Planning/Engineering Engineering 4.0 we are planning the power grid of the future

 

What makes VD Hochspannungstechnik special

Profit from our decades of experience in the field of power grids and power generation plants, which we have been realizing with technology of tomorrow. Engineering 4.0 makes us a leading consultant in state-of-the-art technologies. In addition to the digitalization of plants and networks, we work accurate with 3D Models. We support you in securing your power supply or covering your additional temporary requirements at short notice. Our engineering office offers you services according to the Fee Structure for Architects and Engineers (HOAI). Of course, in addition to full project support, we also provide partial services if required.

ELECTRICAL NETWORKS/ POWER LINES

(2D and 3D Routing Models)

VD Hochspannungstechnik supports you in the execution of new Overhead Transmission Line or Uprating Projects and the implementation of advanced state-of-the-art online monitoring technologies for existing and future OHTL’s.

We take away your worries of replacing existing gas and oil pressurized cable systems with new XLPE cable technologies reinforced with cutting-edge online monitoring systems that increase transmission capacities and reliability.

We implement cable transition compounds & routes of high voltage overhead lines and eliminate overhead lines in urban areas to create more living space in the fast-growing cities.
