Underground power cables: invisible technology

Underground power cables encounter a variety of infrastructures. This is where the challenges lie in power cable design – alongside calculating the thermal and electrical design loads. We advise our clients on technical solutions for underground power cables.

One important factor with high-voltage power cables is the temperature of the cable. We calculate the thermal properties of cables in conjunction with mechanical and magnetic issues – for example, as part of an alternatives study or basic design. We design, advise on and perform design reviews of the electrical engineering, energy engineering and mechanics.

We provide the following services:

  • new constructions
  • feasibility studies
  • maximum load calculations
  • cross-bonding
  • magnetic field studies
  • EMC studies
  • temporary power cables
  • line-cable terminations
  • groundings
