What is the alarm temperature of the dry-type transformer

dry type transformer

What is The Alarm Temperature of The Dry-type Transformer? 1. At present, most dry-type transformers use H-class insulating materials, so generally the temperature of dry-type transformers should be below 180°C. 2. When class A insulating material is used, the maximum transformer temperature rise should be less than 60K when its limit working temperature is 105℃; when class […]

What’s the difference between dry-type and oil-immersed transformers

_Dry-type Transformer (8)

Detailed explanation of the difference between dry-type transformers and oil-immersed transformers Dry-type transformers use air to dissipate heat, and oil-immersed transformers use oil as a medium to dissipate heat. When it comes to the difference between dry-type transformers and oil-immersed transformers, we must also pay attention to the power comparison between the two. The former has […]
