The function of the transformer bushing of Dali power equipment is to bow the internal high and bottom pressure leads of the transformer to the outside of the automobile fuel tank. one of the components. In the operation of the transformer, the long-term is based on the amount of load current, and when a short circuit occurs outside the transformer, it is based on the amount of short-circuit current.

Therefore, the following provisions are made for the transformer bushing:

(1) Must have the required compressive strength and sufficient impact toughness of electrical equipment.

(2) It must have excellent heat resistance and be able to withstand a momentary over-temperature during a short circuit.

(3) Small appearance design, small quality, good sealing performance, strong practicability and conducive to maintenance
