Dry type transformers use air as a cooling medium, making them suitable for indoor applications. They are typically safer due to the absence of flammable oil. This makes them an ideal choice for places where safety is a priority, such as schools and hospitals.

On the other hand, oil immersed transformers utilize oil for insulation and cooling. This type can handle higher loads and is often more efficient than dry type transformers. However, they require careful handling and maintenance to prevent leaks and environmental contamination.

Medium Voltage Transformers in China

In China, medium voltage transformers are produced in large quantities, catering to various industrial needs. These transformers are crucial for stepping down voltage levels in power distribution networks, ensuring that electricity reaches consumers safely and efficiently.

Chinese factories have adopted advanced technologies to improve the quality and efficiency of medium voltage transformers. With fast production timelines, suppliers can meet the increasing demand without compromising on quality. This has made China a competitive player in the global transformer market.
