Next generation of hinge mounted insulating crossarms

Within the framework of expanding Belgium’s 380 kV backbone network, Elia has implemented multiple projects using lattice towers equipped with insulating cross-arms, which have been in service since 2015. This choice is driven by the aim to limit the visual impact of these new lines as much as possible, since public acceptance is the biggest challenge when building new lines in Belgium. The current design complies with the design specifications set out in applicable IEEE guidelines [3, 5]. Pivoting insulated cross-arms
