Figure 39.
The image displays a circular diagram featuring a central blank area surrounded by a series of triangular patterns. The outer edge of the circle is lined with labels representing various codes, ranging from R 001 to R 024, including associated variants (e.g., R 001 A, R 002 A). The triangular shapes surrounding the inner circle create a distinct jagged perimeter. Overall, the diagram emphasizes a radial layout, structured for clarity and organisation of the labeled elements around the central space.Inner ring and the outermost ring of the secondary cables
