ELECTRICAL TREE SUPPRESSION IN HIGH-VOLTAGE POLYMERIC INSULATION

TITLE ELECTRICAL TREE SUPPRESSION IN HIGH-VOLTAGE POLYMERIC INSULATION INVENTORS SOLI S. BAMJI ALEKSANDER T. BULINSKI JOHN DENSLEY Polymeric dielectrics which are exposed to highly divergent electric fields break down more quickly than expected because of the generation of ultra-violet radiation at defect points which degrades the polymer locally and leads to the formation of electrical trees in a polymeric insulation. The use of ultra-violet stabilizers, preferably in combination with reduced concentration of oxygen in the polymer, significantly extends the time to initiation of electrical treeing by preventing photodegradation of the polymer.

This application is a continuation-in-part of U.S. application Ser. No. 13/751,835, filed Jan. 28, 2013.This disclosure relates to a route to non-phthalate, aromatic ester plasticizers.Plasticizers are incorporated into a resin (usually a plastic or elastomer) to increase the flexibility, workability, or distensibility of the resin. The largest use of plasticizers is in the production of “plasticized” or flexible polyvinyl chloride (PVC) products. Typical uses of plasticized PVC include films, sheets, tubing, coated fabrics, wire and cable insulation and jacketing, toys, flooring materials such as vinyl sheet flooring or vinyl floor tiles, adhesives, sealants, inks, and medical products such as blood bags and tubing, and the like.Other polymer systems that use small amounts of plasticizers include polyvinyl butyral, acrylic polymers, nylon, polyolefins, polyurethanes, and certain fluoroplastics. Plasticizers can also be used with rubber (although often these materials fall under the definition of extenders for rubber rather than plasticizers). A listing of the major plasticizers and their compatibilities with different polymer systems is provided in “Plasticizers,” A. D. Godwin, in Applied Polymer Science 21st Century, edited by C. D. Craver and C. E. Carraher, Elsevier (2000); pp. 157-175.Plasticizers can be characterized on the basis of ...
