General
Toroidal transformer is a large type of electronic transformers, has been widely used in home appliances and other technical requirements of higher electronic equipment, its main purpose is as a power transformer and isolation transformer. Ring transformer in foreign countries have a complete series, widely used in computers, medical equipment, telecommunications, equipment and lighting, and so on. China’s ring transformer in recent years from scratch, has so far formed a considerable scale of production, in addition to meet domestic demand, but also a large number of exports. China is mainly used for home appliances and audio equipment and automatic control equipment, and quartz lighting and so on. Small vibration noise The core does not have the air gap can reduce the iron core to induce the vibration noise, the winding evenly wraps tightly the annular core, effectively reduces the magneto striction to cause “buzzing” the sound. Low operating temperature As the iron loss can be MW 1 kg, iron loss is very small, core temperature is low, the windings in the lower temperature of the core cooling in good condition, so the transformer temperature-is-low.

Product Description
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 transformer, 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 long life. Copper is better and also higher price. For relay type transformer, we use toroidal 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’s totally not a problem. We can prepare relative documents to foreign affairs office or other offices 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’s absolutely no problem to do OEM. But if you use our logo ZX, it 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 in North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid
East, Eastern Asia, Western Europe and so on. Some of them are our regular customers and some of them are developing. We hope you can join us and make mutual benefits from our cooperation.
