Abstract

The pure PTFE nozzles may not be used in the GCB with very high interrupting capacity because of their excessive ablation and carbonization. But it is known that the nozzles with filler can show good performances at the extremely high inetrrupting currents of 50kA or 63kA. So, the manufacturing process of filled Teflon has been carefully studied. Then several specimens have been prepared for the experiments and analyses of their mechanical and electrical characteristics. Finally the high power arc tests have been conducted to the Teflon nozzle with filler of $Al_2O_3$. The results of experiments and tests show that the filled Teflon nozzle has superior mechanical characteristics, comparable electrical characteristics to a pure Teflon nozzle and a distinguished endurance against high power arcs.
