Gas Discharge Tube Arresters (GDT) is a type of arrester which is designed to provide protection to electrical systems against overvoltage caused by atmospheric disturbances. The GDT, also known as spark gap, is a voltage-limiting device used in electrical circuits to protect against electrical transients and surges.

The 2026-20-C2F arrester is a GDT-based surge arrester. It is designed for protection against high-voltage power spikes generated by lightning strikes and other sources of power disturbances. It features a 150V, 20kA MOVarrestor, which provides overvoltage clamping and surge current limiting, and a linear discharge tube which dissipates a large voltage spike before it reaches the protected equipment.

The 2026-20-C2F arrester is most commonly used in telecommunications, data processing, and medical equipment applications, as well as industrial applications where high-level surge protection is required. It is used in systems where power spikes may be caused by lightning, power surges, or electrical noise.

The working principle of the 2026-20-C2F arrester is based on the conduction of the MOVarrestor. When a surge occurs, the MOVarrestor is activated, which causes the current to flow through the MOVarrestor and through the discharge tube. The current is limited by the MOVarrestor and the voltage is limited by the linear discharge tube. As the surge is dissipated by the MOVarrestor and the discharge tube, the voltage is reduced to prevent damage to sensitive equipment.

In summary, the 2026-20-C2F arrester is a type of GDTbased surge arrester which provides overvoltage protection to sensitive equipment. It is most commonly used in data processing, medical, industrial, and telecommunications applications, where it is able to protect equipment from high-voltage power spikes. The arrester works by allowing current to flow through the MOVarrestor and discharge tube, where it is dissipated and the voltage is reduced.
