However, there are some important issues with the same
SCS in zones with highly polluted conditions. SCS installed in
coastal areas, where an increase in the reliability of the lines was
required, were not successful. Distribution lines with SCS in
the coast of the same province had problems during the second
coastal storm after their installation [4]. Tracking and erosion on
the surface of spacers and covered conductors damaged these
components in a similar form as reported in a previous publication
[5] and shown in Figure 4. Some hooks broke apart from the
spacer, and as a result the conductors dropped.
