Gas Discharge Tubes

We are actively engaged as manufacturer, supplier and exporter of a complete range of Gas Discharge Tubes in Shenzhen, Guangdong, China. The functions of Gas-Discharge components are effected by many parameters; such as gas type, pressure of gas and humidity etc. Especially, the pollution (particles) leads an abnormal reaction. We take a proven technique to make sure the working condition is "close and isolated: - hermetic sealing of dis-charge space.

Protection principle of GDT component:

Generally, GDT (Gas Discharge Tube) components work whenever a surge (voltage) exceed the rated-working-voltage of GDT. As the arc with high current (because of low impedence of GDT) is ignited, GDT can prevent a further rise of surge. (approximately some 10 volts)
