Gas discharge tube arresters (GDT) are electric protection devices that are installed in power systems to protect from lightning-induced over-voltages and electrical disturbances. The most common type of GDT is the metal-enameled gas surge arrestor, which is designed to protect against both transient and continuous over-voltages. GDTs are a type of overvoltage protection device that uses a gas-filled tube, usually filled with a noble gas such as argon, helium, or neon, to provide a conducting path between the two electrodes when an excessive voltage level is reached. This allows the current to be diverted away from the protected equipment and thereby preventing any damage.

The 2026-20-A gas discharge tube arrestor is a type of GDT that is designed to provide enhanced protection against both transient and continuous over-voltages. It is characterized by a long time response and a high degree of protection against undesired over-voltages, and is suitable for use in both high and low voltage applications. The 2026-20-A GDT consists of two electrodes enclosed within a gas-filled tube, typically nitrogen or an inert gas such as argon. When a voltage above a specified threshold is reached, the gas within the tube is ionized, creating a conducting path between the two electrodes.

The working principle of the 2026-20-A GDT is based on the phenomenon of electrical breakdown. In an ideal GDT, the electrodes are closely spaced and current will flow between the two electrodes when a voltage is applied. In the 2026-20-A GDT, when a voltage exceeds a certain predetermined level, the gas between the two electrodes is ionized, creating a conducting path between the two and allowing the current to be diverted away from the protected equipment.

The 2026-20-A gas discharge tube arrestor is most commonly used in various applications such as telecommunications and power systems, in both indoor and outdoor environments. In the power system application, the GDT is typically installed at the point of connection of the equipment to the system, thereby providing protection to the entire system. In the telecommunications application, it is usually installed at the interface of two equipments to protect from any transients or surges. It is also used in medical equipment, as well as in other electronic and automotive applications.

The 2026-20-A GDT provides enhanced protection against both transient and continuous over-voltages, and has a long time response. It is also characterized by a high degree of protection against undesired over-voltages, making it suitable for a wide range of applications. The 2026-20-A is designed to provide excellent protection for both high and low voltage applications, making it an ideal choice for a variety of applications.
