Evaluation of several polymer films for use as electrical insulators


A facility was developed in which polymer samples were aged to 32,700 h with an applied load of 6.9 MPa and at temperatures of 70, 110, 135, and 160&#x00B0;C. The aging environment was 0.4 MPa (4 atm) SF<inf>6</inf> containing either 4 or 40 Pa (40 or 400 &#x00B5;atm) H<inf>2</inf>O. The polymers evaluated to 32,700 h were polyethylene terephthalate… (More)
