ABSTRACT:
An elongated electrical insulator has a supporting rod and barriers or screens spaced along the rod; an intermediate layer of material between the rod and the barriers or screens serves to exclude atmospheric moisture and other materials enhancing the electrical insulating characteristics of the insulator. The rod comprises a non-saponifiable resin reinforced with fiber glass of low alkali content. The barriers or screens comprise a non-saponifiable moisture-repellent polymer containing a filler. The intermediate layer comprises a moisture-repellent non-saponifiable polymer.
