Description

Technical field [0001] The invention relates to a cable insulating material, in particular to a cable insulating material for nuclear power plants. Background technique [0002] Cables used in nuclear power plants require cable insulation materials to have excellent electrical properties, strong radiation resistance, excellent heat aging resistance, excellent humidity and heat resistance, halogen-free, low smoke, low toxicity, good flame retardancy, and long service life. At present, commonly used insulating materials are polyethylene, cross-linked polyolefin and ethylene-propylene rubber. The polymers in the above-mentioned general materials will produce ionization or excitation reactions under the action of irradiation, and the following chemical reactions will further occur: macromolecules are formed by radiation Irradiation-induced cross-linking reactions, irradiation-induced degradation reactions, oxidation reactions, gas products, and others such as isomerization. The...
