Padova
Between art and transportation
Year: 2023
Country Italia
Partners we worked with: Salcef
Line: SIR 3, Padova
Electrified kms: 5,4km double track
Curiosity:The Padua SIR 3 line has the following features: 750 V direct current, 1 contact wire. We have supplied inverted cantilever aluminium suspensions with silicone-coated insulators type L3704L2050-OF + Leonardo mast.
The end customer paid particular attention to the aesthetic details of the line.
REM Canada
A heavy light rail project
Year: 2019
Country: Canada
Partners we worked with: CACEF - INEO SCLE - NOUVLR
Line: Réseau Express Métropolitaine
Electrified kms: 67 km
Curiosity: Gruppo Bonomi supplied over 3,800 cantilevers, more than 84,000 droppers and a total of approximately 9,000 electrical connections.
The Canadian regulations chosen by the end customer also required the overhead contact line to be tested according to the high-voltage line standard. This regulation took into account the fact that in 1998 the 'North American Ice Storm' hit Canada, a storm that destroyed part of the power distribution network. Subsequently, the regulations became more stringent, resulting in more onerous and careful design and reinforced overhead contact line suspension geometries.
