There are two main reasons for the aging of dry-type transformers. First, dry-type transformers are used for a long time. The functions and components of dry-type transformers that have been working for a long time are gradually aging. Corrosion of the switch leaf, etc., it is difficult to close to the specified position, which may cause an accident. Second, the normal use of the device will cause aging. For example, temperature has a great influence on the life of dry-type transformers. If the temperature of the insulating material is too high during operation, the life of the dry-type transformer will be shortened.

Oil-immersed transformers play an important role in many engineering constructions, especially in some power plants, large factories, and construction sites. Oil-immersed transformers can be seen everywhere. Oil-immersed transformers have been widely used due to their low cost and stable performance. But we still have some matters needing attention in the process of using oil-immersed transformers. What do we need to pay attention to when using oil-immersed transformers? The capacity expansion of oil-immersed transformers is an important feature of oil-immersed transformers. The capacity increase of oil-immersed transformers is to increase its capacity, but there are many problems that need to be paid attention to. Common oil-immersed transformers need to be increased in capacity. What are the issues to pay attention to?

The use of oil-immersed transformers is to use its efficiency. If the efficiency is high, the function of the transformer will be better played. In fact, oil-immersed transformers are realized by efficiency in economic construction. There are many factors that affect the efficiency of transformers. How much is the efficiency of oil-immersed transformers generally?

Epoxy resin transformers can be used as replacement products for oil-immersed distribution transformers. They are products with better performance among all kinds of dry-type transformers. They are especially suitable for urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, underground power stations, laboratories, stations, docks, airports, combined substations and other important places.

Under normal circumstances, either oil-immersed transformers or dry-type transformers can be used, such as independent or annexed substations in industrial and mining enterprises, agriculture, and residential areas. Transformers that can be selected include S8, S9, S10, SC(B)9, SC(B)10, etc.

Transformer cooling is an important aspect to consider during transformer design and operation. It is crucial to maintain a safe operating temperature for the transformer's components and to extend its lifespan. There are different cooling methods available for transformers, including air cooling, oil-immersed cooling, and water cooling.

Dry type isolation transformers have many advantages over other types of transformers. These transformers are specially designed for use in areas where hazardous materials cannot be used due to safety concerns. Here are some of the advantages of dry type isolation transformers:

Due to the large number of rural lighting lines, most of them are single-phase power supply, and the randomness and inadequate management of jumpers in the construction, the load of distribution transformer is in phase deviation operation. Long term use leads to the aging of the insulation of a phase coil and the burning of the transformer.

With the continuous acceleration and development of China's modern industry and the further improvement of the level of social development, people have higher and higher requirements for iron and steel products in their daily lives. For the increasing attention of environmental protection countries, clean energy and materials are more important.
