Our innovative high-voltage coaxial cable enables the efficient and environmentally friendly transmission of power in the multi-gigawatt range. This technology allows for low-loss power transport over long distances ideal for applications such as supplying entire regions with renewable energy or connecting remote generation plants. A key innovation is that no measurable magnetic or electric fields exist outside the cable, and in the unlikely event of a failure, no environmentally harmful substances can leak.

​

The coaxial arrangement of inner and outer conductors eliminates electromagnetic fields outside the cable a well-established physical principle that has previously been difficult to implement due to technical challenges. Earlier solutions relied on hollow inner conductors with pumped oil for heat dissipation, which posed significant environmental risks because the oil had to be kept under high pressure for dielectric reasons. Additionally, these systems did not provide complete protection against external electromagnetic interference.

​

Our high-voltage coaxial cable solves these problems with an innovative technology: the space between the inner and outer conductors is filled with stearin, which provides excellent insulation while simultaneously enabling efficient heat dissipation. In the unlikely event of a leak, the stearin only escapes in limited amounts and solidifies shortly after the leak site without harming the environment.

This groundbreaking technology not only enables safe and sustainable energy transmission but also protects sensitive environments from harmful electromagnetic emissions, opening new prospects for the power infrastructure of the future.
