Have you ever wondered how electricity gets transported to our homes, workplaces, and all regions? Does it come directly from the power plants? Well, no! Not until you want an explosion. This is where the role of electrical transformers comes into play.
The transformers are devices that convert high voltage electricity into low voltage electricity making it safe for use for commercial and industrial purposes like factories, homes, etc.
Transformers are of mainly two types, namely, dry-type electrical transformers and liquid transformers. Even though they serve the same purpose, they are different in their ways of working, environment, and situations.
We, at Electric Power Inc., are the manufacturers of custom-engineered dry-type transformers, all of which meet the UL and CSA standards. With our team of engineers, we work to provide complete customer satisfaction and test all the products before sending them out.
Difference between dry-type transformers and liquid transformers
When the transformers work to convert electricity into low-voltage, they dissipate energy. This makes it essential for them to cool down alongside. So, the major difference between both types of transformers is their cooling process. If they don’t cool down during the process, it can be hazardous and combustive.
Dry-type electric transformers
The dry-type transformers are static, in which air acts as the cooling medium. During the conversion process, when the unit starts heating up, the fire-resistant insulation along with air prevents any potential explosions and hazards.
They mainly serve the applications of small and medium voltages. The dry-type electrical transformers are ideal for use in commercial, utility, and industrial uses. Alongside, these also contain windings of copper and aluminum. Based on the environment and working conditions, you can choose the most suitable dry-type transformers. Even though these have a high upfront cost, the profit margins so obtained are even higher.
At Electric Power Inc., we engineer transformers that deliver optimum results, providing high-efficiency and advanced design. This leads to cost-effective energy output. We provide several models with varying sizes, frequencies, phases, voltages, and ratings ranging up to 500 kVA. Alongside, we also ensure that all the safety and shipment standards are met.

Liquid electrical transformers
The cooling method of liquid electrical transformers varies as compared to dry transformers. It converts the high voltage power to usable energy sources, by using mineral oils along with fans as a cooling method. Some other liquid transformers use hydrocarbons and silicones, which are safer methods. The fluids are a faster solution for cooling, leading to a reduction of high temperatures for the unit’s coil. These are best used for medium and high-voltage purposes.
These transformers are more efficient as compared to dry transformers, and operate even quietly.
Factors of difference between dry-type transformers and liquid electrical transformers
The differences among both the types of transformers which can be taken note of and the factors affecting them are as follows:
Maintenance:
The liquid transformers require high maintenance as compared to dry ones. It requires more upkeep including inspection, tightening of connections, and check the liquid levels. While on the other hand, the dry transformers have resistance towards chemical contaminants. Alongside, regular cleaning is to be done for the transformer’s coils, grills and elements and look for loose connections.
Price:
In most cases, the dry-type transformers are a little expensive as compared to oil-type transformers, considering their efficiency and outputs.
Sound:
During the operations, the transformers usually make a lot of noise. However, the liquid-type electrical transformers are quieter than the dry ones.
Efficiency:
The liquid transformers have an edge over the dry transformers considering their size and voltage. In case of excessive load, the dry transformers tend to heat up faster.
Even after all these factors, choosing the transformer varies according to the situation and environment it is required for. Always ensure that you choose reliable manufacturers of electrical transformers, else, it could lead to huge losses. Also, it undoubtedly is a sound investment for all organizations.
Benefits of types of transformers
Dry-type transformers:
The benefits offered by using these transformers are enlisted below:
- Cuts down environmental pollution alongside reducing any risk due to spills and oils
- No fire-proof enclosure is required
- The inspection process is easy, alongside removing coils and connections
- The chances of fire hazards are reduced
- Considering the safety purposes, these are ideal for indoor purposes
- They have a simple installation process
- Easy to maintain
- Can be practically used for low and medium voltage purposes
- They have high resistance towards short circuits
- They can fit well in damp areas
Liquid transformers:
The several positive attributes of the liquid transformers are as follows:
- The process of repairing and recycling is easy
- They have a longer lifespan
- The sound level during operations is low
- These are highly efficient
- They can withstand high voltages
- Minimal environmental impact
- Smaller footprint
We at Electric Power Inc., understand the importance of efficient and reliable transformers and hence provide our consumers with the same. We are among the optimum manufacturers of dry-type transformers offering them in a wide range to serve versatile applications.
Conclusion:
To summarize, even though both types of transformers serve similar purposes, each of them has its list of pros and cons. So, before you purchase, you can check the above details to help you make the right decision. Know your purpose and choose the one that fulfills it in the right way.
