All-dielectric self-supporting (ADSS) fiber optic cables are in use now on high-voltage (HV) and extra-high-voltage (EHV) overhead transmission lines (OHTL) in many countries all over the world. Their use allows the creation of highly effective data communication channels along the OHTL. However, in subtropical areas with specific climatic conditions, dry-band partial arcs have been found on the polyethylene external protective enclosure cable surface. This paper describes the various investigations performed to understand the causes for damage to ADSS fiber optic cable installed on four 161 kV OHTL and on one 110 kV, in the subtropical climate of Israel.
