Rails and switches are easily covered by snow and ice. When rails and switches are frozen, accurate train rerouting cannot be achieved, severely affecting the safe operation of the railway. Snow and ice coverage on the rails reduces friction between the rails and wheels, impacting control of the train and posing significant safety risks. Manually removing snow and ice is inefficient, costly, and still cannot prevent railway accidents. Snow removal and frost prevention in the railway system is an urgent issue. An electric heating solution for rails is a feasible method for removing snow and ice from rails and switches.

Guidelines for designing a heated rail scheme:

· Choose high-power output electric heat tracing systems.

Choose an appropriate installation location to maximize efficiency.

· Ensure adequate heat transfer to the rail.

Wuxi Global Electrical Equipment Co., Ltd. has designed technical solutions for constant power series, parallel, and skin effect electric heat tracing, based on existing products and technologies. It integrates installation accessories suitable for rail tracks and employs advanced control systems to launch the rail heat tracing system. See the illustration below for details, with the specific implementation to be designed and installed according to on-site conditions.

Highlight the intelligent temperature measurement line.

Suitable for heating and auxiliary heating of railway switch tracks.

Single type product can meet all application needs.

Cuttable and easy to install.

Low maintenance requirements.

Rails Skin Heating Solution:

Output power: 1~300 W/m

Single power circuit reaches up to 15,000 meters.

Long single power heating length

Low operating costs.

Low maintenance costs;

Compared to other systems, the rail skin electrical heating solution consumes less energy and achieves a higher surface temperature on the rail; it also has lower maintenance costs, making it a recommended choice.

The above three options are all equipped with intelligent systems:

The intelligent centralized control system can monitor the operation of the heating belt in real-time.

Displays the temperature of the track every meter and accurately locates the fault point when the auxiliary heating system fails, facilitating timely troubleshooting.
