Power Transmission & Distribution
Overview
Power Transmission & Distribution
Energy is a valuable asset.
Sustainable utilization of this resource is based on two premises: efficient, environmentally friendly energy generation in modern power plants and safe, low-loss transmission of electricity and heat from power plants to consumers using highly efficient transport and distribution systems.
ILF offers optimized, state-of-the-art solutions for a wide array of energy transmission services, from the transmission of electrical power via the energy suppliers’ overhead transmission lines to industrial supply systems that place great demands on the system layout and configuration because of special load characteristics.
ILF is a pioneer in implementing innovative power transmission systems based on direct current transmission with HVDC cables or alternating current transmission with gas insulated transmission lines (GIL). These systems connect high-capacity energy generation facilities to the grid over long distances.
