Open type dry transformer

Open type transformer is a commonly used process for manufacturing power transformers. Its advantage is low cost and relatively low manufacturing cost. However, open type dry transformers are greatly affected by environmental factors such as corrosion, humidity, temperature, etc., which can lead to a decrease in accuracy and precision. At the same time, mechanical impact of open type dry transformers can easily cause local breakdown. In addition, the installation and maintenance process of open type dry transformers is relatively complicated, requiring certain professional skills and a high-level construction environment, which also increases manufacturing costs.

Compared to open type, epoxy casting is a more advanced process. The advantages of epoxy casting are high precision, customized capacity, voltage, etc. according to customer needs, and better resistance to moisture and corrosion. At the same time, epoxy casting also has a very good effect on reducing noise, low-frequency magnetic leakage, and insulation of high-voltage parts. Although epoxy casting is relatively expensive, its stable performance and simple maintenance increase the service life of equipment, making it essential for the long-term operation and high demand use of power transformers.

summary

both open type and resin cast type have their own advantages and disadvantages. For the manufacturing of a single power transformer, an open type transformer is more economical and practical; But for group production or customized production, the design differences of each equipment for epoxy casting are relatively small, and the mechanical strength and impact capacity are also better, which can improve the safety and stability of equipment use.
