FAQ
- Q: I’m interested in your current transformers. Can we start from a small order?
- A: Yes, we accept trail orders of small quantity. We fully understand the risk to shift to a new supplier.
- Q: Can you deliver some samples for test?
- A: No problem. We always provide free samples to our customers, but the express fee will be paid by receivers.
- Q: Why cannot find the current transformers I wanted in your website?
- A: Considering the loading time, we only presented a few popular current transformers in our webpages. Please tell us the parameters you wanted, and we’ll select some suitable ones from our products database for you. We can also design some new ones according to your drawing and specification.
- Q: What is your terms of payment?
- A: We accept T/T, L/C. For trial orders, we also accept Western Union, Paypal.
- Q: Do you test each piece of the current transformers before delivery?
- A: Yes, we have 100% test of critical parameters, such as current error, truns ratio error, phase shift error and so on.
