What are the three types of dry-type transformers?

The three types of dry-type transformers are dry-type cast wound transformers, dry-type reactors, and dry-type isolation transformers.

1、 Dry type cast winding transformer

Dry type cast winding transformer refers to the use of dry-type winding materials for the windings of transformers. Cast wound dry-type transformers are manufactured by first making castings and then winding copper or aluminum coils on the castings. Its main characteristics are good thermal insulation, insulation, and moisture resistance. It can withstand high loads and short-circuit currents, and has good technical and economic benefits. It is suitable for high-rise buildings, basements, and other places with high load requirements and complex usage environments.

2、 Dry type reactor

Dry type reactor refers to the use of dry winding materials to produce high reactance components. The inside of the reactor is made of hollow cylindrical winding, and the outside is made of high temperature and high voltage resistant materials such as glass fiber and epoxy resin. The main characteristics of dry-type reactors are oil-free, gas free, and pollution-free, making installation and maintenance very convenient. They are suitable for power systems and industries such as mining and metallurgy that require reducing harmonic interference.

3、 Dry type isolation transformer

Dry type isolation transformer refers to a completely oil-free dry-type transformer made of dry-type unique isolation materials. The main characteristics of this transformer are no fire, no environmental pollution, ultra-low noise, no oil leakage, strong weather resistance, etc. It is widely used in hotels, shopping malls, subways, airports, hospitals and other places to prevent fires and environmental pollution.

In short, dry-type transformers are a type of transformer that is free from oil pollution, requires no maintenance, has a long cycle, is safe and reliable, and has a wide range of applications. According to their functions and application scope, they can be divided into three categories: dry-type cast wound transformers, dry-type reactors, and dry-type isolation transformers. Choosing appropriate models and specifications can better meet their needs in different application scenarios.
