FAQ

1.What kinds of tests should be done for oil-immersed transformer in operation?

Temperature test;Load test;insulation resistance test

2.How many meters of radiation from the transformer is harmful?

The electromagnetic radiation of ordinary distribution transformer is not large, and the metal shell can shield a considerable part of the electromagnetic radiation from the transformer generally within 5 meters to have an impact.

3.What is the main principle of anti-theft lock for a transformer?

Its main principle: the main body of the transformer cover plate bolts placed in the anti-theft shell, and then use special tools to bolt the live block, gland seal, so as to achieve anti-theft purpose.


Latest News

The temperature of the transformer is very important and is an important feature affecting the operation of the transformer. Therefore, the transformer needs temperature. If the temperature is abnormal, it has a wide range of effects on the operation of the transformer, especially in summer, the transformer is relatively high in temperature. The effect on the operation is relatively large.
