📦 Product Description
Dry type transformers use air cooling, and the windings are directly exposed to the air without the need for insulation oil. It has a compact structure, easy maintenance, excellent fire and moisture resistance, and can be installed in densely populated places such as indoors. Using epoxy resin casting or H-grade insulation materials, it is resistant to high temperatures and has a long insulation life.
