The analysis of temperature and frequency dependences of electrical parameters of multilayer polymer insulation materials
In this paper, the temperature and frequency dependences of electrical conductivity, dielectric constant, loss factor for multilayer polymer insulation materials PA-PET-PA and TF-PET-TF are obtained. The influence of relaxation processes and temperature transitions in the studied materials on the change of these parameters is determined. It is shown that in the case of the studied materials, the electrical parameters of the multilayer material are determined primarily by the structure and properties of the adhesive.
