KLK manufactures and markets rigid catenaries for rail facilities around the world, and has in recent years gained considerable experience and obtained results that leave customers fully satisfied.
The rigid catenary system is an alternative rail transport power supply system to the conventional catenary. Its characteristics make it the most widely used system in tunnels, although its lower maintenance costs justify its installation in any case.
It consists basically of an aluminium profile with a clamp-shaped area to hold the copper contact wire. It forms a whole with high mechanical strength and high current flow cross-section.
