ACIM Tension stringing

Catenary Installation

ACIM - Advanced Catenary Installation Method - is the most advanced working system for stringing the catenary (contact wire + supporting wire) of an overhead contact line, for electrification of railway infrastructure. This method allows you to carry out simultaneously, and in the shortest time possible, all the working phases. It is used both for the electrification of "new railway lines" and for the "renewal of the catenary".
The stringing system guarantees the control on the individual stringing forces applied to the conductors, from the beginning to the end of the operations, without stressing or twisting the conductors. Tesmec Constant Tension Stringing Unit assures the highest tension accuracy, even in case of variation of towing direction, speed, air temperature and slope.
