POLYMER INSULATOR AND ITS MANUFACTURE

Title:

POLYMER INSULATOR AND ITS MANUFACTURE

Document Type and Number:

Japanese Patent JPH11329124

Kind Code:

A

Abstract:

To heighten water-repellency and lengthen the life span, compared with a polymer insulator with a conventional silicone rubber envelope.

This polymer insulator 1 is composed of a core member 2, and an envelope 3 consisting of a barrel part 4 and plural umbrellas 5 around the core member 2. Here, a water-repellent layer 11 having ultra-fine irregularities on the surface is provided on the envelope 3. This water-repellent layer 11 is formed by applying a mixture of silicone rubber and resin particulates on the envelope 3 of the polymer insulator 1, or by press molding or casting the mixture. Or else, the water-repellent layer 11 is formed by applying the silicone rubber on the envelope 3, and by dusting the resin particulates evenly over the applied part before silicon rubber is cured, to secure them fast.
