The elevated GRP cable duct system ARCOEINS and ARCOZWEI was designed for topographically difficult terrains along the rails. Even in such conditions the installation of cables does not present a problem.
ARCOEINS has a inner cross section of 100x150 and ARCOZWEI 250x150. The system allows a maximum distance of 6 meters between the sigma posts. The GRP cable duct is extremely light, yet solid due to the double walled construction.
