ABSTRACT:
An improved high dielectric strength unitary insulation sleeving is described. The insulation sleeving comprises an inner insulating layer such as woven fiberglass overcoated with an insulation resin such as an acrylic resin, having an additional insulating layer such as fiberglass overbraided upon it. The overbraided layer is secured to the inner resin-sleeving member by means of an additional impregnation with an electrically insulating binder resin, such as acrylic, to secure the composite together. This material, in addition to having the requisite mechanical and electrical properties for use on coil leads, is specifically adapted to VPI processing and can be utilized reliably with minimal effort. For example, the material has comparable and, in some instances, superior dielectric breakdown voltages as compared to conventionally used sleeving and is not subject to layer slippage which can decrease electrical properties, as can occur with conventionally used materials.
