Gas Discharge Tube Arresters (GDT) are an important class of components in the electrical safety field. They provide protection for electrical equipment, circuits, and components against electrical disturbances from lightning and switching impulse surges. This paper will explore the application field and working principle of the 2026-07-CLF GDT.

GDTs are commonly used for a variety of applications such as protection of outdoor communication devices, power control equipment, and laptops. In these applications, GDTs are typically used in combination with other components such as adjustable surge suppressors and lightning protection devices. This combination of components provides a comprehensive protection solution and is particularly effective in dispersed outdoor locations.

When setting up GDTs for protection in outdoor environments, it is important to consider several factors such as the level of transient overvoltage expected, the maximum surge impulse current capacity of the GDT, the response time and the size of the GDT. The 2026-07-CLF is a compact, single-stage GDT designed for protection against both over- and under-voltages in outdoor applications. It is designed with both over-voltage breakdown protection and undervoltage monostable protection. It is capable of withstanding up to 10 kA of lightning surge current with an 8/20μs response time. In addition, it can also withstand up to 20 kV of overvoltage and up to 10 kV of undervoltage.

The working principle of the 2026-07-CLF GDT is based on its ability to form a capacitance between the two electrodes, which, when a transient surge occurs, results in a brief current flow between them. This current flow is limited due to the capacitance created by the separate electrodes. When the current reaches a certain threshold, the GDT will discharge the stored energy, resulting in a voltage decrease that limits the surge voltage to a safe range. The GDT will then reset itself and be ready to repeat the process.

In order to ensure that the GDT can handle the level of surges expected, it is important to have the proper level of capacitance within the device. The 2026-07-CLF GDTs have adjustable capacitance values which allow the user to customize the level of protection provided by the device. Additionally, the device’s voltage limiting characteristics can be adjusted to ensure that the maximum level of surge voltage is met and do not exceed the safety levels of the equipment protected by the GDT.

The 2026-07-CLF GDTs are an effective way to protect against both overvoltages and undervoltages. Their compact size makes them suitable for use in a wide variety of applications and the adjustable capacitance values make them an excellent choice for customizing the level of protection necessary in each particular application. In addition, the fact that the device is capable of withstanding both lightning surge currents and over- and undervoltage allows for a comprehensive protection solution for outdoor applications.

In conclusion, GDTs provide a vital component for electrical safety. The 2026-07-CLF GDTs utilize a combination of adjustable capacitance, voltage limiting, and response time features to provide an effective and comprehensive protection solution for outdoor applications. Through proper utilization of the 2026-07-CLF GDTs, a broad and effective layer of protection can be achieved, keeping equipment and personnel safe from electrical disturbances.
