With the accelerated intelligent transformation of urban power grids, the proportion of 3 Phase Dry Type power distribution transformer in applications in densely populated areas has been continuously increasing due to its safety and environmental protection features. This equipment adopts solid insulation materials and air convection cooling design, fundamentally solving the problems of oil leakage pollution and fire hazards existing in oil-immersed power transformers. 

In scenarios such as commercial complexes and data centers, the oil-free advantage of dry type power transformers is particularly prominent. They can be directly embedded into the internal cabinets of buildings without the need for separate fire isolation facilities. Industry insiders point out that it complements the integrated concept of American box transformers. The former excels in indoor precision power distribution, while the latter is suitable for outdoor rapid deployment with its compact design. 

At present, in many old power grid renovation projects, 3 Phase Dry Type Power distribution transformer has gradually replaced traditional equipment. Its features of convenient maintenance and stable operation are promoting the transformation of distribution systems towards greater safety and efficiency, providing key equipment support for the construction of smart grids.
