Prevention of ice and frost on the overhead tram wires in the winter period October 2022- march 2023.
Odense Letbane P/S was commissioned in May 2022. The Railway consist of 2 x 14.2 km contact wire and a depot arear with contact wire. These overhead contact wire supply 750V direct voltage to the Light Rail section from Tarup Center in the north to Hjallese Station in the south, both in Odense.
Ice on the contact wire/overhead line can cause light rails to loose power, generate damaging arcs, disturbing the modern engine control and destroying both the pantograph and the overhead wire. The ice will in any case cause arcing and lead to excessive wear to the pantograph conductors, and in worst case lead to traffic delays and service disruption.
Odense Letbane needs to make sure that there does not occur disruption due to ice on the contact wires.
As part of the prevention of icy overhead lines during the winter period, Odense Letbane thus wants treatment with a form of spraying/coating of the overhead contact wire system with Interflon lupe EPR, or an alternative product with similar or better properties in preventing ice and frost formation on overhead wire.
The treatment must cover the entire winter season October - March. The client accepts that monthly treatment may take place. with treatment three times in the period October - December 2022, and three times in the period January - March 2023.
The tenderer also gives the contracting authority an option for an additional treatment, should it prove necessary.
