As core equipment in power transmission and distribution systems, transformers primarily fall into two common categories: oil-immersed transformers and dry-type transformers. These two types differ significantly in terms of structure, cooling methods, and application scenarios.

Oil-immersed transformers utilize insulating oil for heat dissipation and insulation; they are characterized by excellent heat dissipation, high overload capacity, and stable operation, making them widely suitable for power systems, industrial parks, and outdoor power supply projects.

In contrast, dry-type transformers feature coils encapsulated in epoxy resin or other insulating materials and do not require insulating oil. They offer advantages such as fire resistance, explosion resistance, and environmental friendliness, making them ideal for locations with stringent safety requirements, such as hospitals, shopping malls, data centers, and high-rise buildings.

For specific projects, customers should select the appropriate transformer type based on the installation environment, load requirements, and budget. Hebei Qishun Electric Power Equipment Co., Ltd. provides professional selection advice and customized solutions to meet customer needs.
