Dry type transformer: the efficient choice for modern power systems

一、 Subverting the traditional technological core

The biggest feature of dry-type transformers is "dry-type" - it abandons the insulation oil of traditional oil immersed transformers and instead uses dry-type insulation technologies such as epoxy resin casting, H-grade insulation materials, or immersion insulation. Taking epoxy resin casting dry-type transformers as an example, high-purity epoxy resin is vacuum mixed and uniformly cast on the surface of the winding to form a high-strength, high insulation cured protective layer. This insulation structure not only effectively isolates air and moisture, avoiding insulation aging and oil leakage risks, but also has excellent flame retardancy and corrosion resistance, significantly improving the safety and reliability of transformers.

二、 Leading the market with five core advantages

1.Zero hidden dangers in safety and environmental protection: Oil free design fundamentally eliminates the risks of fire, explosion, and oil pollution. Even in high temperatures or short circuits, it will not produce flammable gases, making it particularly suitable for densely populated places such as shopping malls, hospitals, schools, etc.

2.Compact, lightweight, and space saving: Compared to oil immersed transformers, dry-type transformers can reduce their volume by 30% -50% and weight by 20% -40%, making them easy to install and transport. They can be flexibly embedded in building distribution rooms, saving valuable space resources.

3.Low noise, energy-saving and more economical: By optimizing the iron core structure (such as using stepped seam stacking technology) and winding design, magnetic hysteresis and eddy current losses can be reduced, and the operating noise can be controlled at 50-60 decibels.

4.Strong environmental adaptability: Using high-temperature resistant insulation materials (such as H-grade insulation, with a maximum working temperature of 180 ℃), it can operate stably in extreme environments ranging from -25 ℃ to 45 ℃. Whether in high-altitude areas or humid, dusty industrial environments, it can handle it with ease.

三、 Electricity Responsibility in Diverse Scenarios

The application scenarios of dry-type transformers are extremely wide: in urban commercial complexes, they are hidden in underground distribution rooms to provide stable power for shopping malls and office buildings; In the data center, its low loss and high reliability ensure that servers run continuously 24 hours a day; In the field of new energy, it helps wind power and photovoltaic power stations achieve voltage conversion and grid connection; In rail transit, compact design and fire resistance make it the top choice for subway and high-speed rail power supply systems.

四、 Future Trends: Intelligence and Greening

With the development of the Internet of Things and big data technology, dry-type transformers are moving towards intelligence. By integrating intelligent chips and communication modules, transformers can achieve self diagnosis, energy consumption analysis, and optimized control, becoming an important node in the smart grid. Meanwhile, driven by the "dual carbon" target, the new generation of dry-type transformers will further reduce no-load losses and noise, adopt recyclable and environmentally friendly materials, and inject new momentum into the development of green electricity.

Dry type transformers break through traditional limitations through technological innovation and provide safe, efficient, and intelligent solutions to safeguard the power supply of modern society. Whether it is current urban construction or future energy transformation, it will continue to shine and write a new chapter in the power industry.
