Product Overview
The model of gas surge arrestor is TD-FDN-JKY-17 6G.A gas discharge tube (GDT) is a high-voltage overvoltage protection device commonly used to absorb surge energy and discharge it to ground. Its operating principle is that under the influence of overvoltage (such as lightning surges or switching overvoltage), the gas inside becomes ionized, forming a conductive path that quickly directs the overvoltage current to ground, protecting downstream equipment from damage.
Features of GDTs:
High current handling capability: It can withstand the high currents generated by lightning surges, typically reaching tens of kiloamperes.
Low capacitance: It is suitable for circuits transmitting high-frequency signals.
High insulation resistance: It has little impact on circuit performance under normal operating conditions.
Fast response time: It is typically in the nanosecond range.
