Q 1. what's the payment terms? Q 2. how's the delivery time ? Q 3. tell me the standard of package? wooden case for protection. Q 4. what kind of material of transformer? copper with aluminum.It depends on your requirment. 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. office or other office to apply for this certificate. Q 6.Would you accept to use our logo ? Q 7.We want to know month capacity. month capacity can reach near 10000pcs and big capacity near 2000pcs. Q 8.Where is your market? Q 9. what kind of certificate you have ? |
