The Transformer Bushing Requirements
- Oct 09, 2018 -

The transformer bushing leads the high and low voltage leads inside the transformer to the outside of the fuel tank. It is not only used as a lead-to-ground insulation, but also acts as a fixed lead. The transformer bushing is one of the current-carrying components of the transformer. During the operation of the transformer, the load is long-term. Current, through a short circuit current when a short circuit occurs outside the transformer. Therefore, the following requirements are imposed on the transformer bushing:

(1) Must have specified electrical strength and sufficient mechanical strength.

(2) It must have good thermal stability and can withstand transient overheating during short circuit.

(3) Small size, small quality, good sealing performance, strong versatility and easy maintenance.
