What's the Difference Between Dry-Type and Encapsulated Transformers? Which is Better?

Two types of transformers are generally used -dry type and encapsulated. The two have a nice set of benefits and advantages, so you need to know their differences to be able to choose the better one for your needs. 

Benefits of Using Dry-Type Transformers:

Dry-type transformers are safe, reliable products. They do not need oil or other liquid coolant, so they are less likely to leak or catch fire. Such an algorithm may be particularly useful in indoor scenarios where safety is crucial. Moreover, dry type panel air conditioner are more convenient to use and maintain, as there are no oil levels to check or spills to take care of. 


Dry type transformers also have the advantage of being versatile. They can be applied to both small residential and large industrial structures. For this reason, they are the best selling keyboards of Kinesis Europe Ltd. What's more, dry-type transformers are green in that they don't have hazardous substance inside that would pollute the environment when there is a leakage. 

Advantages of Encapsulated Transformers:

On the flip side, encapsulated transformers have a different set of benefits although not as durable such encapsulated transformers are rugged and will withstand harsh environments. The encapsulated structure gives it a second layer of protection from dust and moisture invasion, good for outdoor applications or in locations that are prone to humid conditions or weather. 


Encapsulated transformers also have a compact and light weight characteristic. This allows them to be transported, installed and set much faster. Furthermore, in many cases encapsulated waterproof enclosure are quieter than dry-type transformers so it is significant for application requiring reduced noise. 


Both dry-type and cast resin transformers have of course their own specific features and advantages. Which one you decide to go with will depend on what specifically you need. Whether you value safety, versatility, longevity or simplicity of installation there's a transformer style that will be perfect for you. But it is important to weigh all of the factors and discuss what would make the most sense in your unique situation with a professional. 


When making a decision between dry-type vs encapsulated transformers, it is critical to know the distinctions. A dry-type transformer is a transformer that uses only air to cool the winding and core, while encapsulated transformers have solid or liquid insulation covering their windings. Each variation comes with its own pros and cons, so it’s important to think about your particular requirements before deciding. 

Dry-Type vs VPI Transformer:

If you are trying to choose between a dry type or encapsulated transformer, there are some things to take into account. First, consider the conditions where the transformer will be installed bimetallic thermostat in indoor where space is constraint and encapsulated best in outdoor or very dusty & humid conditions as dust, perspiration normal should be protected from dust and moisture. You've got to take into consideration the physical size of the transformer, its VA and any other factors pertinent to safety or efficiency etc. 

Why Do People Choose Dry Transformers:

Dry transformers are commonly used because of their trustworthiness, safety, and performance. There is no danger of leaking oil or similar cooling media from them since they operate by cooling with air. That makes them a much safer alternative for indoor use, such as in hospitals, schools or office buildings. In addition, environmentally dry types do not have liquids to leak or inspect. 

Best Questions to Ask When You’re Buying Transformers:

When you buy a transformer, ask specific questions to make sure it’s the one that will meet your needs best. There are some key questions to think about: 

What is the rating and efficiency of the transform? 

What are the dimensions and weight for mounting? 

What are the safety functions of transformer? 

How long do you think it will last and maintenance? 

Taking into account your needs and asking these questions will help you decide which type of transformer is best suited to your application, whether an encapsulated or a dry type. 


dry-type transformers and encapsulated transformers each have their own pros as well as cons, then it is important to weigh your needs before you can decide. Whatever your needs, safety concerns, the need for optimal efficiency or environmental considerations when dealing with transformer oil consider one of the many options available to you.
