Limiting electrical degradation of all-dielectric self supporting cables

摘要

An assembly for use adjacent an earthed suspension region 20 of an all-dielectric self-supporting cable 10 suspended in an electric field at the earthed suspension region from a tower or the like for limiting dry band arcing adjacent the earthed suspension region is disclosed. The assembly includes an electrically conductive device 21 clamped to the cable remote from the earthed suspension region 20 and structure defining a current path having an arc gap connected between the device 21 and the earthed region 20.
