Research on Adhesive Joints of Low-temperature composite Axial Insulation Break

Abstract

Abstract. Threaded adhesive joints between stainless steel electrodes and insulating structure of axial insulation break was studied in detail. Wet winding process was chosen for Glass Fiber Reinforced Plastic inner insulation tube, and threaded adhesive method was chosen for joints bonding GRP to Stainless Steel. DC High voltage test showed that it is fairly good results to eliminate the interface crack in low temperature heat shrinkage and mechanical stress to meet 56kV insulation requirements for superconducting magnetic systems.
