Advantages of Dry-Type Transformers

  1. High Safety: Dry-type transformers do not use cooling oil, eliminating the risk of oil leakage, fire, and explosion. This significantly enhances the safety of the transformer.


  1. Environmental Friendliness: Dry-type transformers have a lower environmental impact as they do not require cooling oil. They do not generate hazardous substances, making them suitable for sensitive environments and special locations such as medical facilities, office buildings, and commercial centers.


  1. Low Maintenance Cost: Dry-type transformers have lower maintenance costs compared to oil-immersed transformers. They do not require oil sampling, oil testing, and maintenance of oil tanks, making maintenance simpler and more cost-effective.


  1. Durability in Harsh Environments: Dry-type transformers utilize special insulation materials that enable them to withstand high temperatures, humidity, vibrations, and chemical corrosion in harsh environments. This makes dry-type transformers suitable for industrial and outdoor applications.


  1. Compact Size: Dry-type transformers are typically more compact than oil-immersed transformers, requiring less space. This makes them suitable for installation and placement in limited-space areas.


Disadvantages of Dry-Type Transformers:


  1. Inferior Heat Dissipation: Dry-type transformers have slightly poorer heat dissipation performance compared to oil-immersed transformers. As they do not utilize cooling oil, they require additional cooling devices to maintain proper operating temperatures.


  1. Higher Initial Investment: Dry-type transformers have a higher initial investment cost compared to oil-immersed transformers. This is due to the specialized insulation materials and cooling systems required to ensure their performance and safety.


In conclusion, dry-type transformers offer several advantages, including high safety, environmental friendliness, low maintenance costs, durability in harsh environments, and compact size. However, they also have some disadvantages, such as inferior heat dissipation and higher initial investment costs. When selecting a transformer, it is important to consider these factors in accordance with the specific application requirements to ensure the optimal choice of type and specifications.
