Breaking through the limitations of traditional oil-immersed transformers, the dry-type transformer uses air as the cooling medium and completely eliminates insulating oil, fundamentally eliminating the potential hazards of oil leakage, fires, and explosions, making it a representative of modern environmentally friendly power equipment. Its core components are cast using epoxy resin technology, forming a robust insulating shell that not only has excellent flame-retardant and moisture-proof properties but also effectively resists dust and moisture, adapting to various complex environments. The built-in intelligent temperature control system can monitor the winding temperature in real-time and automatically adjust the speed of the cooling fans, ensuring efficient operation of the equipment while significantly reducing operating noise and energy consumption. In addition, the dry-type transformer has a compact structure and flexible installation, requiring no special fireproof and explosion-proof facilities, thus greatly saving space and infrastructure costs. With its high level of safety, reliability, and environmental friendliness, the dry-type transformer has become the preferred power equipment for places with strict requirements for safety and cleanliness, such as high-rise buildings, precision electronics factories, and rail transit.
