Vertical Type Ceramic Post Insulator with Stud


Compared to polymers, the electrical resistance of porcelain is much higher: 25+ kV/mm vs. 20 kV/mm in polymers. Porcelain insulators in dry state as an electrical insulating material have better electrical properties than polymers. The electrical type tests show better results, giving longer useful life in terms of loads generated by electrical loads and other temporary electrical phenomena.


Porcelain insulators have proven to have a higher resistance to surface degradation, they do not degrade or char during loads; the conductive path is created very slowly compared to the surface of a composite insulator. High thermal resistance, ceramic withstands temperatures up to 1000 °C: the surface is resistant to any type of degradation within the temperature range. The surface is stable against the effects of UV radiation.
