Operating Principle

Power Collector

When the bogie pantograph is retracted in rest position:

…the power collector in the upper position is unable to activate

the power line segments; the pulling force is not enough to lift

up the belt

The vehicle can run over the line in coasting without activating

the segments

All the segments are not energized and connected to ground

Operating Principle

When the bogie pantograph is released:

…the power collector is in contact with the segments and its

magnetic force attracts the flexible ferromagnetic belt, that push

up the internal movable conductive contacts, allowing the

closing of the electric circuit and the power transmission from

the segments, in contact with the collector, to the vehicle

TramWave: main benefits for sustainable

urban mobility

• Make the urban context more liveable, removing the visual impact of overhead

catenaries and poles from squares, buildings, monuments, historical areas, etc…

• Continuous power transmission from contact line to vehicles without any

interruption/charging times (for both traction and auxiliaries)

• No need of on-board big and heavy storage energy systems (supercapacitors)

• No need of electronic devices or induction systems

• The closing of the traction electric circuit doesn’t foreseen the use of the tracks no

more problem due to the effects of stray currents, preserving the underground utilities

(water and gas pipelines, electricity network underground cables, etc…) and the rails

from electrolysis effects less maintenance costs.

• Possibility to have a mixed power-supply system, by mean having Tramwave and

traditional catenaries on the same tramway line (ex. Tramwave in the historical centres

and catenaries in the suburbs), moreover it’s possible to feed with Tramwave rubber

tired vehicles like busses

• Regenerative Breaking and energy saving
