Catenary(Railway) structure systems are a set of carrying
cables and conductive wires intended for supplying
electrical means of transport with current collection by the
aerial device. Railway catenaries and portals carry the
overhead line system through which the electric energy
necessary to operate the catenary system that trains used
is transmitted. The catenary is used to run most trains and
trams, but also trolleybuses.
DEMKA can provide catenary structures according to the
customer’s request.
