REHAU systems in polymer materials have held a firm place in the area of railway power supply for many years. We develop complete systems, from idea to start of production, from our own construction kit.
However, on this level, we also implement customer-specific solutions. Live-rail supports – height adjustable and rigid – for live-rails coated from above, the side and below, live-rail cover profiles, spacers, air conditioning seals and special profiles / moldings / accessories in the broadest range of materials, cross-sections and production processes constitute elements of a comprehensive product portfolio. Even the live-rail itself comes from REHAU.
Live Rail cover systems
The REHAU range includes the broadest range of cover systems. In the development, we are always mindful of ease of installation.
Other attributes of the live-rail cover systems are:
High mechanical load capacity through to walk-on stability
High break resistance
High creep current resistance
Suitable for tunnel use
Resistant to many chemicals
Technology for the third rail from one source, including aluminum-steel composite live-rail.
The permanent joining of steel and aluminum brings a multitude of advantages. As such, there is no longitudinal slip, no minimum steel thickness, and the joint is not subject to wear or dependent on the clamping force.
Individual extrusion profile
No grinding, longer product lifetime
No weld areas / no stop marks
Consistent mechanical material properties
Higher short circuit load capacity
Greater mechanical load capacity
Ready-made, straight steel inserts
No bending of the steel shank during extrusion
No corrugated steel surface
Lower wear, longer product lifetime
Low noise in operation
Lower strain on the pantograph
Lower electromagnetic interference (EMI)
Sealing is the specialty of silicone profile solutions. Silicone foam frames are used to seal between the air conditioning air intake and the bodywork. The material combination: RAU-SIK 8018.
The program range is complemented by sheet material for water jet cut seals, sometimes with adhesive tape as an installation aid.
For seals in rail vehicle construction, unfoamed silicone solid materials are availablein RAU-SIK 8968. This material combination is certified under CEN TS 45545-2:2009, requirement set R23/24
Live rail supports
Live-rail supports in fiber-reinforced thermoset display a range of advantages not only in terms of handling and safety:
High static and dynamic stability
Less fragile than ceramic or resin insulators
Long air and creep distance as the holder and insulator are combined in one component
Significantly better electrical properties than steel holders
Low-smoke formula design possible
Balancing of threshold tolerances or different installation conditions with vertical and horizontal adjustment option
