Significant Progress on Jinhua-Taizhou Railway

Post Time: 2020-01-08

In the early morning of January 1, 2020, the good news came that the first contact catenary cable of Jinhua-Taizhou Railway was erected in the village of  Zhuangtou, Lengshui Town, Pan'an County.

Catenary is a collective name for the live wires on the railway line. Electric trains rely on the pantographs on the top to contact the catenary to obtain power and run at a high speed, along with the load cables that suspend the catenary wires and undertake power transmission.

If the railway system is the human body, then catenary cables are the blood vessels that transmit blood—that is, electricity—for the system. Therefore, the completion of the first catenary cable is a key process in the railway construction, and its erection quality can directly impact the power-receiving quality of trains.

2020 will be the final year of the Jinhua-Taizhou Railway construction. Every bit of progress is significant. Although it was the New Year's Day holiday on the day of construction, the operators voluntarily gave up their vacation. As early as 6 a.m., 25 workers had assembled at the site. The site is located in the mountains, and the outdoor temperature is less than 0 °C. In order to keep warm, workers had to wear at least five pieces of clothes.

Feng Haowei, the secretary of the Party of the railway line project department, said that in order to meet the construction progress deadlines, racing against time is their usual work style. The first cable is 919 meters in length. It relies on track traction to install trains, and it applies a small tension pay-off method. The erection finished in an hour.

In the hope that the first cable erection worked well and could play as an exemplar, the construction team planned for a long time, organized specialists to conduct a thorough investigation of the site, formulated detailed plans and safety measures, and carried out with meticulous attention on-the-job training in skill and safety. The erection of the first cable laid a good foundation for the subsequent catenary construction.
