2011 China's railway infrastructure investment 700 billion yuan, laying 7935 km of new lines, laying 6211 km double-track, high-speed rail operations will exceed the total mileage of 13,000 km, the initial formation of wider coverage, greater effects of high-speed rail network. Such a large infrastructure investment, will boost demand for related electrical products, will make extensive use of power cable, wire and cable industry will also share a great piece of cake.
Experts suggest, and the enterprises to cut into the market, we must first study electrified railway traction power supply system. China's electrified railway using frequency single-phase AC electric traction system, rated voltage 25kV, traction power to electricity. Traction power supply system power state changes in the power transmission system for use in the form of electric locomotives. Electric locomotive traction is to complete the task. Therefore, the traction power supply equipment and electric locomotives are the two main electrified railway equipment, the use of power cables will be very large, railway equipment and other infrastructure should be corresponding.
Taking into account high-speed railway construction and the use of the extraordinary nature of the environment, most of the requirements of smoke with no power cables (low)-halogen, flame retardant, fire-resistant, oil resistant, UV-resistant, resistant to moisture, water, mold, rodents, etc., also called the South termite. Hot and humid weather for the South and more ants environment of high voltage power cables, low smoke zero halogen cables, mica insulation fire-resistant cable, mineral insulated cable fire, leakage coaxial cable, etc., will have good market opportunities. Subway tunnels, subway stations, equipment installation, fire and other construction requires a lot of power cable (usually a strong electric rail way power supply), communication cable, tunnel and cable leakage and exceptional RF cables. Tunnels and subway stations with the lighting wires and cables is also a highlight.
The construction of high-speed passenger line, according to current technology, the transponder will track large-scale use, which track the transponder for the data transmission cable to provide a broad market space. Cable high-speed railway construction will be mainly in the DC power cable pulling cable, flame-retardant cables, fire-resistant cables, green cable, Self-Regulating cables special cables. Signal cable mainly used in the subway, signal and control cables, communication cables, communication cables and other varieties. Leaky coaxial RF cable is mainly used in wireless communication systems.
Therefore, in the "five" high-speed railway construction tide of domestic wire and cable companies have reason to have full strength for the future vision.
