Type And Meaning
Product Features
Three radiator types available
This three-phase oil-immersed transformer offers three radiator options: corrugated, panel-type, and tubular types. You can select the appropriate type based on application requirements.
Customizable High-Protection Enclosure
The transformer enclosure can be configured with an IP55 or higher protection rating, ensuring excellent resistance to moisture, dust, and salt spray for reliable outdoor operation.
stable core structure
The transformer core adopts a stepped three-limb construction. This can effectively reduces no-load loss and operational noise.
