Constant Power Series Track Electric Heat Tracing System

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.
