We develop our LPOF solutions in close cooperation with our customers. This allows us to provide quick and therefore cost-efficient installation of appropriate transition technologies. Although some oil cable systems (LPOF) have already been in use for more than 70 years, they can still provide many more years of operation if they receive appropriate and regular maintenance. In the meantime, it is possible to renew such cable systems section by section, since NKT provides solutions for connecting low-pressure oil-filled cable systems with modern XLPE systems. Our reliable and cost-efficient transition joint portfolio also includes a broad range of solutions for connecting gas pressure cables to XLPE cables.
