Constant Wattage Heating Cables – Heat Tracer (RHT)
Our RHT rail heater heating cables are parallel resistance, constant wattage heating cables designed for use on mainline switch systems, electrified third rails, monorails, and tramway systems.
The RHT constant wattage heating cable is a cut-to-length cable designed to keep systems free of snow and ice, ensuring operational track integrity in winter conditions.
When used for spot heating systems, the RHT is intended to be pre-terminated in 3m, 4m, 5m, and 6m lengths to match switch dimensions.
This heating cable is designed for use with standard, railway-approved heater fixing clips.
A thermally insulated end cap is available if required.
Please contact us for any specific requirements.
