Dry type transformers: why has it become the first choice for safety and energy conservation in modern buildings and data centers?

In today’s pursuit of safety and sustainable development, dry-type transformers are rapidly replacing traditional oil immersed transformers. This article will delve into the core advantages of dry-type transformers and reveal how they have become indispensable power centers in key areas such as high-rise buildings and data centers.

Dry-Type Transformers: The safe, clean, and efficient heart of modern power distribution.

1.What is a dry-type transformers? The fundamental difference between it and traditional transformers

Simply put, dry-type transformers are transformers that do not use liquids (such as transformer oil) as insulation and cooling media. On the contrary, its iron core and winding rely on air and sturdy solid insulation materials (such as epoxy resin) for insulation and heat dissipation.

1.1 Core difference: Safe and oil-free

Traditional oil immersed transformers are filled with mineral oil inside. Although the cooling effect is good, there is a risk of oil leakage, flammability, and even explosion. Dry type transformers completely eliminate this hazard because they do not require oil at all.

1.2 Strong adaptability and easy installation

Due to the absence of oil pillows and tanks, dry-type transformers have a more compact structure and lighter weight. Therefore, it can be easily installed in the core area of buildings, even directly near the power load center, greatly reducing power transmission losses.

2.The three core advantages of dry-type transformers directly address industry pain points

The popularity of dry-type transformers is due to their excellent performance, which perfectly meets the demanding requirements of modern power applications.

2.1 Ultimate safety, eliminating fire hazards

This is the most prominent advantage of dry-type transformers. The materials it uses, such as epoxy resin, have the characteristics of flame retardancy and self extinguishing. Even under high loads or extreme conditions, it will not burn or explode. Therefore, it is particularly suitable for places with extremely high fire prevention requirements, such as:
High rise office and residential buildings
Personnel intensive shopping malls, hospitals, and schools
Transportation hubs such as subways and airports

2.2 Green and environmentally friendly, easy to maintain

Dry type transformers do not use oil, so there is no risk of oil leakage contaminating soil and groundwater. At the same time, it operates with low noise and is a truly “environmentally friendly” device. In addition, it does not require regular oil quality checks and filtration like oil immersed transformers, greatly reducing maintenance workload and lower lifecycle costs.

2.3 Efficient and energy-saving, in line with sustainable development

Modern advanced dry-type transformers commonly use high-quality silicon steel sheets and amorphous alloy iron core technology. These materials can significantly reduce the no-load and load losses of transformers, with extremely high efficiency. For enterprises pursuing the “dual carbon” goal, using high-efficiency and energy-saving dry-type transformers is an effective way to reduce carbon emissions.

3.Key application areas: Where is it most needed?

The characteristics of dry-type transformers determine that they are almost irreplaceable in the following fields:
Commercial and public buildings: serving as the power distribution core of the building, ensuring overall electrical safety.

• Data center: The power demand for servers in data centers is enormous and must be guaranteed to be absolutely reliable. The high safety and ability to be installed close to the load of dry-type transformers make them an ideal choice.
• Industrial manufacturing: Dry type transformers can operate stably in flammable, explosive, or harsh environments such as chemical and mining industries.
• New energy: It is also widely used in solar and wind power plants to boost and grid the electricity generated by generators.

In summary, dry-type transformers have become the backbone of modern distribution systems due to their comprehensive advantages of safety, environmental protection, energy conservation, and easy maintenance. With the acceleration of urbanization and the vigorous development of the digital economy, its importance will only increase day by day.
