Description

Technical Field

[0002] Epoxy-cast dry-type transformers are a type of dry-type transformer formed by casting epoxy resin under vacuum and then curing it. They have advantages such as high insulation strength, strong short-circuit resistance, and moisture and dust resistance. Epoxy-cast dry-type transformers can operate reliably in harsh environments. In addition, they have the advantages of low loss, low noise, small size, and light weight. Epoxy-cast dry-type transformers usually use water cooling for heat dissipation.

Epoxy-cast dry-type transformers are generally located in remote areas, making maintenance more difficult.
