What is an Unencapsulated Class H Dry-Type Power Transformer?

Basic Definitions:

• Non-encapsulated: It means that the coils of the transformer are not subjected to the traditional encapsulation treatment but are directly exposed to the air. This design can improve the heat dissipation efficiency and extend the service life.

• H-Class Insulation: H-Class insulation materials refer to those insulation materials that can withstand a maximum temperature of 180°C. They possess excellent heat resistance and electrical properties.

Structural Characteristics:

• Coil Structure: The non-encapsulated structure is adopted, with the coils being directly exposed to the air, which is beneficial for heat dissipation.

• Insulation Materials: H-Class insulation materials such as NOMEX paper and fiberglass are used, featuring excellent heat resistance and electrical properties.

• Iron Core: It is usually made of laminated high-quality silicon steel sheets, with the characteristics of low loss and low noise.

• Cooling Methods: Generally, natural air cooling (AN) or forced air cooling (AF) is employed. The appropriate cooling method is selected according to specific application requirements.
