- Extrusion: thin-gauge coating with high-grade isolation materials
- 7-end strands are particularly suited for data cables with high frequencies of transmission
Particular benefits for our customers
- Uniform elongation of single wires
- Low tolerances, even in single wires (even outperforming ASTM)
The following strand constructions are possible:
7 ends = 1 + 6
19 ends = 1 + 6 + 12
37 ends = 1 + 6 + 12 + 18
More relevant details can be found in ASTM regulation B 354.
7-end and 19-end strands are the preferred choices for cables used in electronics. The precise positioning of the individual wires makes for a smooth and even surface as well as an unvarying diameter.
Strands with the same lay direction are generally called unilay.
Strand with opposing lay direction (SZ stranding) are called true concentric.
The roundness of a strand is driven by its lay length as well:
longer lay length = hexagonal
shorter lay length = more round
Moreover, there is a patented manufacturing process that allows for the production of strands featuring a highly compact and precise round structure: LEONI’s smooth bunches
Reel sizes from 80 mm (1 kg) to 630 mm (400 kg), subject to diameter
