Protection of point heaters

Point heaters are indispensable for smooth railway operations, especially in regions with cold winters. Blocked or frozen points can significantly disrupt railway traffic or even bring it to a standstill. Thanks to the targeted heating, the points remain manoeuvrable and controllable even in extreme weather conditions.
With protection solutions from DEHN, you can implement lightning protection, earthing and surge protection for point heaters in a holistic and efficient manner.
