Modular, series-connected heating unit for railway points or switches, includes shaped aluminum casting containing tubes carrying heating fluid

摘要

In the cover box (1), channels (4) for the heating fluid are formed as a number of heating tubes. They are embedded in a casting (3) made from material of high thermal conductivity, preferably aluminum, which matches the rail profile. The cover box is constructed in the form of known, modular, series-connected units.
