Figure 5.10.6 – Some examples of different powerline cross arms configuration. Although there are exceptions, generally sitting insulators (A-B) are not recommended since they pose a high risk of flying fauna electrocution; while hanging insulators (E-F) represent the lower risk of electrocution. Insulators with jumpers represent a medium risk (C-D). Also, horizontal configuration (E) poses the lowest risk, increasing with the complexity of the crossarm (Source: Adapted from Martín et al., 2022).
