Dry-type transformer is a type of transformer that does not use liquid insulation. It uses dry solid insulating material to isolate and support the coils, and has a certain cooling system.
The main characteristics of dry-type transformers include:
However, compared to oil-immersed transformers, dry-type transformers have some disadvantages that need to be considered:
Overall, dry-type transformers have obvious advantages in specific applications, but also have some limitations. When selecting a transformer, various factors need to be comprehensively considered according to actual needs.

Dry-type transformers are packaged using various methods, each with its own advantages. Here are the common packaging methods and their benefits:
Wooden crate packaging: Dry-type transformers are placed in sturdy wooden crates to provide excellent physical protection, preventing damage from impacts and vibrations during transportation. Wooden crates also help isolate the transformer from moisture and dust, maintaining the proper working environment.
Cardboard packaging: A layer of hard cardboard is wrapped around the outside of the transformer, offering protection against surface scratches and abrasions. Compared to wooden crates, cardboard packaging is lighter and more suitable for smaller dry-type transformers.
Plastic film packaging: The entire dry-type transformer is wrapped in plastic film, effectively isolating it from dust, moisture, and minor collisions. This packaging method helps keep the transformer clean and operational.
The advantages of these packaging methods include:
Transformer protection: Packaging provides physical protection, safeguarding the transformer from damage during transportation and handling. It is particularly effective in isolating external factors such as dust, moisture, and minor collisions, ensuring the transformer's integrity and functionality.
Convenient transportation: Proper packaging makes the transformer easier to handle and transport, reducing friction, vibration, and the risk of accidents during transit.
Safety maintenance: Packaging effectively prevents accidental contact and injuries, ensuring the safety of personnel involved in handling and transportation.
