HIGH QUALITY EN STANDARD LV/HV BUSHING

The transformer bushing is the main insulation device outside the transformer box, and the lead wire of the transformer winding must pass through the insulating sleeve to insulate the lead wire and between the lead wire and the transformer shell, and at the same time play the role of fixing the lead wire. Due to different voltage levels, insulating sleeves are in the form of pure porcelain sleeves, oil-filled sleeves and capacitor sleeves. Pure porcelain bushing is mostly used in 10kV and below transformers, it is in the porcelain sleeve to wear a conductive copper rod, porcelain sleeve for air insulation; oil-filled sleeve is mostly used in 35kV transformer, it is in the porcelain sleeve oil-filled, in the porcelain sleeve to wear a conductive copper rod, copper rod wrapped insulating paper; capacitive bushing is used in 100kV or more high-voltage transformer, by the main insulating capacitor core, the outer insulation upper and lower porcelain parts, connecting sleeve, oil pillow, spring assembly, base, equalizing ball, measuring terminal, terminal, rubber washer, insulating oil, etc。
