Preparation and Property of Insulated Tension Pole for 550 kV GIS Isolation Switch

Abstract

550kV GIS isolation switch of aramid insulated tension pole was studied in this paper. The aramid fiber fabric and polyester fiber fabric are rolled into the mold in the winding technology. Through the vacuum pressure impregnation process, the epoxy resin, curing agent, accelerator system was filled, the product of the aramid insulated tension pole was obtained after curing and stripping. Meanwhile, the electrical insulation characteristics and mechanical properties of insulated tension rod were performed. The results indicated that the insulated tension pole made in the vacuum impregnation process owned excellent electrical insulation performance and mechanical properties, which was basically able to meet the performance requirements of foreign products.
