Dry-type power transformer is an important equipment used in power systems. It is made of highly magnetically permeable material, has good insulation and heat dissipation properties, and is suitable for indoor environments. The transformer uses dry insulation technology and requires no maintenance liquid coolant, reducing environmental pollution and fire risks. It can adjust the voltage to an appropriate level through the transformation ratio to achieve electrical energy conversion in power transmission and distribution systems. Dry-type power transformers have the advantages of small size, light weight, and easy installation. They can be widely used in industrial, commercial, and residential fields to provide reliable support for the stable operation of power systems.
