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
The construction of a bunch is derived from the cross-section required, which leads to the electrical conductor featuring a certain resistance level. Different cross-sections with the same resistance value can be generated by applying single wires of varying sizes.
Reel sizes from 80 mm (1 kg) to 630 mm (400 kg), subject to diameter
