  • This paper describes thermal-mechanical performance and ultimate mechanical-strength test for the purpose of aging analysis of suspension insulator. The temperature of insulator surface according to the aging of suspension insulator was rised about 2[$^{\circ}C$] to 7~8[$^{\circ}C$] difference comparing with the atmospheric temperature. The autoclave expansion of portland cement at the specimen that had much puncture insulator(autoclave measuring value : 0.37[%]) was higher than those of a little puncture insulator (autoclave measuring value : 0.1[ %] ). Quality standard and mechanical-strength of used suspension insulator deteriorate more remarkably than those of new suspension insulator. It is required that thermal-mechanical performance test standard be revised in the future.
