What Is Dry Type Transformer

<!-- x-tinymce/html -->
Dry-type transformers rely on air convection for cooling and are generally used for local lighting and electronic circuits. Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminal CNC machinery, equipment, etc. Simply speaking, dry-type transformers refer to transformers whose iron cores and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF).
Dry-type transformers are transformers whose cores and windings are not immersed in an insulating liquid. They are used in general public distribution networks or industrial power grids. They can be divided into the following three categories:
(1) Totally enclosed dry-type transformer: a transformer that is placed in a pressure-free sealed casing and cooled by internal air circulation.
(2) Closed dry-type transformer: a transformer that is placed in a ventilated casing and cooled by external air circulation.
(3) Non-enclosed dry-type transformers: transformers without protective casing, cooled by natural air circulation or forced air circulation.
Dry transformers are suitable for various fields and special purposes, such as special transformers for nuclear power plants, marine, and offshore platforms, steel rolling, etc. All of which have been designed and manufactured in my country. For such dry transformers, as long as relevant technical requirements are put forward, they can be delivered for manufacturing. Factory development, design, and production.
