Superior product features
The name of the latest overhead traction line innovation is VALCOND®. Superior product characteristics which meet all the requirements of EN 50149 for CuMg0,2 and CuMg0,5 contact wires, provide increased economy. By optimising the entire process chain the nkt cables engineers have succeeded in achieving considerably increased conductivity - combined with notice­ably lower thermal loss and the corres­ponding major savings on energy.
Pioneering services for rail transport
Since the electrification of rail net­works began nkt cables has been one of the pacemakers in rail traction tech­nology. Constant innovation and the optimisation of a comprehensive range of conductive materials, traction wires and overhead lines guarantee safety, economy and competitiveness on all stretches of rail. Rail operators throughout the world rely on this efficiency and quality. Today and tomorrow.
material properties
CuMg is the contact wire material with the lowest rate of wear and tear and the highest half-hard point of any material in present-day use. Together with its energy-saving potential this means that VALCOND® is technically and economically the ideal solution for equipping new stretches of rail and the refitting of existing installations.
