Wire Stranding Charts. – Bunch stranded wire. Wires are twisted without a geometric relationship to each other. – Concentric stranded wire. Each layer of the stranding has all strands in the same direction and position. RB –Rope construction with Bunch stranded groups. Similar to concentric for the groups of strands. Each Bunch Stranded strands.
When you have the option to choose it's important to understand the construction of your cable and how the differences between solid and stranded conductors could affect your application. Solid: Solid conductors consist of just one strand of metal.
European Cable Stranding Chart Guidelines have been established for measuring conductor sizes within the European Cable industry. In the past, conductors were normally measured by either their cross sectional area, number and diameter of individual strands, or both.
Solid & Stranded Specifications • Conforms to ASTM B-1 for hard drawn, ASTM B-2 for medium hard drawn, ASTM B-2 for soft or annealed copper wire and ASTM B-8 for concentric lay. • Conforms to Federal Standard QQ-W-343.

CONDUCTOR STRANDING CHART. Conductors in the past were normally measured by the number and diameter of individual strands, cross sectional area or both. The new system for measuring flexible conductors (column 3 & 4 in table below) now centers on the core resistance and the maximum strand diameter. Cables now can have a smaller diameter and ...
