The insulators feature high electric dielectric quality, fused with a good mechanical quality, makes aluminum oxide the material premise for a huge number of insulators and uncommon parts considerably under high temperatures. The superior material used is AK97M, created by Barat Ceramics, with a dielectric quality greater than 30kV/mm, meets the high demands set by the plant makers and considers ideal configuration results. Lastly, it is close to measurement tolerances and the measurement is up to 500 mm.
