Abstract :
The dielectric spectra of composite materials on the basis of natural and synthetic rubbers filled with a ferroelectric ceramic powder PZT (lead zirconate titanate) were studied in this paper. It was demonstrated that the study of the relaxation dielectric spectra parameters allows the energy of the work of adhesion and the optimal filler content in a matrix to be estimated. The stabilization of dielectric properties of composites is observed at the frequency range 50-500 Hz at the optimal filler content in a matrix. It is very important insofar these composite were used as the additional insulating layer in HV power distribution cables.
