The application fields of 2026-30-C4 and its working principles are part of Gas Discharge Tube Arresters (GDT). GDTs are used to provide protection against transient overvoltage surges from lightning or other sources on electrical and communication systems. 2026-30-C4 arrester is used as an equipment surge protector for Voltage up to 7500V, Frequency up to 69kHz and Power up to 20A. It is usually used to protect high voltage power supplies, solar inverters, electrical circuits, equipment surveillance systems, telecom communication systems, and other high-end electronic circuits.

In the working principle, the GDT consists of two electrodes separated by a gas-filled dielectric. When the voltage between the two electrodes rises above a certain level, the gas is ionized in the dielectric, forming a bridge between the electrodes conducting the current of the surge. When the voltage is reduced to below the firing voltage, the ionized gas is recombined, thus deactivating the connection between the two electrodes and cutting off the current.

The 2026-30-C4 arrester has low residual voltage and low power loss. Since the arrester\'s inner gas has the characteristics of fast response and no external influence, no permanent damage can be caused to the equipment. The electric field of the arrester decreases rapidly after the surge, so the protection effect is good.

The GDT also has a resetting pressure system. The gas pressure sensing system is composed of a diaphragm and a detection device. After the arrester extinguishes the spark, the diaphragm facing the gas chamber quickly restores its original shape, decompresses the gas chamber, and turns off the electrical conduction again to reset the arrester. The action sensitivity and speed of the resetting pressure system are greatly improved, so that the arrester can better protect the device from damage from subsequent surges.

In conclusion, the application field of 2026-30-C4 arrester is mainly in high voltage power supplies, solar inverters, electrical circuits, surveillance systems, telecom communication systems, and other high-end electronic circuits. Its principle of operation is based on the formation of an ionized bridge through the gas-filled dielectric in response to transient overvoltage surges, with rapid resetting and a low power loss. The GDT can effectively protect the connector, cable and equipment in the high-voltage system from damage due to external high-voltage impulse.
