Underground cable installation
the clever way of power cable routing

Laying earth cables without trenches practically works everywhere

Thebasic supply of electricity requires a dense and flexiblepower cable network. However, the high material and financial expenditure for laying cables using open trench methods often prevents the electricity from getting to where it is needed. The solution is the ecologically and economically gentle NODIG construction method. With trenchless technologies, underground cable routing is possible practically everywhere: in complex urban areas or across country, in protected areas or even underwater.

Laying underground cables is safe, simple and environmentally friendly

With our NODIG systems you can install the protection pipes for medium and high-voltage underground electric cables over long distances just as easily and environmentally friendly as the service lines to the end user, even directly into the supply room. By laying earth cables without trenches, you can even realise projects that would otherwise not be feasible for nature conservation reasons or because of concerned residents. Innovative NODIG technologies and proven standards make underground cable installation easier than you think.

Advantages of underground cable laying with Nodig technology at a glance

  • Clever installation of protection pipes and power cables along roads and under traffic and waterways with short or long pipes made of all standard materials
  • Trenchless power cable routing for house connections from the pit/keyhole to the building or directly to the supply room and vice versa
  • Trouble-free realisation of the necessary installation depths for safe underground electric cable installation
  • Maximum planning and technical safety of underground cable laying according to the latest regulations
  • Precise proof and documentation of position, function and tightness of the new earth cables
  • Recognised by environmental associations as sustainable techniques with verifiably low consumption of nature capital
