After a period of long and extensive consideration with authorized personnel of ÖBB and DB Netz Castioni Kunststoffe have developed an elevated cable troughing system made in lightweight glass fibre reinforced plastic (GRP) for a maximum distance between two steel posts of 6 metres. From the beginning we have focused on a safe, stable and easy to install system taking into consideration that in many parts of Europe an elevated cable troughing system must sustain snowfall or snowdrift horizontal and lateral. The system is easy to install because of the float-mounted GRP cable duct trough. The system offers ARCOEINS with an internal width of 100 mm and a internal depth of 150 mm, weighing 5.6 kg per meter. ARCOZWEI has an internal width of 250 mm and a internal depth of 150 mm weighing 8.20 kg per meter. The cover snaps easily in to the trough giving greater security for cable theft. The system is stable due to the double-walled construction and the glass fiber fabrics of the trough. A full range of steel supports are available.
