New technologies, materials and approaches for overhead lines
Overhead Lines (OHL) play an important role in the electricity business. They are the oldest and – till today – the most common used transmission method worldwide to transport electrical energy, and especially to transport bulk energy over big distances on land. Extra high voltage lines may exceed a route length of 1.000 km for the transport of several 1.000 MW per electric circuit in alternating (AC) or direct current (DC), up to voltages of 1.150 kV. OHL will be designed to build up new grids or to improve and strengthen existing grids.
