Transformer bushing structure:
Pipe insulation with paper capacitance cores call the shots, wearing rope carrier means and the use of multiple sets of pressure generated by axial compression spring force to achieve the overall connection casing and the main seal. 252KV porcelain casing in connection with the connecting pipe clamping structure also aids the heart to enhance the seal strength of the connection parts, the casing of the oil pillow, the connection sleeve are made of cast aluminum alloy to reduce hysteresis and eddy current loss Reduce heat and temperature rise. Connection with measurements on the sleeve tan, C tap installation and extraction of oil samples taken inside the casing valve to release air at the top of the transformer tank bleed plug.Here,bushing transformer have more Information

A capacitor consists of two conductors separated by a non-conductive region[8] called the dielectric medium though it may be a vacuum or a semiconductor depletion region chemically identical to the conductors. A capacitor is assumed to be self-contained and isolated, with no net electric charge and no influence from any external electric field. The conductors thus hold equal and opposite charges on their facing surfaces,[9] and the dielectric develops an electric field. In SI units, a capacitance of one farad means that one coulomb of charge on each conductor causes a voltage of one volt across the device.[10]
The capacitor is a reasonably general model for electric fields within electric circuits. An ideal capacitor is wholly characterized by a constant capacitance C, defined as the ratio of charge ħQ on each conductor to the voltage V between them:[8]
Sometimes charge build-up affects the capacitor mechanically, causing its capacitance to vary. In this case, capacitance is defined in terms of incremental changes:

Thanks START! I had no idea! I am now much more knowledgeable about capacitors than I ever hoped to be....
Side note to amrad: Sorry about the spam. While I will continue to delete this sort of stuff, I am hard pressed to delete this post - as it is hilarious! We definately have a similar sense of humor!
