DG/SG
Single-phase and Three-phase Dry Type Transformer
Transformer
 
General
DG and SG series single-phase and threephase dry type transformer adopts high quality material and advanced technology, it has advantages of damp-proof and convenient maintenance, it can be applied to such power transmission and distribution places like underground railway, high building, airport, station, wharf, enterprise, tunnel, etc. It is mainly used in power supply occasions of AC 50~60Hz and voltage less than 500V. All the input and output voltage, connection group and capacity of tapped winding can be designed and produced according to users’ requirements.
 
Main Technical Data
Input voltage Rated voltage ±10%
Output voltage Rated voltgae 2-5%
Efficiceny ≥95%(power grade 50kVA above)
Waveform distortion No additional waveform distortion
Function Current, input voltage and output voltage indicators and input switch are available at request
Long-term unattended operation is allowable
Insulation resistance > 10MΩ
Electric strength Single Power frequency sine voltage 1500V for 1min without breakdown or flashover
Three Power frequency sine voltage 2000V for 1min without breakdown or flashover
 
Working Conditions
1. Ambient temperature: -15℃~+40℃
2. Altitude: < 1000m
3. Relative humidity: < 90%
4. Environment exists without gas, steam, chemical deposition, dust or dirt that will affect transformer’s insulation seriously, also explosive or corrosive medium is not allowed.
5. If any special working conditions that are not in line with the above stipulations, user shall negotiate with us.
 
Application
DG and SG series single-phase and three-phase dry type transformers are sutiable for various singlephase/three-phase AC circuits of 50~60Hz with input/output voltage 660V, used for the high-accuracy and highly sophisticated devices and electrical appliances that require to the isolated or various imported instruments and electrical devices that are out of line with the power grid voltage.
