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:

1. High reliability: Due to the absence of liquid insulation, dry-type transformers are not prone to liquid leakage during operation, thus offering higher reliability.
2. Environmentally friendly: Dry-type transformers do not require fire and explosion protection equipment, and do not produce toxic gases, making them more environmentally friendly.
3. Easy maintenance: Dry-type transformers do not require maintenance and inspection of cooling systems due to the absence of cooling liquids, reducing maintenance costs and workload.
4. Wide applicability: Dry-type transformers can be used in various environments, including residential areas, commercial areas, and industrial areas.

However, compared to oil-immersed transformers, dry-type transformers have some disadvantages that need to be considered:

1. Poor heat dissipation: Dry-type transformers have poor heat dissipation, resulting in lower power density and limited application in high-capacity transformers.
2. Large volume: In order to improve heat dissipation, dry-type transformers typically require larger volumes.
3. High manufacturing cost: The use of special solid insulating materials and heat dissipation structures make the manufacturing cost of dry-type transformers relatively high.

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:

1. 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.

2. 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.

3. 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.
