Rigid catenary systems
The clonventionally used pair of contac and catenary wire can be replaced with an aluminium profile and a contact wire inserted in it. The stiffened catenary construction makes it possible to use in places with limited access and gauge. The installation of the catenary on movable arms allows it to be moved sideways or up. By making a rigid catenary in a movable version, the work becomes easier and much safer. The rigid catenary requires, in cooperation with typical pantographs of rail vehicles, a much smaller structure height, which is why it is often used in tunnels and bridges.
Maintenance depot
- Safe and convenient access to the roof of the vehicle and the ability to operate overhead cranes and winches in their full range (due to possibility to move the catenary to the side)
- Possibility to use lifting jakcs on a track equipped with a retractable rigid net
- Interlocking with the depot equipment
Tunnel, bridge
- Less height of the suspension structure, what saves the costs by reducing the height of the tunnel
- Lack of a catenary tensioning system simplifying the design and execution process
- Simpler and faster maintenance of scheduled and emergency catenary repairs (mainly due to lack of tension)
Station, terminal
- Less impact on the structure of the building (no need to tension the catenary)
- Aesthetic aspects
- Fast repair time and lower maintenance costs
- Lower maintenance costs and shorter repair time
- Compact design, not requiring much space for construction components
- Enable safe access to the roof of the rail vehicle after retracting the catenary. Free operation of hoists, overhead cranes and lifting jacks
- Possibility of reducing the height of the service depot or tunnel at the stage of construction – the necessary gap between the network and the roof / ceiling is only 300 mm – reduction of investment costs
- Higher current carrying capacity and short circuit strength in comparison with conventional catenary
- Higher acceptable contact wire wear, with no contact between the pantograph and the aluminum rigid profile.
- Equivalent Cu cross-section of aluminium profile is even several times larger than in conventional catenary
- Possible reduction of the number of auxiliary power feeders
- Simplification of the structure and limitation of the number of assembly elements
