Transformer

1. What is a power transformer?

A transformer is an electrical device used to adjust the voltage input and output during power transmission and distribution.

2. Classification of power transformers:

(1) Classification by voltage level:

Main transformer

Distribution transformer

(2) Classification by body assembly process:

Oil-immersed transformer and dry-type transformer

(3) Classification by core material and stacking process:

Stacked core transformer, three-dimensional wound core transformer, amorphous alloy transformer
