3rd Rail Heating
A third rail is a method of providing electric power to a railway train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track.
During periods of cold weather the 3rd rail can become iced over which restricts the flow of electricity from the 3rd rail to the train, this results in the train being unable to move from a stationary position.
Trace Heating Projects Design, supply and install self regulating heaters to prevent this happening in cold temperatures
Self-regulating heaters, being of a parallel circuit configuration, can be cut to length on site, they can adapt to different rail temperatures along the same circuit length. The heater will draw more power at the more exposed end of the circuit when compared to the other end of the same circuit, therefore reducing electricity cost for a more energy efficient system, heaters are available in various voltages from 12 V to 1000 V.
