Each steel wire will follow a unique route to the assembly area. After that all 127 strands will eventually meet at the convergence frame, and be bundled to make a hexagonal cable.
Every one of the 172 hexagonal strands is formed of 127 wires.
Each steel wire will have its unique position on the bridge. Every one of the 172 hexagonal strands is formed of 127 wires. This is how the key cables are made so that each of them is capable of bearing a 90,000-ton load. After six hours of work, a 2,600-meter-long cable strand has been completed.
Each steel wire has its unique route.
This meticulous work, all made in China, ensures that a state-of-the-art infrastructure will be made successfully and of the best quality.
