The factors influencing on occurrence of the radial imperfections of electric insulation of power high-voltage coaxial cables are analyzed. On the basis of a differential equivalent circuit of non-uniform electric insulation the analysis and calculation of distribution of a resulting radial strength of electric field in insulation with different level of its imperfections are carried out. The quality assessment criterion such insulation with definition of its critical value is offered. References 6, figures 3.
Key words: solid electric insulation, radial electric field, polarization efficiency.
