ewz Binz substation: earthquake upgrade
We were able to examine the Binz substation, a central structure for the power supply of Zurich-Wiedikon, Albisrieden and Enge dating from 1953, in detail for its seismic-resistant properties and plan measures to strengthen this vital structure.
Are you looking for an experienced partner? We will be happy to advise you.
As a class BWK III structure, the substation must remain fully functional even after an earthquake. On behalf of Elektrizitätswerke Zürich ewz, we carried out a detailed review of the seismic design of the structure and the components of the outdoor plant. Based on these investigations, we developed measures to increase the earthquake-resistant design. These included steel trusses to reinforce the horizontal bracing and special supports for components at risk of tilting, such as masonry walls.
