Gas Discharge Tube Arresters (GDT) are an important type of surge protection technology used in many electrical systems across a variety of industries. These devices are designed to protect circuits from surges in power, which can cause permanent damage to delicate electrical components. A GDT is composed of two basic parts – the anode and the cathode, both made of metal. A conductive gas is contained within the tube, which allows for the arrester to let small amounts of current pass through without damaging the electrical system, while stopping any large surges or spikes in power.

The 2026-23-A GDT is an exceptionally reliable, highly effective surge arrester designed for applications in harsh industrial environments, such as those found in petrochemical facilities. It is capable of handling surges in voltage of up to 6kV of 750A without degrading or burning out. The arrester is designed to disconnect automatically to protect the system from any further damage in the event of a surge or spike in voltage. The device is also designed to be self-healing, allowing for any sparks or arcs between the anode and cathode to be extinguished in a controlled manner.

In operation, the 2026-23-A GDT acts as a voltage regulator, providing consistent voltage output despite fluctuations in input voltage. When the input voltage rises above normal levels, a gas discharge tube begins to conduct current, limiting the peak voltage at the output. This is done by transferring the energy in the voltage surge into a spark in the gas tube, which suppresses the surge before it can reach the working circuit. The current is then directed to the cathode, completing the “discharge” and restoring the circuit to normal.

The 2026-23-A GDT is a reliable and highly effective surge protection device that can handle high levels of surge and spike protection without any loss in performance. The device is easy to install, and its self-healing and self-disconnecting features make it ideal for applications such as those found in petrochemical plants. By limiting the peak voltage at the output, the GDT also reduces the risk of damage to circuit components by preventing any high-powered surges from reaching them in the first place.
