Abstract:

Three silicone dielectric fluids - Dow Corning QF l-0l58, General Electric SF 8520, and General Electric SF 9720 - were irradiated while their electrical properties were being measured. There were samples of each fluid at temperatures of 40 F, 200 F, and 400 F. A mixed neutron-gamma radiation field was provided by the Ground Test Reactor. The samples were subjected to a maximum gamma dose of 2.5 x 10 to the tenth power ergsgm C and a maximum integrated neutron flux of 1.7 x 10 to the fifteenth power ncm2. Extensive preirradiation measurements were made of the dielectric constant, dissipation factor, resistivity, and dielectric strength of each fluid. These measurements were used as a standard to which the irradiation and the postirradiation measurements were compared. Author
