Two megatrends are driving cable construction in Germany: the energy transition, which requires the expansion and reinforcement of power grids, and digitalization, which is bringing 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.
We use traditional excavation for paved surfaces and intersections, and cable ploughing for dirt roads, agricultural land, and areas where surface-friendly installation is required. Klefenz selects the most technically and economically viable method for every section of the route.
Klefenz is a DVGW-certified pipeline builder for drinking water and gas pressure pipes (GW 301, GW 381). We apply that same level of care to cable construction: precise inventory documentation, georeferenced measurement points, and complete handover of the lines to the network operator. Clients can rely on documentation that is fully prepared for ongoing network operations.
For municipalities, Klefenz is a reliable partner for civil engineering in the utility sector: underground cables for street lighting, medium-voltage connections between distribution stations, fiber-optic conduits for broadband expansion, and FTTH house connections. Klefenz understands the requirements of public sector clients and how to coordinate with other utility providers during pipeline construction.
As an authorized signatory, Cüneyt Özer heads the cable construction division at Klefenz GmbH. With his many years of experience coordinating pipeline construction projects for energy suppliers and municipalities, he is the right partner for your inquiry — whether it is a small local connection or a large-scale broadband expansion. Get in touch; we would be happy to provide you with a quote.
Whether it is a demanding construction project or a professional perspective – Klefenz stands for experience, reliable collaboration and a clear commitment to quality. If you would like to realise a project or become part of our company, we look forward to speaking with you and taking the next step together.
