Several single wires or bundles are bunched together. Those single wires do not hold a fixed position inside the strand. Their position relative to one another undergoes a permanent change along the entire length of the bunch.
A multitude of applications in cables and conductors
Crucial advantage: good efficiency
Uniform elongation of single wires
Low tolerances, even in single wires (even outperforming ASTM)
Materials: Cu-ETP1 and Cu-OF1
Bare, tin-plated, nickel-plated or silver-plated
Left-hand lay or right-hand lay
Variation: soft annealed
Single-wire diameter: ranging from Ø 0.05 mm to Ø 0.51 mm
Cross-section: ranging from 0.005 mm2 to 630 mm2
