Dry Type Transformer Application
Sinotech dry type transformers are inherently fire-safe — no flammable oil means zero fire risk, making them the preferred choice for densely populated areas including shopping malls, office towers, hospitals, schools, and metro stations. The sealed epoxy resin insulation also eliminates moisture absorption concerns and requires no periodic oil testing, reducing lifetime maintenance costs significantly compared to oil-immersed alternatives.
