Abstract :
This document* combines the experience and expertise of electric power utilities, manufacturers, and research laboratories into a single report that provides minimum test requirements for non-ceramic transmission insulators. The requirements are divided into material tests and insulator design tests that are needed to assess the relative merits of a variety of possible materials and insulator designs. The paper is intended for use by electric power utility engineers and insulator manufacturers to establish minimum material and design specifications for non-ceramic insulators. Insulators failing to meet the minimum test requirements should not be considered for long term use because of unsatisfactory materials, design, or both.
