Last July, French tramway operator STAS in Saint-Etienne decided to install for the first time the VALTHERMO contact wire manufactured by NKT on a 4 kilometers extension of the network.
This Copper new alloy will bring benefits to STAS by improving the permanent temperature from 80°C to 100°C with a conductivity >97% IACS. Thanks to VALTHERMO also you will extend the life cycle because of lowest wear and creep compared to existing copper alloys available.
In conclusion VALTHERMO is already a proven technical solution with comparable advantages to Copper-Silver without the effect of Silver price fluctuation.
Today, several French tramway operators already make decision for VALTHERMO like in Strasbourg, Grenoble, Lyon and Saint-Etienne.
