The Swedish Transport Administration
Ice, snow and cold are a constant problem for rail traffic in the winter. That is why the Swedish Transport Administration contacted Ebeco for help. Together they started what became Ebeco Industri's biggest project to date: fitting more than 800 sets of points with heating systems for the winter.
It is no exaggeration to say that ice, snow and cold have caused real problems for rail traffic in Sweden in recent years. Much can go wrong in the Swedish climate in winter. Fallen conductor lines and defective trains are just some of the problems. The Swedish Transport Administration is the body responsible for building, operating and maintaining Sweden's railways, and perhaps their biggest track problem is points that freeze up in the winter.
Heating cables to meet tough demands
The Swedish Transport Administration contacted Ebeco and this was the start of what became Ebeco's biggest project to date. Many technical details needed to be determined and every part of the Swedish Transport Administration's specification of requirements had to be met before Ebeco's El-Point system was ready for use. Among other things, the Swedish Transport Administration wanted a system that could melt 40 cm of snow an hour and work in temperatures as low as -25 degrees. It also had to withstand the wear caused by regular heavy traffic, as well as the salt, oil, various cleaning agents and dirt that the railways are exposed to. When it became clear that Ebeco's system met all the requirements, the real work started.
The collaboration between Ebeco and the Swedish Transport Administration extends over a ten year period, during which time more than 800 sets of points are being equipped with the heating system. El-Point is a complete heating solution for railway points using constant-output heating cables and has a very high level of efficiency compared with other points heating systems. Thanks to the high level of heat radiation and thermally insulating cover, a large section of rail is heated and acts as a heating element, so that collected snow melts easily, even between the fixed and moving rails in the open position.
