Abstract
Abstract Anaerobic resins are cured in a gaseous atmosphere which does not contain oxygen. An insulated conductor is placed in a vacuum and is impregnated with an anaerobic resin under pressure. The conductor is then placed in a non-oxygen containing atmosphere, such as nitrogen, which cures the resin.
