Porcelain Transformer bushing / Insulator The transformer bushing is the main insulation device outside the transformer box. The lead wires of the transformer winding must pass through the insulating bushing to insulate the lead wires between the lead wires and the transformer casing. At the same time it play the role of fixing the lead wires. Due to different voltage levels, the insulating bushings are available in pure porcelain bushings, oil-filled bushings and capacitor bushings. Bushing insulator is used between the transformer rectifier and the discharge electrode suspension of an ESP for leading high voltage into the electric filed, functioning as insulating and supporting of the bus rod. By its own structure it is divided into two types: pure ceramic insulator and combined insulator. A combined insulator consists of the ceramic body and metal fittings which are cemented together with binder that can withstand high temperature. The cementing faces on a ceramic insulator body are knurling or sanding treated, and a high temperature withstanding elastic layer is interposed between the ceramic body end and metal fittings, and a buffer is also applied between them to prevent from loosening. No metal fittings for pure ceramic insulator type. The insulator is glazed white or brown on the ceramic part surface, and the metal fittings are applied with anti-rusting paint for the combined insulator type. The ceramic bushing insulator conforms to the Chinese standards of 'Technical specifications for high-voltage insulator' and 'ceramic insulator used in electrostatic precipitator', and the IEC series standard is also followed.
