Gas Discharge Tube Arresters (GDT) are electrical components used to protect electrical devices from surge or transient voltages that can cause damage. CG2800LS are a type of GDTs which can be applied to various fields and has a working principle to protect electrical equipment against transient voltages.

CG2800LS type holds properties suitable for mid-range energy transient applications. It is a two-element device consisting of a semiconductor section and GDT section connected in series. The GDT part offers two features: lightning surge protection and disconnector. The disconnector opens the device when the overvoltage passes the upper threshold limit of the device.

CG2800LS applies to outdoor and indoor power system or power supply where it can protect against lightning strikes, switching overvoltage, direct lightning and other transient surges. They can also be used in industries with high surge protection requirements. It can be applied in both electrical and communication systems wherever surge protection is required, such as in telephone lines, cables and switches.

CG2800LS GDTs are able to protect electrical equipment against voltage surges by redirecting the voltage surge to ground. Surge voltage is generated from lightning or other electrical disturbances, and when it reaches the surge arresters, it is redirected to ground where it is dissipated. This ensures that the electrical equipment is not damaged.

The working principle of CG2800LS GDTs is based on the concept of a spark gap rectifier. The spark gap rectifier includes two terminals connected by an air gap between them. When a sufficient voltage is applied across the gap, an electric spark occurs, causing an arc bridge across the gap. This arc bridge can either conduct or shield depending on how the device is adjusted.

When a surge signal reaches the device, the GDT works with the semiconductor element to adjust the arc bridge formation. If the surge voltage is not large enough, the GDT will form an insulation layer between the two terminals to block the surge current. If the surge voltage is large enough, the GDT will pass the surge current to ground. The passing current will be reduced by the resistance of the GDT, protecting the system from overvoltage.

CG2800LS GDTs are available in a variety of sizes and dimensions, from very small to large surge protectors. It can also be customized according to customer requirements. It also has several other features, such as excellent temperature stability, long life under normal operating conditions, low arc voltage, and low voltage interrupting capacity.

Overall, CG2800LS GDTs are reliable and efficient components that can be used to protect electrical equipment against surges or transients. They are designed to be long lasting and easy to install. They can also be customized according to customer requirements. With the right model, they can provide reliable and effective surge protection to power system or communication.
