Coating electrical wire

copperaluminumcopper alloy

High-flexible round strands and ropes. Apart from their extraordinary flexibility, these product types are characterized by an extremely long flex life. Applications • Earthing straps • Connectors • Conductors for low-voltage lighting • Welding Particular benefits for our customers • Uniform elongation of single wires • Low tolerances, even in single wires (even outperforming ASTM) Manufacturing range • Materials: Cu-ETP1 and Cu-OF1 • Aluminium and LEONI Histral® alloys upon request • Coating: bare, tin-plated, nickel-plated and silver-plated • Left-hand lay or right-hand lay • Variations: hard or soft annealed • Single-wire diameter: ranging from Ø 0.05 mm to Ø 0.51 mm • Cross-section: ranging from 0.02 mm2 to 630 mm2 (bigger cross-sections upon request) Table of current loads Below you can select your appropriate cross-section as a function of the current load (determined at a room temperature of 35 °C and the maximum temperature of the conductor, viz. 70 °C). Due to other factors usually playing a role as well, the values indicated below are to be seen as a non-binding recommendation. Lay length for bunches: 25 to 50 times the diameter of the strand.
