THE EFFECTS OF RADIATION ON SILICONE RUBBER WIRE AND CABLE INSULATION

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.
