Continuous use at 150°C is UL rated for polysulfone and 180°C is reasonable for polyphenyl-sulfone. Data is presented to show the effects of time and temperature upon the dielectric strength, dielectric loss, and mechanical properties of these polyarylsulf ones. The frequency and temperature dispersions of dielectric properties are presented. The high oxidation state of the normal polymer is suggested as an explanation of very great resistance to failure by electrical treeing and for the good flammability ratings.","PeriodicalId":214025,"journal":{"name":"1977 EIC 13th Electrical/Electronics Insulation Conference","volume":"230 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1977-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124537175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In view of the high interrupting and continuous current ratings involved, selected insulating materials were tested in 135°C and 500 psig arced SF6 gas environments. The finally selected materials showed no measurable leakage current during a 300 hour exposure test and they all withstood a surface voltage stress in excess of 85 kV/inch. These tests, therefore, demonstrated that SF6 is a viable insulating medium for even higher temperature and pressure, permitting higher performance and lower costs in future switchgear applications.","PeriodicalId":214025,"journal":{"name":"1977 EIC 13th Electrical/Electronics Insulation Conference","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1977-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116299894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
