High-speed rail contact network with multi-core control cable market has broad prospects


At present, China's accelerated development of high-speed railways is building an increasingly dense railway network, and is also weaving an increasingly long cable network.

In July 2016, the National Development and Reform Commission issued the “Medium and Long-term Railway Network Plan”. According to the plan, by 2025, the scale of China's railway network will reach 175,000 kilometers, including about 38,000 kilometers of high-speed railway. By 2030, the scale of the high-speed railway network will reach 45,000 kilometers, connecting major capital cities and other large and medium-sized cities with a population of more than 500,000. As an important carrier of high-speed railway power transmission, multi-core control cables for contact networks have also become the main artery and lifeline of rail transit.

In high-speed operation, a powerful current supply requires high-speed rail transmission lines to achieve safe and reliable current transmission in a short period of time, while control cables are advantageous. This is one of the reasons why high-speed rail transmission lines mainly use copper core control cables. In addition, the copper core control cable has excellent resistance to stretching, shrinkage, creep and fracture, as well as excellent flexibility, corrosion resistance, ductility, etc., and can meet the stability and reliability of high-speed railway in various climates for a long time. Running, and this is far from the aluminum cable.

In short, the rapid development of high-speed rail will bring unlimited business opportunities to the cable industry.
