Rails and switch points are prone to being covered by snow and ice. When rails and switch points are frozen, accurate train rerouting is not possible, severely affecting the safety of railway operations; when covered with snow and ice, the friction between the rail and the wheel decreases, affecting train control and posing significant safety risks; manual snow and ice removal is inefficient, costly, and still cannot prevent railway accidents. Snow and ice removal and anti-freezing in the railway system are urgent issues to be addressed. The rail electric heating solution is a method to remove snow and melt ice from rails and switch points.
Design Principles for Rail Heat Trace Solutions:
· Choose high-power output electric heating cables.
· Choose an appropriate installation location to maximize efficiency.
· Ensure adequate heat transfer to the rail.
Wuxi Global Electric Equipment Co., Ltd. has designed technical solutions for constant power series, parallel, and skin-effect electric heating, based on existing products and technology. Integrated with installation accessories suitable for rails, and utilizing advanced control systems, we have launched the rail heating system. See the illustration below for details; the specific implementation can be designed and installed according to the on-site conditions.
