Product Details
QSG transformer series
Introduction:
QSG/SG three-phase dry type isolation transformer is a new generation energy-saving power transformer developed by our factory based on international similar products and combined with China’s national conditions, from 300VA to 1600KVA, in line with international and national standards such as IEC439 and GB5226. The winding adopts the method of winding out the hole row. The transformer is vacuum-impregnated, so that the insulation grade of the transformer reaches F class or H class, and the product performance reaches the advanced level at home and abroad. QSG/SG series three phase dry type isolation transformer is widely used in circuits with AC 50Hz to 60Hz and voltage below 2000V. all can be specially customized as per different requirements of the end users.
Symbol meanning:
Normally Use Condition:
1.The altitude not exceed 2500M
2.Ambient medium temperature: ≥-25℃,≤+40℃.
3.The current and voltage waveform is similar to a sine wave.
4.No snow and rain erosion and the installation place without significant shaking and shock vibration.
5.No explosion danger, no gas and conductive dust.
6.Input and output voltage can be customized according to customer needs.
Technical Parameters:
QSG is autotransformer type ,SG is Isolation transformer type .
Appearance is same .the different is SG have more fuction such as protection .

Q 1. what's the payment term?
A. We accept TT,30% deposit and 70% balance against copy of BL.
Q 2. how's the delivery time ?
A. usually it will take about 7-20 days for production. For sample usually in 1 week.
Q 3. Tell me the standard of package?
A. For the small capacity, color box as inner package and carton as delivery package. For big capacity, use strong wooden case for protection.
Q 4. What kind of material of transformer?
A. For servo type stabilizer, we have two types, one 100% copper and the other is copper with aluminum. It depends on your requirement . In fact, those two have no difference if normal work well. Only except the longlife. Copper is better and also higher price. For relay type stabilizer,we use toroid coils, the material is aluminum. comparing with square coils, toroidal coils with high efficiency.
Q 5.Could you offer Form A or C/O ?
A. It totally not a problem. We can prepare relative documents to forgin affairs office or other office to apply for this certificate.
Q 6.Would you accept to use our logo ?
A.Our logo is ZX. If your order,has good quantity,
it absolutly no problem to do OEM.
But you use our logo ZX will be high appreciated.
Q 7.We want to know month capacity.
A. It depends on which model.For example for relay type small capacity , month capacity can reach near 10000pcs and big capacity near 2000pcs.
Q 8.Where is your market?
A. Our products are popular inNorth America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western Europeand so on.Some of them are our regular customers and some of them are developing. We hope you can join us and make mutural benifit from our cooperation.
Q 9. what kind of certificate you have ?
A. Our company already obtained CE , ISO9001,PCT,SGS. d
