Innovative solutions for steel lattice towers + webinar video

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 and telecommunication towers.

The European Network of Transmission System Operators for Electricity (ENTSO-E) expect 18 000 kilometres of new transmission lines to be constructed in Europe by 2035 to cover the demand of renewable energies.

Weight reduction using S460

Steel lattice towers made of fully recyclable hot rolled angle 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 standardised 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 fibre reinforced polymer (CFRP) strips increases the resistance of the main bearing elements by 50% and allows a quick and easy upgrade of the towers to higher voltage and bigger G5-antennas.
