Our Advantages

Product 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.

FAQ

Q: Where is your market?

A: Our products are popular inNorth America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, EasternAsia, 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: What's the materials? 

A: For servo type stabilizer,we have two types, one 100% copper and the other is copper with aluminum.It depends on your require. In fact,those two have no difference if normal work well. Only except the longlife. Copper is better and also higer price. For relay type stabilizer,we use toroid coils, the material is aluminum. Comparing with square coils, toriod coils with high efficiency.

For transformer,Aluminum or Copper material is accorsing your demind.

 

Q: What's your month capacity?

A: It depends on which model. For example for relay type small capacity , month capacity can reach near 5000pcs and big capacity near 1000pcs.
