Gas Discharge Tube Arresters (GDT)—also known as spark gap arrestors, gas arrestors, pulse limiters, spark suppressors, or voltage limiters—are voltage-sensitive devices used to protect electrical circuits and equipment from damage caused by lightning surges and unexpected power line faults. Different designs are available for different voltage ranges and applications.

The 2026-25-C2FLF arrester is used as an overvoltage protective device for coaxial and waveguide systems in critical applications in land, sea, and airborne applications. This arrestor is designed to limit the peak impulse voltage from lightning, nuclear electromagnetic pulses, and other sources of high voltage transients.

The 2026-25-C2FLF arrester features a ruggedized aluminum housing and is suitable for use in the most demanding environmental conditions. The 2026-25-C2FLF arrestor is designed to provide superior protection from damaging electrical transients. It can be used in telecommunications and radar systems, antenna protection, satellite communication systems and high-frequency data and signal transmission circuits.

The working principle of the 2026-25-C2FLF arrester is based on a Gas Discharge Tube (GDT) that is filled with a gas mixture of nitrogen and argon. When the voltage applied to the arrester exceeds a predetermined level, the gas mixture in the GDT ionizes, forming a conducting path. This conducting path limits the voltage to a safe level, and the current is dissipated as heat. Once the voltage is reduced to a safe level, the conducting path is broken and the GDT returns to its non-conducting state. This allows the arrester to reset itself and be ready for the next surge.

The 2026-25-C2FLF arrester’s design also includes a varistor element that provides additional protection from lightning and other transient voltage events. The varistor element has a high peak surge current rating and helps to ensure that no current flows to the system when no voltage is present. The combination of the GDT and varistor elements ensures a reliable, accurate, and maintainable surge protection system.

The 2026-25-C2FLF arrester provides superior protection to telecommunications and radar systems, antenna protection, satellite communication systems and high-frequency data and signal transmission circuits from electrical transients. It is ruggedized to ensure reliable operation in demanding environments and can be used in operating temperatures from -40°C to +70°C. The 2026-25-C2FLF arrestor offers reliable power line protection with an outstanding performance to price ratio.
