Abstract:

Conclusions Dielectric properties of silicone rubber insulation are not permanently affected to a significant degree by gamma irradiation Dielectric losses during irradiation are no higher than before or after the exposure Physical properties of silicone rubber wire and cable insulation are damaged by irradiation Irradiation at 200C has the same general effects as irradiation at 25C except that the rate of damage is accelerated 4 to 10 times Differences in radiation resistance between silicone rubber stocks is greater when irradiated at 200C than at 25C Since wire and cable insulation must perform both electrically and physically, the effects of radiation on physical properties limit the life For those applications where a life greater than 5 megarads is necessary, all of the generalized information necessary to predict insulation performance is not yet available.
