EHV/HV cable systems: your capable partner for underground high voltages

Close to cities, industrial areas, wind farms – everywhere, where EHV/HV voltages cannot be transmitted via overhead lines, that's where underground cables are used. Just as for overhead line construction, we are also a skilled and experienced partner in constructing EHV/HV cables systems.

We have expertise in planning, supplying, installing and commissioning transmission lines. We reliably realise projects all over Germany — whether it's in partial deliveries or a complete package. We are also at your disposal for maintenance tasks and for fault clearing.
