Oil immersed 3-phase Pad Mounted Transformer
Oil immersed 3-phase Pad Mounted Transformer are typically housed in weatherproof enclosures made of durable materials such as steel or aluminum. They are designed to withstand harsh environmental conditions including rain, snow, and extreme temperatures. The enclosure also provides safety by isolating the electrical components.
