详情描述
Our DG single-phase dry-type isolation transformers are produced over the years with premium materials and advanced technology, featuring moisture-proofing and easy maintenance. They can be deeply integrated into load centers and are primarily used for controlling power and power supply in various high and low-voltage electrical systems, import and export equipment, precision machine tools, UPS systems, electroplating, lighting, heating, communication, and chemical industry equipment. They are widely applied 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 the use of import and export equipment.
DG Single-phase Dry-type Isolation Transformers, primarily used in power supply locations with AC 50-60Hz and voltage not exceeding 500V, offer various input/output voltages, connection groups, and tap winding capacity allocations. These can all be meticulously designed and manufactured according to customer requirements.
Product Usage Conditions:
1. Environmental Temperature: -15℃ to +40℃
2. Altitude: <1000m
3. Relative Humidity: <90%
4. Installation location free from severe effects of gases, steam, chemical deposits, dust, dirt, and other explosive and corrosive media on transformer insulation.
5. Any special usage conditions not meeting the aforementioned regulations shall be determined through negotiation between the user unit and our factory.
