Thanks to a simulation carried out in-house by our R&D department, we have verified that it is the graphite that causes the contact wire to overheat and not viceversa.
This is why the introduction of copper contact elements significantly reduces overheating!
With this type of pantograph and by exploiting the heat dissipation provided by the aluminium profile of Gruppo Bonomi's rigid catenary, standstill currents in excess of 1000A can be achieved.

Over the years, Gruppo Bonomi has developed a number of flexible catenary solutions that guarantee minimal overall dimensions.
Rigid catenary is not the only answer to tunnels with reduced cross-sections: discover all our solutions.
ONE CANTILEVER FOR MANY TRACKS
Taking advantage of Omnia's modularity, we developed a double profile system, increasing its structural strength to allow for multi-track applications up to 15m.
Gruppo Bonomi always works with a view to cost saving and reducing environmental impact.
MAINTENANCE FREE: THIS IS OUR MISSION
Did you know that Gruppo Bonomi has developed grease-free tensioning devices?
This new allows to drastically reduce maintenance interventions, thereby optimising the post-installation costs of our systems.
Another plus? The tensioning devices with composite bushings developed by the Gruppo Bonomi have no operating temperature constraints.
INSULATION COATING: A COMPLEX PROCESS BEHIND A SIMPLE FEATURE
Gruppo Bonomi, thanks to the active contribution of EB Rebosio, has always been a leader in the production of composite insulators.
Did you know that monitoring the characteristics of the silicone over time is essential in addition to controlling process parameters,? In this way we guarantee its correct vulcanisation and consequently the ideal performance of our insulators.
