DIN Transformer Bushings

1. Definition: 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 to fix the outgoing lines.

2. Classification: Due to different voltage levels, insulation sleeves come in various forms such as pure ceramic sleeves, oil filled sleeves, and capacitor sleeves.
