Gas Discharge Tube Arresters (GDT) come in many shapes and sizes with a wide range of applications. One of these is CG5145 which is a gas-filled tube that can help prevent damage caused by over-voltage spikes. This particular type of GDT is used primarily as a surge protection device in low voltage systems. It is typically used in combination with other surge protection components such as lightning arresters, and fuses.

CG5145 arrester is utilized in a direct lightning strike or an AC power fault line, as well as other sensitive equipment system applications, such as communication, data and control systems. This GDT is designed to be used in electrical systems with an operating voltage of up to 600 V. This type of arrester provides superior protection against power surges, transients, and lightning strikes.

The design of the CG5145 arrester consists of a small tube filled with an inert special gas mixture. This mixture contains a combination of Neon, Argon, and Mercury vapor. During normal operation, the gas-filled tube acts as an insulator. When the operating voltage of the system increases to above the specified level, the tube becomes charged, which causes an electric arc between the electrodes of the tube. This arc serves to break the flow of the electricity and stop the surge.

The own working principle of the arrester aside from the design of its construction is to limit the potential and therefore, maximize the protection of the system. This conductive mechanism limits the short circuit energy and keeps it under control. This process acts fast and effective in keeping the system safe. By absorbing the peak excess potential of an over-voltage spike, CG5145 arrester keeps the electrical system from experiencing permanent or long-term damage.

The CG5145 arrester is typically installed in a series in the power cable or at the meter box before it reaches sensitive downstream equipment. It is also recommended to install protective devices on each side of the arrester in order to make sure the arrester is functioning correctly. It is important to remember that the arrester only provides protection in one direction. Therefore, it is essential to ensure that it is installed correctly in the circuit in order to achieve the desired protection.

Overall, the CG5145 arrester is an excellent choice for any application that needs surge protection, particularly in low voltage systems. Not only does it offer superior protection, but it also helps to keep the system operating accurately, quickly and reliably. This type of GDT is simple to install and maintain and provides protection from damaging power surges and lightning strikes.
