Abstract

Dry-band arcing on all-diectric, self-supporting (ADSS) cables can be at times problematic. A novel solution to alleviate the problem is the introduction of conductivity into the cable. Referred to as retro-fit rod solution arc arrest system (ASS), the scheme consists of a rod of controlled resistance per unit length that is attached to a previously installed ADSS cable. The rod covers the first 50 m of the cable adjacent to the tower, and it is grounded at the tower. The rod is held on by simple chips that enable it to be manually pushed on to the cable with no mechanical aids. Extensive trials coupled with computer simulations in the United Kingdom show that the rod works as intended.
