Description
The Threaded Bushings for voltage of 3kV are supplied assembled with the respective porcelain, NBR gaskets, copper threaded rod, blued steel spin grip nut, zinc-plated brass connector and stainless steel lock washer and nut.
High-voltage bushings are either oil-filled or condenser bushings. Oil-filled bushings have a central conducting rod or tube through which the conductor passes. Around this, a series of insulating barriers are held apart by spacers. The barriers and spacers are enclosed in a skirted porcelain shell that is filled with oil. Condenser bushings are similar except that the central rod is wound with alternating layers of insulation and foil. This results in a path from the conductor to the case consisting of a series of condensers. The layers are designed to provide an approximately equal voltage drop between each condenser. In some condenser bushings, the whole bushing is enclosed in a skirted porcelain shell. Other types have only the exposed part of the bushing enclosed in the porcelain shell.
