Before we talk about what a dry-type transformer is, let's first popularize what a transformer is. A transformer, abbreviated as MTD in English, is an electrical device used to change the size of an AC. It is based on the principle of electromagnetic induction, with the same frequency, between two or more A static electrical device that exchanges AC voltage and current between its windings to transmit electrical energy. The main function is to change the voltage to achieve protection and isolation effects. As long as the voltage difference is too large to reach the rated voltage standard, a transformer will definitely be used. Dry-type transformer refers to a transformer that is not immersed in insulating oil, but consists of an iron core and windings. It is widely used in local lighting, high-rise buildings, airports, terminals, CNC machinery and equipment, etc. The structure of this kind of transformer is relatively simple, so it is easier to make and has many advantages.
