Third rail systems are a means of providing electric traction power to railway trains, and they use an additional rail (called a “conductor rail”) for the purpose. On most systems, the conductor rail is placed on the sleeper ends outside the running rails, but in some cases a central conductor rail is used. The conductor rail is supported on ceramic insulators or insulated brackets, typically at intervals of 10 feet (3 meters) or so.
Rahee manufactures and supplies these galvanized steel brackets, used as a component for a Support Insulator Assembly for an electrification system dedicated to Metro application. The bracket is an interface between the guide way and the insulator. Its function is to hold and locate a conductor rails with reference to a running rail. The brackets are fabricated as per client specifications and drawings specific to each project. Usually the brackets are fabricated using hollow square pipes and thereafter Galvanized finished for dispatch.
Rahee manufactures various types of brackets :
- Line Bracket Support for Viaduct
- Ramp Bracket Support for Viaduct
- Line Bracket Support for Turnouts
- Ramp Bracket Support for Turnouts
