What is a rail transit cable?

Rail transit cables refer to signal transmission cables, electric traction cables, etc. used in the field of rail transit, including railways, urban subways, and light rail,  It occupies an important position in the construction process of railways, urban subways, and light rail, and has a significant impact on the safe and stable operation of railways, subways, and light rail.

Rail transit cable performance

Rail transit cables used for signal transmission specifically include special signal cables and ordinary signal and communication cables. Special signal cables are used in ordinary signal.  Technical upgrading products based on communication cables have better performance in signal transmission, same frequency and cable transmission, corrosion resistance, flame retardancy, and other aspects,  It better adapts to the trend of continuous railway speed increase and stable development of high-speed railway, and has an important impact on the safe operation of the track.

What standard cables do rail transit require?

The power cables used in rail transit will mainly include DC traction cables, flame retardant cables, fire resistant cables, green environmental protection cables, automatic temperature control cables, and other special cables.  Signal cables are mainly concentrated in subway, signal and control cables, communication cables, communication optical cables, and other varieties. Leaky coaxial and RF cables are mainly used in wireless communication systems.
