Current transformers can be sealed using different materials, which include epoxy resin, oil, or gas. The insulators are helpful, especially to the outdoor transformers. This is because they protect them against the forces of nature, like rain, high altitude, and UV rays. Companies like, Guangdong Sihui Instrument Works has worked hard to produce the best indoor and outdoor current transformers. They remain our number one option whenever we need to get a transformer. The reason is that all their products have high standards of quality. You can rely on them to deliver transformers and insulators that are durable. Read on as we share with you some in-depth insights about the different types of seals.
Epoxy Resin Insulation Transformer
Transformers are cast with a mixture of epoxy resin, which can make them fit for installation. The epoxy resin can be used for dry-type transformers. This means that when they are installed outside, they can be reliable. You will be impressed with their performance because they can withstand all kinds of weather. An epoxy resin insulator transformers will not corrode even when there is acid rain. When cast with epoxy resin, this type of transformers does not pollute the environment. Besides, you won’t need to spend a dime on maintenance costs. Epoxy resin insulation transformers are money savers.
You can also use the epoxy resin insulation transformer for all areas such as homes and business centers. This multi-purpose transformer has automatic extinguishing. This means that your safety is highly-guaranteed. If it is installed inside your house, it can mitigate fire risks. The casting process of Epoxy Resin Insulation Transformer includes the use of a vacuum to make sure that the epoxy resin is uniformly mixed. In particular, epoxy resin can be mixed with quartz flour, which makes it even stronger. This makes the windings resistant against any short-circuits. In this way, you can be assured that there will be no partial discharge risks.
Oil Insulation Transformer
In this case, the transformer is fully immersed in oil. This is to preserve the windings and the core transformer. The oil works in a way that cools down the transformer’s temperature. In other words, it is used as a coolant. This helps a lot with the high voltages that might raise temperatures with time. Oil insulation prevents arcing, and the electrical discharge called the “corona discharge”.
When the transformer is insulated using oil, it averts any oxidation, so oil acts as a shield against cellulose and oxygen. Thus, it does not get oxidized, affecting its performance. This way, if you have an outdoor transformer, it will start to erode. But with the oil, there is no need to panic. It is already sorted with the oil insulation properties that offer protection from any damages. The only drawback to the oil insulation transformer is that it can pollute the environment. When it is placed near a water body, it can be harmful to marine life. However, if it’s strategically located, this risk can be minimized.
Gas Insulation Transformer
A transformer that is insulated with gas is safe to be used both outdoor and indoor. It is also used as a cooling agent whenever heat spikes up. As for the gas used, it is mainly Sulphur hexafluoride, which is commonly known as SF6 gas. The gas is eco-friendly and can be recycled. You will be safe when using a gas insulation transformer because it is not flammable. It balances the tank pressure making it secure.
Another significant benefit of a transformer insulated with gas is that it is a non-pollutant. Therefore, if it is installed in public areas, it is safe for all people. It will not cause any respiratory disease or any other health problems. The transformer is resistant to any impulse voltage. This shows that when you are using a gas insulation transformer, you can forget about the risk of an excessive voltage. Modern companies nowadays made great efforts to make sure that the electric field is at a balanced strength.
Therefore, the three types of seal are unique, while each one has its advantages and disadvantages. As for the oil insulation transformer, it can be great for outdoors. The epoxy resin and gas transformers are both high for all areas. They can do well inside and outside buildings. Whatever the type of transformer and insulator you are looking for, Guangdong Sihui is worth mentioning for its exemplary work. Its team of experts has made excellent strides in making sure we are all safe. This company has received many awards for manufacturing products that are environmentally safe. They meet all the safety and health standards. Thus, we would vouch for the quality of their products and extraordinary service.
