Custom hybrid cable in record time for the autobahn
Custom hybrid cable delivered to the BAB 3 motorway in record time
The BAB 3 motorway runs from the Dutch border through the Rhine-Ruhr and Rhine-Main regions to the Bavarian-Austrian border near Passau. It is one of the most important federal motorways. The connection between the Biebelried and Fürth/Erlangen motorway junctions is also of great importance for regional traffic in northern Bavaria. With the growing volume of traffic, the number of accidents and the risk of congestion have also steadily increased. For this reason, the 76-kilometre stretch will be expanded to six lanes by A3 Autobahn GmbH in a public-private partnership (PPP) by 2025. To ensure that emergency telephones and roadside facilities can remain in operation during the construction work, Bayka delivered 92 kilometres of multisystem cable with 12 fibre optic strands as the central element and 6 copper quadruples for telecommunications transmission in record time.
Challenge
In 2020, construction progress on the A3 motorway depended on the delivery of this specific cable. Why? The existing emergency telephones had to remain in operation under all circumstances, despite the widening of the motorway. Every day of construction delay costs a fortune, so Bayka promised the project managers that it would deliver the temporary cable on time and in the required quality. Within a few weeks, the promise was fulfilled. The custom-made hybrid cable is just as suitable for the installed emergency telephones as it is for modern, digital telematics systems and route stations. As it is used outdoors during the construction phase, it had to be designed to be longitudinally and transversely waterproof and rodent-proof. Once construction is complete, it will be laid in pipes for further use.
Solution
Bayka is a company with short communication channels and flat hierarchies. This flexibility makes it possible to develop and manufacture customised special cables even in small batch sizes. A3 Nordbayern GmbH had set high requirements for the transmission properties of the cable. Twelve fibre optic fibres and six copper quadruples had to be implemented in one product for the telecommunications connection of the emergency call boxes. Working closely with sister and subsidiary companies, Bayka quickly found the technically optimal solution in the form of the A-02YSTF(L)2YB2Y 6x4x1.2 STI + 1×12 E9/125 outdoor telecommunications cable. In addition, the 92 kilometres of hybrid cable were delivered just in time to the various construction sites using the company’s own trucks.
