Daelim Transformer Certificate

The 5MVA power transformer employs vegetable oil as the insulating liquid and utilizes the KNAN cooling method. This insulating liquid not only enhances the transformer's insulation performance but also prolongs its operational lifespan. Importantly, it poses no environmental pollution risk and offers high fire protection levels. A lightning arrester is incorporated on the high-voltage side. Transformer gauges include contacts, a low oil level alarm, high oil level trip, high oil temperature alarm and trip, and an automatic pressure release device.
