EINLWL GRP-Cable Duct System

In Germany the DB Netz AG in collaboration with DB Systel created a specification for a cable duct system in glass fibre-reinforced plastic. As the system had to be in- stalled in the ground and elevated it made sense to work with the already well known glass fibre-reinforced plastic (GRP). Due to rough and difficult terrain conditions or tight spaces, it is not always possible to install conventional concrete cable duct systems. In such cases the EINLWL- system is an option. The EINLWL-system must protect and be able to carry one fibre optic cable with 60 fibres.

This cable corresponds to a diameter of 25 mm. The cable duct system must be designed for an elevated and in the ground installation. The specification provides a minimum distance between the supports of 2 metres. The present system was laid out for a 3 metre span. Therefore a structural analysis was done and rechecked by an inspecting structural engineer. Practical tests were done together with DB Systel and the installer - company Andreas Mühlbauer GmbH in Saalfeld according to the specifications of DB Systel. In early 2011, a first test track of 8 km was installed for the German Orlabahn.

  • 3 METRE SPAN SNAP-IN LID EASY TO INSTALL
  • USABLE CROSS SECTION 53 X 56 MM
  • EINLWL GRP-CABLE DUCT SYSTEM WITH GLASSFABRIC REINFORCEMENT MANLOAD 140 KG
  • FEW PARTS

The installation of the EINLWL system is highly efficient. The system consists of 1 galvanized steel square tube, 1 galvanized steel connection plate, GRP cable duct base and lid. The elevated system only needs one bolt every 3 metres. The connection plate is bolted to the square tube. The 3 metre long GRP cabled duct base is only inserted into the connection plate. The 3 metre long GRP lid snaps in the GRP cable duct base without any additional fixings. The installation in the soil is fixed with 2 soil nails. This allows the use of very few parts on the construction site, therefore achieving a high operating efficiency. Due to the 3 metre span, one third of ramming and connections plates can be saved.

EINLWL GRP-Cable Duct System

In Germany the DB Netz AG in collaboration with DB Systel created a specification for a cable duct system in glass fibre reinforce plastic.
 
As the system had to be installed in the ground and elevated it made sense to work with the already well known glass fibre-reinforced plastic (GRP). Due to rough and difficult terrain conditions or tight spaces, it is not always possible to install conventional concrete cable duct system. In such cases our EINLWL-system is an option. The EINLWL-system must protect and be able to carry one fibre optic cable with 60 fibres. This cable corresponds to a diameter of 25 mm.
 
Our EINLWL cable duct system is designed for an elevated and in the ground installation. And our present elevated system was laid out for a 3 metre span. The system allows the use of very few part on the construction site, is easy to install and solid, therefore achieving a high operating efficiency.
