Product description:
The contact wire support is used for suspension and stabilization of contact wires in tunnels and other restricted installation environments. The design ensures reliable operation and long service life even under high loads.
The basic frame is manufactured from hot-dip galvanized steel while the clip holder is made from CuZn16Si4 and stainless steel. An integrated rubber torsion absorber helps reduce vibrations and improves operational stability.
