![]() ![]() ![]() ![]() It is difficult to effectively suppress the lightning wave with a large rise in the wave head. The main disadvantage of the discharge tube protection characteristics is that the discharge delay is large, and the operation sensitivity is not ideal. Due to the large inter-electrode insulation resistance of the discharge tube, the parasitic capacitance is small The lightning protection of signal lines has clear advantages. Discharge tubes are often used in the first or first two levels of multi-level protection circuits, which play the role of discharging lightning instantaneous overcurrent and limiting overvoltage. It has been widely used in lightning protection of communication systems. The gas discharge tube is a gap type lightning protection component. The gas discharge tube is a gap type lightning protection element, which is used in the lightning protection of the communication system. There are two or more electrodes in the tube, which are filled with a certain amount of inert gas. Gas discharge tube refers to a type of lightning protection tube or antenna switch tube for overvoltage protection. ![]()
