Product Description


Introducing the cutting-edge, non-encapsulated coil three-phase dry-type power transformer, meticulously crafted with the superior Nomex insulation system, proudly approved by UL. This transformer stands as a testament to safety, unwavering reliability, and exceptional energy efficiency. Embracing fire prevention and explosion-proof capabilities, it promises hassle-free maintenance. Its state-of-the-art design, coupled with a thoughtfully structured and aesthetically pleasing build, make it stand out. The main performance metrics surpass domestic benchmarks across categories like partial discharge level, no-load loss, load loss, and acoustic noise. This resilient transformer thrives in high-humidity surroundings, making it ideal for installations near lakes, seas, or rivers, and in areas demanding high fire safety standards and substantial load capacities. Perfectly suited for high-rise edifices, airports, transit stations, docks, subways, healthcare facilities, power stations, metallurgical enterprises, bustling shopping arenas, dense urban locales, petrochemical sectors, and nuclear facilities. The dry-type distribution transformer winds its way securely with epoxy sealing, ensuring it is flame retardant, explosion-proof, maintenance-free, and devoid of pollution. Its compact form allows it to penetrate deep into load centers with ease.
