Transformer bushing is an insulation bushing that leads the high and low voltage leads inside the transformer to the outside of the oil tank. It not only serves as insulation for the leads to the ground, but also serves as a fixed lead. Transformer bushing is one of the current carrying components of the transformer. During transformer operation, it passes through the load current for a long time, and when a short circuit occurs outside the transformer, it passes through the short-circuit current. Therefore, there are the following requirements for transformer bushings:
(1) Must have specified electrical strength and sufficient mechanical strength.
(2) It must have good thermal stability and be able to withstand instantaneous overheating during short circuits.
(3) Small appearance, low quality, good sealing performance, strong universality, and easy maintenance.
