Gas Discharge Tubes protect sensitive telecom equipment.

July 27, 2004

Raychem Circuit Protection Gas Discharge Tubes (GDTs) protect telecom equipment from damage due to transient surge voltages that typically result from lightning strikes and equipment switching operations. Placed in front of and in parallel with equipment, they act as high-impedance component while not influencing signal in normal operation. In case of overvoltage surge, GDTs switch to low-impedance state to divert energy away from sensitive equipment. Read More
