Abstract :
The all-dielectric self-supporting (ADSS) cable offers many advantages when installing an optical fiber network on high-voltage overhead lines. Generally, the use of ADSS cables is confined to system voltage levels well below 275 kV because of the threat of dry-band arcing on the cable sheath. This limit is somewhat arbitrary since, in polluted conditions, cables can fail at much lower system voltages, and in some higher voltage installations no problems have been witnessed. A solution to the problem of dry-band arcing on ADSS cables has been proposed previously, where 50-m resistive rods are attached to the self-supporting cable after installation. The first large-scale installation of this system has been successful, and the first six years of operation is reviewed. The installation is in a particularly aggressive situation and a high level of maintenance has been found to be necessary
