Polysil poised for the marketplace

Polysil, a polymer concrete developed by the Electric Power Research Institute (EPRI) as an electrical insulator, has found both a good application and a commercial market after three years of field tests. Polysil's advantages over conventional insulator materials derive from its excellent mechanical and dielectric strengths, and the fact that it is nontracking (i.e., its surface will not carbonize even under severe arcing). It polymerizes without heat, and can be cast into detailed shapes. Its processing allows the encapsulation of such metal components as voltage grading end caps, resisitors, and capacitors. Because it is a structural material, Polysil may eliminate the need for separate insultors in substations. EPRI has licensed nine manufacturers. A directory of Polysil insulator manufacturers and licensees accompanies the article.
