The post support insulator is used for supporting hanged frame of discharge electrodes and also for high-voltage insulation.

The post support insulator consists of porcelain body and metal accessories. These two parts are combined by Portland cementing or the thermal-resisting gluing. Elastic pad and buffer layer are used between the porcelain body and metal accessory to prevent loosening. It helps to guarantee the mechanical strengths.
