Gas Discharge Tube Arresters (GDT)
Gas Discharge Tube Arresters (GDT) are a common form of electrical protection device that uses a Gas Discharge Tube (GDT) to provide a physical barrier to high-voltage spikes and other disturbances in the electrical current. The CG7120MS is a GDT arrestor specifically design for Telecommunications applications.
Application Field
The GDT arrester was initially designed for the Telecommunications industry. It is used to protect against high-power spikes in the electrical current, generally caused by lightning strikes, during outdoor activities. It is also used to prevent damage to electrical equipment as well as the physical structure of its surroundings. As such, it is especially useful in industries involving communications, such as broadcasting, telecommunications, and IT.
Working Principle
The CG7120MS arrester works by utilizing a metallic gas discharge tube. This gas discharge tube, commonly a ceramic tube filled with gas, acts as a shield to protect against the damaging electrical current. When an electric discharge is detected, an electric current flows through the tube, releasing a large amount of energy in the form of a spark. This spark is designed to break the electrical circuit and protect the equipment from further damage. The GDT arrestor also adds a layer of insulation, allowing for a safe and effective electrical system.
Conclusion
The CG7120MS is a specialized GDT arrester designed for Telecommunications applications and other electrical systems. It acts as a shield to protect against high-voltage spikes and other electrical disturbances. By utilizing a metallic gas discharge tube, it ensures safe and effective protection of equipment against electrical malfunctions and damage. With its ease of implementation and reliable protective capabilities, the CG7120MS arrester is a great choice for various sectors where electrical safety is essential.
