Oil Transformer vs Dry-Type Transformer: Which Is Better?

There are two primary types of transformers, oil transformers and dry-type transformers. Both have some unique qualities and many people find themselves asking the question which one is better. At Dingxin Electric, we know that the type of cast resin dry type transformer you choose should be based on your needs. Oil transformers are packed with oil and the oil is what cools and insulates the transformer. Dry-type transformers use air for both cooling and insulation. This article will take a look at the advantages of both types and what you need to know especially from a wholesale buyers perspective, and how dry-type transformers perform more efficiently. 

What Wholesale Buyers need to know when choosing a transformer? 

When wholesale buyers need to decide which transformer to purchase, value is a key component. Oil transformers do have an advantage, they are more powerful within a smaller package size. This means that if you need to buy an oil transformer and have space limitations, oil might be the right choice. Also, they perform quite well for high voltage applications. There is a downside to the oil transformer; leaks may occur and they may harm the environment and you will have to routinely check and maintain oil levels. 

Dry-type transformers on the other hand have less of an up keep required from you. Since there is no oil inside, there is less chance of a leak which is important for any building which is to be indoor. Dry-type transformers also weigh less which could potentially save money in installation costs. For wholesale buyers, this can add up and turn out to be a better deal over time. It seems that many businesses prefer the dry-type transformer in a large urban area where there is a high level of people or activity. 

Why Dry-Type Transformers Outperform Oil Transformers on Efficiency? 

The topic of efficiency with transformers goes back to dry-type transformers being better than oil transformers. To begin with dry-type transformers operate at a better energy efficiency. That is, they do not waste as much energy during operation and this will result in lower electricity bills. This is important for any business that has a transformer powering it since that is the electricity that they are paying for. In other words, less energy wasted, the better it is for your company and the environment. 

Another point on the efficiency topic is that dry-type transformers can withstand a larger operating temperature range. What this means is that the dry-type transformer can handle a changing environment better than an oil transformer. An oil transformer can get too hot and eventually over heat. This will cause damage to the oil transformer. A dry-type transformer however can handle higher temperatures without as much of a negative outcome. This makes dry-type transformers useful in regions that experience extreme temperature fluctuations. 

Also dry-type transformers are designed with smaller and more compact designs in mind. This means they will take up less space in factories or buildings. Dry-type transformers are lightweight too which could potentially cut back on installation expenses. In fact some businesses find that they can cut back on costs simply from using dry-type transformers because it is so much simpler and quicker to install. 

At Dingxin Electric, we believe that the best transformer is always one that meets the needs for efficiency and application. A dry-type transformer offers so much to a business by cutting back on costs and operation safety. Their performance capabilities during an increasing array of situations with less energy wastage really highlight the strengths of a dry-type transformer compared to oil transformers. 

In summary, oil and dry-type transformers both have their advantages and disadvantages, but for wholesale buyers that value efficiency, safety and economic efficiency, it is generally better to go with a dry-type transformer. Taking these aspects into consideration will allow any business to make the best choice possible. 

Cost advantages of dry type transformers are also quite notable in terms of bulk purchases for businesses. 

Firstly, dry type transformers work by using air cooling which removes oil from the internal system of the transformer. This ensures that they are safer and more practical for maintenance. Since there is no oil, there is little chance of a leak which could cause a costly problem for both the environment and the business. When purchasing dry type transformers in bulk, there are significant savings to be found on these units. Dry type transformers will generally last longer than the alternatives making it a smart investment to cut back on costs of replacement and repairs over time. Dingxin Electric provides quality and cost effective dry transformer that are ideal for the budget conscious company that does not want to sacrifice quality. Furthermore, they are easy to install. They don't require any oil so there is no lengthy and complicated setup process like oil transformers require. This additional ease of installation also brings down costs and will make dry type transformers more affordable to put in place. The use of dry type transformers in wholesale quantities can bring about great savings to businesses everywhere. 

If a business needs reliable suppliers of both oil and dry-type transformers, then the reputation of that supplier is key. Reputable suppliers are the ones who are generally held in good esteem by their customers. They do their best to ensure that their customers are happy with the quality of their transformers and service. Dingxin Electric stands out for having a good reputation with quality products. A second factor in choosing a supplier is their experience in the business. If a supplier has been around a long time, then they are more likely to know what they are doing. When you choose a supplier, they must offer both types of transformers as that will allow a business the option to make the best decision based on the requirements of their business. Asking about the warranty that the company provides can also help determine the quality and reliability of a company. That warranty covers a business if they encounter problems. Finally, companies that offer volume discounts can help a business save more money when purchasing large numbers of transformers. If you attend trade shows, you can also meet many of these suppliers face to face. These are just a few of the things that go into selecting a reliable supplier of transformers. 

The quality and efficiency of an oil or dry-type transformer can be impacted in several ways. 

First, you must know what environment a transformer will be in. Outdoor transformers that have to withstand many conditions tend to perform better outside, as they were designed for it, while dry-type transformers are more suited to operate inside. A dry-type transformer will still be efficient in many outside areas, so long as it is properly protected from the elements. You will want to also consider the load that will be put onto the transformer and make sure that a transformer can perform as it needs to without overloading the device. Oil transformers and dry-type transformers are made in many different sizes and capacities, to make sure to find one that fits your needs. Proper maintenance is very important for both transformers. With oil transformers, you want to be on the look out for leaks while keeping your eye on the oil level. A dry type transformer, though, will want to remain free from dirt and debris, which could be very detrimental to the lifespan of a transformer. Lastly, the quality of the materials used in the transformer will make a big difference in how it operates and its durability. It is important that you find a company like Dingxin Electric, that takes pride in using the highest quality materials.
