Dry-band voltage of self-supporting fiber optic cable installed on pylons of medium and high voltage overhead lines

Abstract

Demonopolization in the power and telecommunications sectors is a global process that has its positive and negative repercussions on human life, both from a technical and ecological perspective. One negative aspect is, among others, the difficulty in obtaining new or expanding existing corridors. For this reason, optical cables are increasingly being installed on high-voltage power line poles. These cables are self-supporting structures without metal parts and are located in a strong electric field. This paper analyzes the voltages on dry zones of the contaminated sheath of a self-supporting optical cable without metal parts that is suspended from medium-voltage and high-voltage power line poles. These voltages can damage the optical cable or cause some other undesirable consequences.
