In the 1980s, the annual output of epoxy resin cast transformers was about 1000MVA, and by the 1990s, it had exceeded 10000MVA. The insulation class of Dry-type transformer has covered Class B, Class F, Class H, and Class C. Next, let's take a look at the Dry-type transformer structure types and structural features. Here are some answers.

Because a Dry-type transformer has the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, small size, low noise, etc. It is often used in places with high-performance requirements such as fire prevention and explosion protection. Next, let's take a look at the overload capability and working principle of the Dry-type transformer. Here are some answers.

Liquid Insulated Transformer is the main equipment for power transmission and distribution in the power system. Liquid Insulated Transformer mainly reduces the high-voltage power of the grid to 600 volts (V) or 380 volts (V) that can be used directly to supply power to electrical equipment. So how does the fire and explosion protection of Liquid Insulated Transformer work? Let's take a look together next.

The safe operation of the Dry-type transformer and its service life depends largely on the safety and reliability of the transformer winding insulation. Next, let's take a look at the inspection and protection device of the Dry-type transformer. Here are some answers.

We know that the liquid-cooled transformer is used in our lives to facilitate our production and life. We also have some problems with the liquid-cooled transformer, so the common problems and solutions of the liquid-cooled transformer what is it then? Let's take a look together next.
