    摘要: A high temperature insulation for liquid-filled transformers. This invention is a composite sheet material composed of a substrate saturated with a thermally stable polymeric resin that provides a micro-porous structure. This structure allows dielectric fluid to saturate the electrical insulation material. The insulation materials have a low moisture absorption, and do not generate water when aged during the life of the transformer. The invention improves transformer life expectancy with a cost effective alternate electrical sheet insulation material. This material has better heat aged electrical properties than cellulose, which is presently the most common insulator for liquid filled transformers.
