The Gas Discharge Tube Arresters (GDT) are a type of device that utilizes the principle of a high-voltage gas-filled arrestor in order to provide electrical protection against overvoltage. GDTs can protect against both lightning and power line surges. GDTs are typically used for voltage ranges between 10V – 40kV and are available in both single-phase and three-phase designs. When the voltage reaches a certain level, the gas inside the tube begins to ionize, forming a conducting path between the incoming and outgoing phases. This allows current to flow between the two phases, dissipating the energy of the surge. In order for GDTs to be effective, they must be designed and sized carefully.

GDTs are usually installed close to a power source and connected to the protected areas by means of a low effect impedance cable. This connection will ensure that the surge current can be quickly and efficiently discharged. Additionally, GDTs are typically installed in isolation boxes to prevent the device from being damaged by external factors such as pollutants or moisture. The 2026-25-C13 is a gas discharge tube arrester specifically designed to protect against voltage surges of up to 40kV.

2026-25-C13 is designed with three primary components: a quartz envelope, a conductive capsule, and a dielectric element. The quartz envelope serves as a barrier for the electric and thermal energy of the surge. The conductive capsule contains the gas mixture inside the quartz. When the surge voltage reaches a certain level, the gas mixture becomes ionized, forming a conductive path through the tube. This causes the surge energy to dissipate. The dielectric element is a dielectric material, typically a ceramic, which is used to further absorb and disperse the energy of the surge.

In order to be effective, the device must be properly sized and installed. The size of the device should be determined by the voltage that it is intended to protect against, typically by an analysis of the system\'s maximum surge current. The device should also be properly grounded and its its impedance must be adjusted to minimize any reflected surge. Additionally, the correct operating voltage of the device must be carefully selected in order to ensure it operates correctly.

The GDTs are designed to protect against overvoltage surges in electrical systems. They are frequently used to protect communication, power switching, and other sensitive electronic devices from overvoltage exposure. The 2026-25-C13 is a three-phase GDT specifically designed to protect systems operating at voltages up to 40kV. When properly sized and installed, the device can provide protection against high-voltage surges caused by lightning, power line surges, and other sources.

The 2026-25-C13 is typically used in industrial and commercial applications. It is ideal for power distribution systems, large-scale electrical switching applications, and any application where sensitive equipment must be protected from overvoltage surges. GDTs can also be used in residential applications, although they are typically not necessary. The device should be installed in a dry, clean environment, and it should be inspected regularly for signs of damage or aging.

In summary, the Gas Discharge Tube Arresters (GDT) are a type of device that utilizes the principle of a high-voltage gas-filled arrestor in order to provide electrical protection against overvoltage. The 2026-25-C13 is a three-phase GDT specifically designed to protect systems operating at up to 40kV. The device is primarily used in commercial and industrial applications, and it should be installed in a dry, clean environment. The device must also be carefully sized and installed in order to be effective. If properly sized and installed, the 2026-25-C13 can provide protection against high-voltage surges caused by lightning, power line surges, and other sources.
