Self-priming silicone elastomeric coatings for high voltage insulator bodies

摘要

In electric power transmission, there is a trend towards higher operating voltages and more severe service conditions for outdoor insulators. Historically, higher voltages have called for bigger, heavier insulators, with larger support structures to carry the increased weight. Now, for economic reasons, there is an urgent need to reduce weight and size in insulators and support structures. Considerable research and development effort is being spent to synthesize and evaluate stronger, lighter-weight insulating materials.
