China’s railway infrastructure investment is 700 billion yuan, the new line is tracked 7,935 kilometers, the double track is 6,211 kilometers, and the total mileage of high-speed railway operations exceeds 13,000 kilometers, initially forming a high-speed rail network with wider coverage and greater effect. The investment in such a large infrastructure will certainly drive the demand for related electrical products. It will use a large amount of power cables, and the wire and cable industry will also share a large amount of cake. Experts suggest that relevant companies must first investigate the traction power supply system to enter the electrified railway market. China's electrified railway adopts power frequency single-phase AC electric traction system, rated voltage is 25kV, and traction power is electric energy. The traction power supply system transforms the electrical energy delivered by the national power system into a form suitable for the use of electric locomotives. The electric locomotive completes the traction task. Therefore, traction power supply equipment and electric locomotives are two major equipments for electrified railways. The use of power cables will be very large, and other railway equipment and infrastructure should be adapted accordingly. Considering the extraordinary construction environment and use of high-speed railways, most of the power cables used require low-smoke, low-halogen, flame-retardant, fire-resistant, oil-resistant, ultraviolet-resistant, moisture-resistant, waterproof, mold-proof, rodent-proof, etc. Termite-proof. High- and low-voltage power cables, low-smoke halogen-free cables, mica-insulated fire-resistant cables, mineral-insulated fire-resistant cables, leaky coaxial cables, etc., which are suitable for hot and humid climates in the south and multiple ant environments, will have good market opportunities. Construction of metro tunnels, subway stations, equipment installation, and firefighting requires a large number of power cables (railway traffic is usually powered by strong power), communication cables, extraordinary cables for tunnels, and leakage and RF cables. Lighting wires and cables for tunnels and subway stations are also a major attraction. For the construction of high-speed passenger dedicated lines, according to the current technology, orbital transponders will be used in large quantities, which provides a vast market space for orbital transponder data transmission cables. The power cables in the high-speed railway construction cables will mainly be special cables such as DC traction cables, flame retardant cables, fire-resistant cables, green environmental protection cables, and self-control temperature cables. The signal cable is mainly concentrated in the subway, signal cable and control cable, communication cable, communication cable and other varieties. Leaky coaxial and RF cables are mainly used in wireless communication systems. Therefore, in the tide of construction of the "Twelfth Five-Year Plan" high-speed railway, domestic wire and cable companies have reason and strength to bear the future.
