Single-phase isolation transformer, 380V to 220V
Huatong (Beijing) Transformer Co., Ltd. is a professional manufacturer integrating R&D, production, and sales of power transformers, dry-type transformers, voltage regulators, reactors, and special transformers. The company has passed the ISO9001-2008 quality system certification and implements the national three-package policy for all products. Customers can enjoy free returns or exchanges for any quality issues within the warranty period, ensuring peace of mind in purchasing and safe usage. Custom orders are available (including voltage). We can produce special voltages 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 is produced using selected materials and advanced technology over many years, featuring moisture resistance and easy maintenance. It can be deeply integrated into load centers and is mainly used for control power and power supply in various electrical equipment, import and export equipment, precision machine tools, UPS systems, electroplating, lighting, heating, communication, and chemical industries. It is widely used in places such as subways, high-rise buildings, airports, stations, docks, industrial and mining enterprises, and tunnels for power transmission and distribution, as well as the use of import and export equipment. The DG single-phase dry-type isolation transformer is mainly used in power supply sites with AC frequencies of 50-60Hz and voltages not exceeding 500V. The input and output voltages, connection groups, and tap line group capacities of the product can all be carefully designed and manufactured according to customer requirements.
