Non-condenser porcelain bushings
A simple non-condenser bushing for low- and medium-voltage applications may be a rod of conducting material inserted into a porcelain tube. This has a central current-carrying bolt, usually of copper, and a combination of the porcelain shell and the transformer oil provides the insulation.
Hitachi Energy offers a comprehensive portfolio of porcelain bushings for low- and medium-voltage applications, including insulator connecting flags.
