Modification of the composition and technology of the ceramic - polymeric insulators processing.

The nano-sized filler influence on the physical-chemical and electrical properties of the composite CP (ceramic-polymeric) material to be applied in outdoor line HV insulators has been determined. Also the results of the electrical and mechanical examinations of the CP insulators moulded with the use of the dies made of PET have been given in the work. As a standard, the moulds for flask - moulding are made of PP material what, because of PP high adhesion, causes some difficulties during forming of insulator and leads to deteriorating the quality of the insulator surface.
