Gas Discharge Tube Arresters (GDT) are a critical component in a variety of applications, including power protection, lightning protection, surge protection and signal protection. CG5145L is a GDT specifically designed to meet the stringent requirements of modern industrial and communications applications. In this article, we will discuss the application fields and working principles of CG5145L.

Application Fields of CG5145L

CG5145L is primarily used in industrial and communication systems for surge and overvoltage protection, as well as for signal protection. Specifically, CG5145L can be used to protect circuits from high pulse currents and voltage surges, high DC and AC voltages, radio frequency interference (RFI), and electrostatic discharge (ESD). Additionally, CG5145L can be used for personnel protection from electric shock or unwanted electrical power.

Working Principle of CG5145L

CG5145L is a type of Gas Discharge Tube Arrester (GDT) that utilizes a nonlinear breakdown voltage characteristic to protect system components from electrical surges. The CG5145L utilizes a special gas mixture in order to achieve its desired nonlinear breakdown characteristics. When subjected to an electric field, the gas inside the GDT ionizes and creates a shield of current carriers, mainly electrons and photons, that absorb the incoming surplus energy. This energy is then dissipated, while the protected circuit remains unharmed.

For consistent and reliable protection, CG5145L’s cutoff voltage and breakdown voltage must be carefully matched to its application. The cutoff voltage ensures that normal operating voltages do not cause the GDT to switch on, while the breakdown voltage must protect the circuit from sudden voltage surges. The nonlinear properties of CG5145L ensure that its breakdown voltage can be precisely adjusted to any value within the required range.

Conclusion

CG5145L is a type of Gas Discharge Tube Arrester specifically designed for industrial, electrical and communication applications. Its nonlinear properties make it ideal for surge and overvoltage protection, as well as for signal protection. By matching the CG5145L\'s cutoff voltage and breakdown voltage to its application, one can achieve consistent and reliable protection.
