Abstract
The present invention discloses a glass covered electrical insulation having an inner lining of glass fibers coated with a flexible, high temperature, electrically insulating silicon polymer, the electrically insulating layer then has a second layer of glass fibers overbraided on it and bonded to it by the use of a heat treating process. A further teaching is the method of making the flexible sleeving and a method of use. The sleeving is particularly adapted for use in VPI processing and has superior flexibility as well as higher temperature capabilities than sleeving of the prior art.
Claims4
A unitary, flexible, electrically insulating sleeving consisting essentially of a braided tubular inner layer of electrically insulating yarns, overcoated with a high temperature, electrically insulating flexible silicone polymer which is cured and an outer layer of electrically insulating yarn overbraided and head bonded to the cared insulating polymer resulting in a unitary insulating sleeving having high dielectric strength and improved flexibility.
