Abstract

A plastic flexible h.v insulator for overhead lines is resistant to electrical erosion. The core of the insulator is fitted with an insulator screen. There is also a plastic layer between the screen and the core of the insulator. It is therefore resistant to polluted and moist environments. The insulator core (10) is embedded in the plastic layer (12) which forms an integrated unit with a plastic screen. The dia. of the screen varies alternately between a smaller (16) and a larger (14) screen. The screens are at right angles to the axis of the insulator. The thickness of the plastic layer surrounding the core is at least 2 mm.
