FAQ

1.What are the Medium-term measure safety precautions for oil-immersed transformers?

Check and rectify the power failure of the same type of products

2.What are the long-term measure safety precautions for oil-immersed transformers?

We will improve the technical specifications for oil-immersed transformers and high-resistance equipment, and put forward specific requirements for metal-shielded Casings.

3.Is there radiation from the box transformer?

High operating voltage machines and equipment are not electromagnetic induction pollutants, households do not need to worry about electromagnetic radiation damage.


Latest News

When refueling oil-immersed transformers, the oil should be close to the oil from the lower oil valve, which is convenient for gas discharge, but it should be injected through the oil conservator when refilling the oil. Prevent the gas volume from being stored in a certain position of the body or in the gas relay, causing local insulation to decrease or malfunction.
