In the cable selection there is a large spectrum of RAL colors available extruded, co-extruded over a carbon black foundation HDPE layer, or a double-colored layer.

Teufelberger-Redaelli Open Spiral Strands HDPE (OSSH) are manufactured using helically wound, hot-dip galvanized high-strength steel round wires which are generally spun in opposite directions around a central core. Each individual wire is tested and verified for tensile strength, ductility, elongation at fracture, bending, torsional properties and adhesion of zinc coating in accordance with EN 10264 and EN 12385-10. The external plastic HDPE coating is applied by a continuous extrusion process and is closely monitored under factory-controlled conditions. HDPE thickness is based on the nominal diameter of OSS cables.

Main properties: High axial stiffness, high strength to weight ratio, high fatigue resistance, torque balanced, less required maintenance during the lifetime, UV stability against solar radiation, weathering resistance, available in full spectrum of colors
