The transformer bushing is the main insulation device outside the transformer box. The outgoing lines of the transformer winding must pass through the insulation bushing to insulate between the outgoing lines and between the outgoing lines and the transformer shell, while also serving as a fixed outgoing line. Due to different voltage levels, insulation sleeves come in the forms of pure porcelain sleeves, oil filled sleeves, and capacitor sleeves. Pure porcelain bushings are commonly used in transformers of 10kV and below. They are made by threading a conductive copper rod through the porcelain bushing, which is air insulated inside; Oil filled bushing is commonly used in 35kV level transformers. It is filled with oil in a porcelain bushing, where a conductive copper rod is threaded inside the bushing, and the copper rod is wrapped with insulating paper; Capacitive bushings are used on high-voltage transformers above 100kV, consisting of a main insulated capacitor core, external insulation upper and lower porcelain parts, connecting sleeves, oil conservators, spring assemblies, bases, equalizing balls, measuring terminals, wiring terminals, rubber washers, insulating oil, etc.
