There are a number of basic characteristics of power transformers, which are as follows:
1.The iron cores of power transformers make them extremely heavy and over sized.
2.Iron core made of high-quality cold-rolled silicon steel sheet, shear burr less than 0.02 mm, full miter seam, no punching, no iron yoke. The core columns are stacked and double H glue is used to make the core three columns and two yokes a tight, flat and compact whole, thereby reducing the no-load loss, no-load current and noise.
3.There can be one or more primary and secondary windings on them.

Potting is the process of filling or submersing a complete transformer using a compound material. Transformers can be bonded, sealed, potted, and coated with this glue.It is liquid before curing, and its viscosity varies with the material, performance and production process. Its use value is realized after the glue has completely cured, and it has many properties such as being waterproof, moisture-proof, dust-proof, insulating, thermal conductive, confidential, anti-corrosion, temperature resistant, and shock resistant.

Which is better for coils in high-frequency transformers: flat copper tape or litz wire?
In conclusion,use the Litz wire or flat copper tape based on the magnetic core size and the current.
