Introduction to Dry - type Transformers
Dry - type transformers are power transformers where the core and windings are not immersed in insulating oil. Instead, they use solid insulation materials. These transformers offer several advantages over their oil - immersed counterparts. They are more environmentally friendly as they do not pose a risk of oil leakage and fire associated with oil - filled transformers. They are also suitable for indoor installations, such as in commercial buildings, hospitals, and data centers, due to their low fire hazard and low noise operation. Dry - type transformers have high reliability, good heat dissipation performance, and can withstand short - circuit currents well. With the continuous development of the power industry, the demand for dry - type transformers is increasing, and many Chinese factories have emerged as leaders in this field.
