In the realm of electrical power systems, the three-phase oil-immersed transformer stands as a cornerstone of efficient and reliable energy distribution.The three-phase oil-immersed transformer is a marvel of engineering design. It is primarily used to step - up or step - down voltages in three - phase electrical systems. This is crucial for the transmission and distribution of electricity over long distances. By adjusting the voltage levels, it enables power to be efficiently transferred from power plants to substations and finally to end - users.

One of the key features of this transformer is the use of oil as an insulating and cooling medium. The oil not only provides excellent electrical insulation but also helps in dissipating the heat generated during the transformation process. This is vital as the transformer operates continuously, and any overheating could lead to reduced efficiency and potential damage. The oil - immersed design allows for a more stable and reliable operation, even under high - load conditions.

These transformers are known for their high efficiency. They are designed to minimize energy losses during the transformation of voltages. This efficiency is a result of precise engineering of the core and windings. The magnetic core is made from high - quality magnetic materials that help in reducing core losses, while the windings are carefully constructed to optimize the transfer of electrical energy.

In terms of construction, three-phase oil-immersed transformers are built to be robust and durable. The tank that houses the core and windings is made from strong metal alloys that can withstand various environmental conditions. This makes them suitable for both indoor and outdoor installations, from industrial plants to power substations in different climates.

Safety is also a top priority in the design of these transformers. The oil - filled tank is equipped with safety features such as pressure - relief valves. These valves prevent the build - up of excessive pressure inside the tank, which could otherwise lead to dangerous situations like tank rupture. Additionally, proper grounding and insulation measures are implemented to ensure the safety of personnel working around the transformer.

The three-phase oil-immersed transformer also offers flexibility in terms of capacity. They are available in a wide range of power ratings, from small - scale applications in commercial buildings to large - scale power distribution in industrial complexes and power grids. This adaptability makes them an ideal choice for different electrical power requirements.

As the demand for reliable and efficient electrical power continues to grow, the Three-phase oil-immersed transformer remains an indispensable component in the power infrastructure. Its combination of efficient voltage transformation, reliable operation, and safety features makes it a go - to solution for power distribution around the world.

The dry-type transformer is an epoxy resin cast power transformer, unique in that its iron core and windings are not immersed in insulating oil. Its cooling methods mainly include natural air cooling (AN) and forced air cooling (AF). From iron core production to resin casting and assembly, the entire process is self-made by Tiansheng. We adopt fully automated intelligent equipment for iron core production, realizing digital operation throughout the process from silicon steel sheet cutting to iron core stacking. This method results in iron cores with smaller gaps, lower losses, reduced noise, longer lifespan, and improved production efficiency and product qualification rates. Take a look at our completed iron cores; their surfaces are smooth and free of burrs, with minimal gaps.

Our casting process employs the most advanced domestic orthogonal self-flow and end-seal self-flow casting techniques, achieving fully automated intelligent operation from mixing to casting. The coils produced through this process are of excellent quality, with smooth and sleek surfaces, adding to their aesthetic appeal.
