Product Description

Product Description

Introducing the state-of-the-art non-encapsulated coil three-phase dry-type power transformer, an innovation crafted with the Nomex insulation system approved by UL. Revel in unparalleled safety and reliability, complemented by energy efficiency, fire prevention, and explosion-proof capabilities. With easy maintenance, it features an advanced design and a streamlined structure, presenting an aesthetic brilliance that surpasses domestic standards. From low partial discharge levels to minimized no-load and load losses, our transformer operates with reduced noise and thrives even in high humidity environments, making it ideal for installation in polluted and moist settings near lakes, seas, and rivers. Perfectly suited for areas demanding stringent fire protection and heavy-duty loads, such as high-rise buildings, airports, stations, wharves, subways, hospitals, power plants, metallurgical industries, shopping centers, densely populated areas, and sectors like petrochemical and nuclear power plants. The dry-type distributing transformer, encased in epoxy, remains flame retardant, explosion-proof, maintenance-free, and pollution-free, while its compact design ensures seamless integration into load centers.
