The elevated GRP cable duct system ARCOSYSTEM® was designed for topographically difficult terrains along the rails. Even in such conditions the laying of cables does not present a problem. ARCOSYSTEM® Size 1 has a usable inner cross section of 100 x 150 mm and ARCOSYSTEM® Size 2 250 x 150 mm. The elevated cable duct ARCOSYSTEM® allows a maximum distance of 6 metres between the sigma posts. Therefore a structural analysis was done and rechecked by an inspecting structural engineer. The GRP cable duct is extremely light, yet solid due to the double-walled construction of the base. The lid snaps in to the base and can only be opened with an accurate tool. 

Connection plate, sigma post and the GRP cable duct base and lid are extremely easy to install. The sigma post is rammed into the soil. Then, the connection plate is bolted together with the sigma post. Depending on the selected fixation with 2 or 4 bolts, the 6 metre long GRP cable duct base is inserted into the fixation. The 6 metre long GRP lid snaps in the GRP cable duct base without any additional fixings. As a result of this easy to install system the assembly time of the cable duct is extremely reduced. The simple and thus fast installation provides a great advantage. Overall, the GRP cable duct system presents a commercially viable alternative to conventional concrete cable ducts. Thanks to this solution, the project duration is shortened and the construction and labour costs are low. (EN)
