Gas Discharge Tube Arresters (GDT) are one of the essential components of a surge protection device. They are used in a variety of applications to protect devices in industrial and communications systems from lightning strikes, electrical surges, and other forms of transient energy. GDTs are also used in surge protection circuits to protect equipment from high-voltage over-loads and minor faults in power lines.

Among these GDT types, CG2230SN is an enhanced, medium power-grade GDT that is designed to protect sensitive electronic equipment from lightning-induced and other transient over-voltage events. CG2230SN strike voltage is 22kV, and the peak pulse current is 30kA. It has a functional temperature range between -40℃ and 85℃. Its encapsulation, ensures a reliable product performance and high mechanical strength against shock and vibration.

CG2230SN can be used in different application fields. In industry, this GDT can be used to protect valuable electrical equipment from the surges caused by lightning strikes, load switching, utility backfeeding, and lightning-induced surges. CG2230SN is especially suitable to be used in the incoming line to protector higher voltage equipment and long-term load circuits. In telecom, CG2230SN can be used in the protection of communication base stations, station systems, optical communication systems, and co-axial cables. In residential applications, it can be used in the protection of home appliances like washing machines, TVs, air-conditioners, microwave ovens, etc.

The working principle of CG2230SN is relatively simple. It\'s composed of two parts: the inner electrode and the outer electrode, which are sealed together in an air-tight vacuum chamber. When the voltage of protection device exceeds the surge voltage, the spark gap of the GDT will break down and cause an electric arc in the chamber. The energy released during the arc is dissipated, and the arc gap will reset itself. In this way, the protection device can be secured from the surges.

To prepare the GDT for installation, the first step is to make a hole and mount it to an adequately sized support structure in the designated location. It is important to ensure that the GDT is mounted in an upright position to ensure proper operation. Then, install the surge protection device to the GDT to protect it from the surges and lightning strikes. After this is done, the GDT is ready to be powered up.

In summary, CG2230SN is a medium power-grade GDT. It is designed to protect sensitive electronic equipment from transient over-voltage events, and has an operational temperature range of -40℃ to 85℃. It is widely used in industrial, telecom, and residential applications. Its working principles are relatively simple; when the voltage exceeds the surge voltage, the spark gap will break down and cause an electric arc, which dissipates the energy and the arc gap will reset itself. Proper installation and mounting of the GDT is crucial for its proper operation.
