The non-encapsulated coil three-phase dry-type power transformer, crafted with the world-renowned Nomex insulation system approved by UL, offers a plethora of unmatched advantages. Emphasizing safety and reliability, it is also designed for energy conservation, fire prevention, and explosion-proof capabilities, coupled with straightforward maintenance. This masterpiece boasts an advanced design and a rational structure with an aesthetic appeal, surpassing domestic standards in key performance metrics such as partial discharge levels, no-load loss, load loss, and noise management. Uniquely adaptable to high humidity environments, it can be seamlessly installed in polluted and moisture-rich locations near lakes, seas, and rivers, and in areas demanding high fire protection and substantial load capacity. Its versatility makes it ideal for high-rise buildings, bustling airports, busy stations, strategic wharves, expansive subways, vital hospitals, powerful plants, metallurgical industries, vibrant shopping centers, densely populated urban areas, and specialized fields like petrochemical and nuclear power plants. The dry-type distributing transformer, with its epoxy-sealed winding, ensures flame retardancy, explosion-proof qualities, and maintenance-free operation, all while being pollution-free. Its compact design allows it to penetrate deep into load centers efficiently.
