Gas Discharge Tube Arresters (GDT)

Gas Discharge Tubes (GDT) also known as “surge arresters” are an important component of power systems used to protect sensitive electronics from lightning strikes and power surges. The 2028-42-C2FLF is a GDT specifically designed for applications requiring extreme levels of reliability.

Principle of Operation

GDTs work by diverting the flow of electricity away from the protected components in the following way. When a surge appears on the system, the GDT is triggered and the voltage on its electrodes increases significantly, resulting in the flow of a short pulse of current. This strobe effect temporarily ionizes the noble gas inside the discharge tube, thus creating a channel of conductivity. This effect is called a “primary flashover”.Once the voltage on the electrodes reaches a certain level, known as the “breakover voltage”, a second flashover occurs in the opposite direction, known as a “secondary flashover.” This secondary flashover reduces the voltage back to a safe level and thus prevents any major damage to the system.

2028-42-C2FLF Application Field

The 2028-42-C2FLF GDT is primarily designed for applications where extreme levels of reliability are required, such as for power line networks in highly populated areas. It’s also reliable enough for use in areas with a high risk of lightning strikes and other power surges.Furthermore, this type of GDT has the added benefit of being able to be mounted in a variety of positions, making it even more versatile. Additionally, the 2028-42-C2FLF GDT can handle up to 2,200 Joules of energy, making it extremely durable and reliable.

Conclusion

The 2028-42-C2FLF GDT is a reliable and effective component for protecting sensitive electronics from power surges and lightning strikes. Its reliable design, ability to be mounted in a variety of positions, and extremely high energy-handling capabilities make it the ideal choice for applications in which extreme levels of safety and reliability are necessary.
