Application of Dry Type Transformer in Power System
As an indispensable part of the power system, the epoxy resin cast dry encapsulated transformer not only converts high-voltage power into low-voltage power, but also plays an important role in the stability of the power grid, power quality, power grid security and so on.
1. Improve power grid stability
Dry transformer has high insulation grade and insulation strength, which can effectively prevent equipment failure and electrical failure. At the same time, its small size, light weight, occupying less area, has a positive role in promoting the stability and reliability of the power grid.
2. Improve power quality
The high efficiency and low loss of dry transformers can greatly improve power quality and reduce energy waste. At the same time, its oil-free design also avoids the influence of oil pollution on power quality, making the quality of power more stable and reliable.
3. Improve grid security
The dry transformer has high safety, and the oil-free design avoids the impact of oil leakage and oil pollution on the safety of the power grid. The insulation material of the dry transformer is not easy to age, which can ensure the safety and reliability of the equipment for long-term operation.
three phase dry type transformer

Epoxy resin cast dry encapsulated transformer advantages is as below.
1. High security
Dry transformers use dry edge materials, unlike oil-immersed transformers, it does not require oil cooling, so there is no oil leakage and oil contamination. This oil-free design not only greatly improves the safety of the equipment, but also reduces the pollution to the environment and makes it more environmentally friendly.
2. Low maintenance cost
Because dry-type transformers do not require refueling, their maintenance costs are greatly reduced. Because the insulation material of the dry transformer is not easy to age, its life is longer than that of the oil-immersed transformer, which also saves the cost of maintenance and replacement of the equipment for the user.
3. Wide range of application
The dry transformer is small in size and light in weight, and is suitable for various occasions. For example, it can be used in basements, high-rise buildings, ships and other places where space is limited. Dry transformers can also be used in explosion-proof sites and strong electromagnetic interference environments.
