Frequently Asked Questions (FAQs)

What are the common types of 3-phase transformers produced in Chinese factories?

In Chinese factories, you can find a variety of 3-phase transformers to meet different needs. These include oil-immersed transformers, dry-type transformers, pad-mounted transformers, and pole transformers. Each type has its unique advantages, such as the oil-immersed transformers offering high efficiency and the dry-type transformers providing safety and low maintenance. These variations ensure that you can select the best transformer for your specific application and environment.?

What are the standard voltage and capacity ranges for 3-phase transformers in China?

Chinese manufacturers like Daelim produce 3-phase transformers with a wide range of voltage and capacity options. The rated voltage can go up to 230kV, and the capacity can reach up to 60MVA or even higher in some cases. These transformers can be customized to fit your specific requirements, including different frequency settings such as 50Hz or 60Hz.?

How do Chinese 3-phase transformer manufacturers ensure quality and reliability?

Chinese manufacturers, such as Daelim, adhere to strict quality control and international standards like ANSI/IEEE, CSA, AS, and IEC. Each transformer undergoes routine tests before leaving the factory, and additional special tests can be conducted based on customer requirements. This rigorous testing ensures high reliability and performance of the transformers, making them suitable for various industrial and commercial applications.?

What are the advantages of using 3-phase transformers in industrial and commercial settings?

Using 3-phase transformers offers several benefits. They provide a steadier and more constant flow of power due to the balanced load across the three phases. This results in improved reliability, reduced voltage drops, and lower current requirements. Additionally, 3-phase transformers are more economical in terms of power transmission and distribution, saving on conductor material and reducing the cost of equipment.?

How are 3-phase transformers typically connected and configured?

3-phase transformers can be connected in several configurations, including star (Y) and delta (mesh) connections. The star connection has a neutral point, while the delta connection forms a closed loop without a neutral point. Common configurations include Delta-Delta (D/D), Star-Star (Y/Y), and Star-Delta (Y/D). Each configuration has its own advantages and is chosen based on the specific needs of the power system.?
