According to the six degree rule of transformer insulation aging, yuete company has optimized the design and improved the internal heat dissipation conditions of the transformer through solid technology, so that the hottest spot temperature of the transformer is greatly reduced, so as to effectively prolong the service life of the transformer.

The internal heat dissipation conditions of the transformer are improved, so that the load bearing capacity of the transformer is greatly improved.
At full load, the service life of the transformer is 5 to 10 years longer than that of the ordinary transformer. (the current national standard design is 20 years)
