Customization is available, including voltage options such as 10000v, 5000v, 1140v, 690v, 660v, 600v, 480v, 460v, 415v, 440v, 400v, 380v, 360v, 315v, 220v, 208v, 200v, 127v, 110v, 100v, 48v, 36v, 24v, 12v, and 6.3v, among others. The DG single-phase dry-type isolation transformer, produced with selected materials and advanced technology over the years, boasts features like moisture resistance and easy maintenance. It can penetrate deep into load centers and is primarily used for control power and power supply in various electrical equipment across industries such as high and low-voltage electrical systems, import and export equipment, precision machine tools, UPS systems, electroplating, lighting, heating, communication, and chemical engineering. It is widely used in places such as subways, high-rise buildings, airports, stations, ports, industrial and mining enterprises, and tunnels for power transmission and distribution as well as for import and export equipment. The DG single-phase dry-type isolation transformer is mainly used in power supply locations with AC frequencies of 50-60Hz and voltages not exceeding 500V. The design and manufacture of the transformer's input and output voltages, connection groups, and tap wire group capacities can all be tailored to the customer's requirements.
