Copper products: Semi-concentric strands

Definition

In semi-concentric strands, the individual wires are subject to an exact positioning, yet without an additional core wire, which ensures an all-out uniform structure.


Applications

  • Extrusion: thin-gauge coating with high-grade isolation materials

Particular benefits for our customers

  • Uniform elongation of single wires
  • Low tolerances, even in single wires (even outperforming ASTM)

Manufacturing range


Construction

The following strand constructions are possible, which depend upon the number of core wires:

10-wire semi-concentric conductor
24-wire semi-concentric conductor

2 core wires:
2 + (2 + 6) = 10 ends
2 + (2 + 6) + (2 + 6 + 6) = 24 ends …
2 + ∑n (2 + n * 6)

14-wire semi-concentric conductor
30-wire semi-concentric conductor

4 core wires:
4 + (4 + 6) = 14 ends
4 + (4 + 6) + (4 + 6 + 6) = 30 ends …
4 + ∑n (4 + n * 6)

12-wire semi-concentric conductor
27-wire semi-concentric conductor

3 core wires:
3 + (3 + 6) = 12 ends
3 + (3 + 6) + (3 + 6 + 6) = 27 ends …
3 + ∑n (3 + n * 6)

16-wire semi-concentric conductor
33-wire semi-concentric conductor

5 core wires:
5 + (5 + 6) = 16 ends
5 + (5 + 6) + (5 + 6 + 6) = 33 ends …
5 + ∑n (5 + n * 6)


Packaging
