1.Classification

Due to different voltage levels, insulation sleeves come in various forms such as pure ceramic sleeves, oil filled sleeves, and capacitor sleeves. Pure porcelain bushing is commonly used in transformers with a voltage of 10kV and below. It involves threading a conductive copper rod through the porcelain bushing, which is insulated with air inside; Oil filled bushing is commonly used in 35kV level transformers. It is filled with oil in a porcelain bushing, with a conductive copper rod inserted inside the porcelain bushing and insulated paper wrapped around the copper rod; condenser bushing is used on high-voltage transformers above 100kV, consisting of a main insulated capacitor core, upper and lower porcelain parts with external insulation, connecting sleeve, oil conservator, spring assembly, base, equalizing ball, measuring terminal, wiring terminal, rubber gasket, insulating oil, etc.
