FAQ
1. What is a gas discharge tube (GDT) used for?
GDTs are used to protect circuits from high-energy surges such as lightning strikes and transient overvoltage events.
2. How does a GDT arrester work?
A GDT operates by ionizing gas inside the tube when voltage exceeds a threshold, creating a conductive path to safely divert surge current.
3. What are the advantages of GDT compared to TVS or MOV?
GDTs handle much higher surge currents and provide better isolation, but have slower response times compared to TVS diodes.
4. Where are GDT arresters commonly used?
They are widely used in telecom lines, power systems, industrial equipment, and outdoor installations exposed to lightning risk.
5. Do you support sourcing discontinued GDT components?
Yes, we help source obsolete or hard-to-find GDT arresters and can recommend suitable alternatives.
6. What is your quality assurance policy?
All products come with a 180-day warranty. Customers must provide authorized test reports or visual evidence for any claims within the valid period.
