Ceramic insulator
Ceramic insulators manufactured by NOWARUN are produced from alumina ceramic based on aluminium oxide (Al2O3) to provide electrical insulation, mechanical strength, and high temperature resistance. Engineered for thick film integrated circuits and demanding industrial assemblies, each ceramic insulator offers high hardness, wear resistance, and corrosion resistance. Parts are custom fabricated to drawing specifications rather than supplied from a standard catalogue.
