Two megatrends are driving cable construction in Germany: the energy revolution, which requires the expansion and strengthening of power grids, and digitalization, which brings fiber optics to every household. Both require qualified civil engineering. Klefenz GmbH carries out underground cable installations for energy suppliers, municipalities, network operators and telecommunications companies — in Baden-Württemberg and beyond.
The classic digging method is available for paved surfaces and intersections as well as the use of cable plough for dirt roads, agricultural areas and areas where surface-friendly installation is required. Klefenz chooses the most technically and economically viable method for each section of the route.
Klefenz is qualified as a DVGW-certified pipeline builder for drinking water and gas pressure pipes (GW 301, GW 381). In cable construction, the company applies the same care: precise inventory documentation, georeferenced measurement points and complete handover of the lines to the network operator. Clients can rely on documentation that is suitable for subsequent network operation.
For municipalities, Klefenz is a reliable partner for civil engineering measures in the utility sector: underground cables for street lighting, medium-voltage connections between distribution stations, fiber-optic empty conduits for broadband expansion and house connection lines in FTTH expansion. Klefenz knows the requirements of public sector clients and how to coordinate with other supply providers in pipeline construction.
As authorized signatory, Cüneyt Özer heads the cable construction division at Klefenz GmbH. With his many years of experience in coordinating pipeline construction projects for energy suppliers and municipalities, he is the right partner for your request — whether it's a small local connection or a large broadband expansion. Get in touch, we will be happy to make you an offer.
