An improved cover for protecting insulators used with high voltage transmission lines from contamination. The cover is generally bell shaped and has a lower end fitted over the insulator assembly; when in position, the cover is coaxial with the insulator assembly, and the coaxial relationship is maintained by means of ribs formed on the inner wall of the cover which engage the outer edge of the insulator assembly. The lower end of the cover is dimensioned so that there is adequate clearance between the cover and the lower portion of the insulator assembly, to prevent current for arcing over to the outer surface of the cover.
