Cables are the connecting arteries of our modern times. Anyone who wishes to move either energy or information has only one choice - cables.
invatec is a renowned enterprise also in the sector of plastics engineering and has been developing and manufacturing cable ducts made of synthetic materials since 1997. Invatec’s innovative cable ducts demonstrate their advantages already during transport and installation or when it comes to the entire logistics process.

Installation step 1 Placement of the cable ducts in the cable route prepared beforehand 
Installation step 2 Fixation of the cable duct with specific ground anchors depending on local requirements 
Installation step 3 Lid installation 
Installation step 4 Filling of the cable ducts When building industrial and infrastructural facilities, you quite often have to expect rough and topographically difficult terrain to deal with. But even under such circumstances, the installation of cables should not cause any problems, provided that you use the VARIO TOP pillar-mounted cable duct system.
VARIO TOP is a high quality and at the same time multi-functional cable protection system with a comprehensive range of accessories available. Special elements are available on request.
The Federal Railway Authority has certified the VARIO TOP pillar-mounted system in sizes 1, 1a, and 2 .
Certification nos: 2152lbzb (21/98), 2152lbzb (21/99) und 2152lbzb (015/01)
The cable duct is extremely light and at the same time solid. It is easy to install and offers reliable protection for sensitive cables and leads against any influence from the outside – also in topographically difficult terrain.
The rugged system allows for all forms of pillar mounting. Uneven ground surface, slopes and inclines, bends – no problem for VARIO TOP. What you will get is a maximum of flexibility when it comes to cable protection and ease of installation.
Three different variants are available: Size 1, Size 1a and Size 2.

Installation step 1 The pillars are rammed in after measuring 
Installation step 2 The mounting plates are installed, adjusted and bolted onto the pillars 
Installation step 3 The cable ducts are positioned and bolted onto the mounting plates 
Installation step 4 After the insertion of the cables, the lid will be closed with the quick-action fastener Heavy and bulky concrete slabs (weighing approx. 200 pounds each) have so far generally been employed when constructing service roads in the framework of civil engineering projects of world wide rail industries. Since their installation, however, presents various disadvantages, a novel alternative to gravel mounting plates made of concrete was developed.
invatec’s gravel mounting plates consist of panels (2,000 x 250 mm) that are made of glass fibre reinforced plastic (GFRP or GRP). Simple installation together with a low weight (only about 20 lbs per panel) are their essential benefits. HEB 100 double-T steel profiles are used as supports into which the GRP panels are inserted.

Installation nearby the railroad track The performance portfolio of invatec also includes innovative signal foundations. Signals are crucial control elements in railway and road traffic. They are the prerequisite for the optimal safety of traffic users. Standard masts with and without gantries are employed for civil engineering projects of DB AG. A solid foundation for the signal is essential here.
Our »TECDOWN« piling tube foundation is approved for all signals used by and all route categories of DB AG and is equally suitable for maintenance as well as new construction projects.
This system for signal foundations has reached its final development stage after a development process of about two years and the production of various prototypes used in facilities of DB Netz AG. The signal foundation "TECDOWN" is protected for the inventor by patent and trademarks. After undergoing comprehensive tests and completion of the certification process with the Federal Railway Authority, this signal foundation has reached commercial maturity.
The adapter sports a corrosion protection acc. to ZTV-ING, Part 4, with hot-dip galvanization acc. to DIN EN ISO 1461 as well as an intermediate and top coating acc. to the TL/TP-KOR for steel structures, Page.87. For process-related reasons the contact area with the mast base features only a hot-dip galvanization. If specific requirements apply regarding corrosion protection (for example traction) the adapter may be equipped with an additional protective isolation coating. Loads may be applied after curing of the casting as soon as 60 % of the standard strength of a C25/30 has been reached, provided that adapters are used.
The production of foundations for driven piles makes comprehensive interventions in the pressure area of the tracks unnecessary. In addition to the effect that the existing soil structure is hardly affected, the negative effects on the operation may also be reduced on account of the quicker construction process – more than 75 % in comparison with individual foundations made of prefabricated concrete elements. Please note that this reduction of the negative effect on the operation also includes the considerable passive construction costs such as for example securing operations, deactivation and earthing of overhead traction lines, construction supervision, preparation and implementation of the necessary paperwork as well as expenditures for a lack of route availability (railroad traffic speed reductions, detours, alternative transport etc.).
