Радиационная стойкость кабелей внутренней прокладки общепромышленного применения

Abstract

Influence of radiation on electric capacity and 80 dielectric loss tangent of commercial network unshielded cables of the fifth category is considered. It is revealed that change of capacity does not exceed 10 % up to the radiation doze of 30 Mrad. As for tg6, the radiation resistance criterion increases at the doze higher than 10 Mrad. Commercial cables with polyvinylchloride shielding and without radiation-modified polyethylene insulation can be applied at radiation doses under 10 Mrad. As an attribute of critical cable operation condition, sign inversion of electric capacity can serve.
