Abstract
The present disclosure describes an assembly adapted for mitigating dry band arcing on power distribution line insulators. The assembly includes a polymeric insulator for power distribution line having a core, two end fittings affixed to opposing ends of the core, and a housing circumferentially surrounding the core. The housing including an upper end section and a lower end section each overlapping a respective end fitting, and a series of axially spaced apart annular sheds projecting radially outwardly from an outer surface of the housing. The device further includes a cover having a main body including a sidewall and a top wall, the sidewall and the top wall together define a cavity. A lower edge of the sidewall defines a lower opening and the top wall includes an upper opening, both the lower and upper openings being in communication with the cavity. At least a portion of the upper end section of the housing is received through the upper opening of the cover and one or more of the annular sheds are received within the cavity of the cover. Methods of mitigating dry band arcing on power distribution line insulators are also described.
