Ropes: Ropes

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.
