Gas Discharge Tubes - 2RB-8S Series
GDT introduction:Gas discharge tubes (GDT) use noble gasses enclosed
in ceramic tubes to provide an alternate circuit path for voltage spikes.The
ceramic envelope and with nickel connectors allow for high loads and Ruilon
offers products that function at 20KA,40KA,50KA,60KA,100KA&150KA.
The breakdown voltages of the devices have a wide range (up to 20%
tolerance).Major applications are high frequency telecommunication
lines,stations, security systems,HID and high quality Surge Protection
Devices (SPD).
