Gas Discharge Tube Arresters (GDT) bring safety and stability to circuit systems. Originally designed as lightning surge protectors, GDT now serves a much wider range of applications. The 2026-42-A GDT is particularly useful in suppression systems that handle high-voltage pulses, and it contains a preset upper working voltage limit to protect sensitive circuits.

The 2026-42-A GDT is composed of two main elements–a metal oxide valve and a gas-filled tube–that work together to cultivate highly reliable overvoltage protection. The metal oxide valve is made up of several electrodes in a chamber filled with metal oxides and a non-flammable gas. Together, these materials serve to control the flow of electrons and prevent the flow of destructive sparks or noisy fluctuations.

The gas-filled tube is comprised of one or more tubes filled with a precise amount of gas, typically sulfur or carbon hexafluoride, with predetermined electrode gaps. This is done so to ensure optimal attenuation from the electron current passing through the tube. The gases used in the tubes have a high dielectric strength, meaning a very high relative permittivity, enabling them to withstand extreme voltages without losing capacity.

The combination of the metal oxide valve and the gas-filled tube provides excellent protection from transient overvoltages. When presented with a high AC or DC voltage, the 2026-42-A GDT will absorb its capacity and conduct it safely to the ground. This safeguards your equipment from the destructive power of spikes, surges, and thermal stress.

In addition to its protection capabilities, the 2026-42-A GDT features low residual voltage capacity, low leakage current, and high efficiency. This makes it ideal for power application systems that are sensitive to even the slightest of electrical disturbances. It also boasts excellent de-energization performance and lightning current protection.

What sets the 2026-42-A GDT apart from other GDTs is its ability to operate at higher voltages and frequencies than its competitors. The 2026-42-A GDT operates at a maximum frequency of 500 Hz, almost double the usual rate of 250 Hz. This makes it well-suited for applications where high-frequency signals are encountered regularly, such as telecommunications and military systems.

The 2026-42-A GDT is also suitable for areas prone to power outages and it can be used in a wide range of AC/DC circuits. It is particularly useful for high-power applications, such as the recovering of electrical energy from AC/DC inverters and motors. In such circuits, the 2026-42-A GDT can reduce the likelihood of electric shock or spark generation, enhancing the safety of your system.

Overall, the 2026-42-A GDT is an excellent choice for reliably protecting power systems from hot switching, overvoltage, and other electrical disturbances. Its combination of advanced features, such as its high-frequency operation and low residual voltage capacity, make it the perfect choice for any application where enhanced electrical protection is needed.
