Design and Analysis on Electric Performance of Threaded adhesive joints of 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 analysis showed the field strength of the axial break along the interface inner pipe is 1.23kV/mm, and the maximal field strength of the IBs locates on the top end of SS316L electrodes, the value of the maximum field strength is equal to 2.8kV/mm.
