Modification of the composition and technology of the processing of ceramic-polymer insulators

The nanosized filler influence on the physicochemical and electrical properties of the composite ceramic- polymer (CP) material to be applied in outdoor line HV insulators has been investigated. 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 presented. As a standard, the moulds for flask - moulding are made of PP material what, because of its high adhesion causes some difficulties during forming of insulator and leads to deteriorating the quality of the insulator surface.
