Ceramic Insulators grade Calcined Bauxite
Electrical procelain insulator has high requirements about the mechanical properties, electrical properties, environmental
performance (cold and hot, squalidity, aging resistance, etc.). Using calcined bauxite as the material could meet this requirement
perfectly. Procelain insulator bauxite has good intensity and its long-term performance could also reduce the manufacturing cost. It
also has well insulativity and mechanical strength, both its rigidity and heat stability are higher than others, its hot and cold impact
performance is also superior.
Application of porcelain insulator calcined bauxite:
Most high voltage insulators producers choose calcined bauxite powder as necessary raw materials for manufacturing
electrical porcelain insulators used for electric line, power station, protector and switches etc. The porcelain insulator that burns by
high-temperature firing from the bauxite, kaolin, feldspar and other natural minerals is widely applied to electric power industry
system. To produce the porcelain, calcined bauxite is used instead of alumina. The simultaneous addition of clay and kaolin, in
each case containing more than 5% by weight of foreign metal oxide inclusions, results in a porcelain which, compared to an
alumina porcelain of the same mechanical strength, can be produced at significantly lower cost. The porcelain is suitable in
particular for applications for highly mechanically loaded components used in electrical insulation.
