Thermal-Oxidative Aging Effects on the Dielectric Properties of Nuclear Cable Insulation

Thermal-Oxidative Aging Effects on the Dielectric Properties of Nuclear Cable Insulation

In order to satisfy demands of cable insulation for nuclear power, a low-smoke, halogen-free flame retardant and better cryogenic property insulation was prepared. The effect of thermal-oxidative aging on the dielectric properties was researched in this paper. The changes of chemical structure and t...
