Saya mau tau Terminal dari Trafo. Jelaskan dalam bahasa sunda

Very small transformers will have wire léads connected directly to the ends of the coils, and brought out to the base of the unit for circuit connections. Larger transformers may have héavy bolted terminals, bus bars or high-voltage insulated bushings made of polymers or porcelain.  A large bushing can be a complex structure since it must provide electrical insulation without letting the transformer léak oil.
