Constant Power Parallel Track Electric Heat Tracing System

Rails and switches are easily covered by snow and ice. When rails and switches are frozen, accurate train rerouting is not possible, severely impacting the safety of railway operations. Snow and ice covering the rails reduce friction between the rails and wheels, affecting train control and posing significant safety hazards. Manual snow and ice removal is inefficient, costly, and still cannot prevent railway accidents. Snow removal and frost prevention in the railway system are urgent issues. The electric heating solution for rails is a solution for removing snow and ice from rails and switches.

Guidelines for designing a heated rail scheme:

·Choose high-power output electric heating cables.

·Choose an appropriate installation location to maximize efficiency.

· Ensure substantial heat transfer to the rails.

Wuxi Global Electrical Equipment Co., Ltd. has designed technical solutions for constant power series, parallel, and skin effect electric heating, integrating installation accessories suitable for tracks, and utilizing advanced control systems to launch the track heating system. Please refer to the image below for details, and the specific implementation can be designed and installed based on the on-site conditions.
