These cross-bars are used on medium voltage tie plate metal towers for anchoring the line or attaching the branching elements.
The identification of the cross-bars is made using the following nomenclature:
XXD – YYY Z
XX: Indicates the fitting resistance.
YYY: Indicates the fitting length.
Z: Indicates the type of cross-bar, there are three possibilities:
S: Anchoring cross-bar.
SE: Cross-bar for Xs.
R: Cross-bar for sectionalisers.
