WALL-THROUGH BUSHING
The wall-through bushing is used for support and isolates the place where the corona electrets bus bar gets through the ESP shell. There¡¯re two types of them according to the structure: assembled bushing and bare porcelain body.
The assembled wall-through bushing 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.
