📦 Product Description
High Voltage Transformer
Oil Immersed Series Transformer

The fully sealed oil-immersed power transformer offers low loss, low noise, and high efficiency, ensuring energy-saving benefits and reduced pollution. Unlike standard oil-immersed transformers, it eliminates the oil conservator, using a corrugated tank's elasticity to adjust oil volume automatically. This design isolates the transformer from air, preventing oil and insulation degradation, enhancing reliability, and minimizing maintenance needs.
