Transformer hollow bushing insulator is used to take the high voltage and low voltage down-lead within the transformer out of the oil tank. It is not only the insulation to the earth for the down-lead but also a supporting and fixing part. Therefore, the transformer hollow insulator / ceramic hollow insulator must meet the electrical and mechnical strength shown in the manufacturing standard.
Middle voltage transformer can use ceramic/porcelain bushing insulator; high voltage transformer normally uses oil immersed porcelain bushing and capacitive ceramic hollow insulator.
Transformer hollow bushing insulator has various of shape:
ANSI thread ceramic hollow insulator
