Frequently Asked Questions

Q1: How to select the appropriate surge protector?

The grading of surge protectors is assessed according to IEC61024 subdivision lightning protection theory, installed at zone junctions. Technical requirements and functions differ: first-stage devices (0-1 zone) require high current capacity (minimum 25kA 10/350), while second and third stages (1-2 and 2-3 zones) primarily suppress overvoltage.

Q2: Are you a manufacturer or trading company?

We are a professional lightning surge protectors manufacturer with our own production facilities.

Q3: What is your warranty and service policy?

We provide a 5-year warranty on all products. All surge protection devices and accessories undergo triple testing before shipment. Our dedicated after-sales service team ensures prompt resolution of any issues.

Q4: Can I get samples?

Samples are available upon request. Please contact our sales team with your detailed contact information. We maintain strict confidentiality of all customer information.

Q5: Are samples free?

Samples are available but require payment. The sample cost will be refunded upon subsequent order placement.

Q6: Do you accept customized orders?

Yes, we accept customized orders and can produce according to your specific requirements.
