Innovative developments and solutions for steel lattice towers

Meeting the new standards

The increase in renewable energies and the progress in telecommunication technologies (e.g. G5) require the construction of new and/or the reinforcement of existing transmission lines resp. telecommunication towers.

The European Network of Transmission System Operators for Electricity (ENTSO-E) expect 18.000 km of new transmission lines to be constructed in Europe until 2035 to cover the demand of renewable energies.

Weight reduction using S460

Steel lattice towers made of fully recyclable hot-rolled angles profiles are a typical solution for transmission and telecommunication towers.

The use of high strength steel (e.g. S460) in steel lattice towers reduces the weight of standardized towers up to 20% compared to normal steel grades (e.g. S355), leading to lighter structures which are easier and faster to erect.

Innovative solutions

The reinforcement of existing steel lattice towers with carbon fiber reinforced polymers (CFRP) strips increase the resistance of the main bearing elements by 50% and allow a quick and easy upgrade of the towers to higher voltage and bigger G5-antennas.

The workshop informs on the latest research results in the field of steel lattice towers followed by presentations on current technical innovations in steel towers based on results from steel applied research.
