Gas Discharge Tube Arresters (GDT) have long been used to protect electrical circuits in the transmission and distribution of electricity. The 2026-20-C2FLF is a new type of GDT that provides superior protection against lightning surges, which can cause substantial damage to electrical systems. This article provides an overview of the application field and working principle of the 2026-20-C2FLF.

GDTs are used to protect electrical systems from both high voltage and high power surges. In the case of lightning surges, the GDT acts as a buffer, redirecting the energy from the surge away from the protected system and preventing potential damage. GDTs are effective in blocking high frequency transient currents with rapid waveform shapes. In general, GDTs are composed of two main elements: the main surge element, made of a semiconductor material such as silicon dioxide, and the control element, which is typically made of carbon.

The 2026-20-C2FLF is a specialized GDT with both general and specific applications. Specifically, the 2026-20-C2FLF is used for the protection of medium and high voltage (MV/HV) outdoor electrical systems, including power distribution and communication networks. This GDT also features a fast discharge time and high impedance against sudden current changes. This allows it to effectively protect electrical systems from high lightning surges.

The working principle of the 2026-20-C2FLF is similar to other GDTs. When a predefined overvoltage is exceeded on the protected system, the internal breakdown voltage of the 2026-20-C2FLF is exceeded. This allows current to flow from the overvoltage to the GDT, reducing the voltage and protecting the system from any potential damage. At the same time, the control and current-limiting element reduces the high rate of rise of current to keep the GDT within its operating parameters.

The application field for the 2026-20-C2FLF is broad, encompassing medium and high voltage power distribution and communication networks, both indoor and outdoor. It can also be used in other industrial applications, such as photovoltaic systems and critical electronics. Additionally, the 2026-20-C2FLF is compatible with system controllers and intelligent electricity networks.

In summary, the 2026-20-C2FLF is a specialized GDT that provides superior protection against both high voltage and high power surges, including lightning surges. It has a wide application field, including power distribution and communication networks, and is compatible with system controllers and intelligent networks. Its working principle is similar to other GDTs, and involves the use of a main surge element and a control element that limits the current and reduces the voltage to safe operating levels.
