1. Dry-type power transformer can avoid the danger of fire and explosion of transformer oil caused by faults in operation. Because the insulation materials of dry-type transformer are all non-flammable materials, even if the transformer fails in operation and causes fire or external fire sources, the fire disaster will not be expanded.
2. Dry-type power transformers do not have oil leakage problems like oil-immersed transformers, and there are no transformer oil aging problems. Usually, the workload of operation, maintenance and repair of dry-type power transformers is greatly reduced, and even maintenance-free.
3. Dry-type power transformers are generally indoor devices, which can also be made outdoor for places with special requirements. They can be installed in the same room as switchgear cabinets to reduce installation area.
4. Dry-type power transformer has few accessories because of no oil, no oil storage cabinet, safe airway and a large number of valves, no sealing and other problems.
