CG21000L

Gas Discharge Tube Arresters (GDT) are an essential part of any electrical system. By protecting equipment against lightning, surge, or other abnormal high voltage occurrences, GDTs are used to prevent major damage to equipment and to provide long-term operation and safety of systems. One of the most common GDTs used today is the CG21000L. The application fields and working principles of the CG21000L will be discussed in the following content.

The Application Fields of CG21000L

Unlike some GDTs, the CG21000L is designed for use in high-power electrical systems. This makes the CG21000L suitable for use in various power lines, such as transmission and distribution. It is also suitable for use in railway, wind power, and other high-power electrical systems. In addition, because of its excellent performance, the CG21000L can also be used in communication systems, computations, and test systems. As a result, the CG21000L is typically found in various industrial, commercial, and residential systems.

The Working Principle of CG21000L

The CG21000L is a non-linear voltage-current device. It can be used to protect systems from potential surges or abnormal high voltage events. When a voltage surge occurs, the CG21000L will act as a short-circuit device, allowing high current to flow through and dissipate. The CG21000L utilizes a ceramic tube to arc over and break the circuit quickly; this device is known as an arc quenching tube. In addition, the CG21000L also feature a built-in resistor, known as the impulse resistor. This resistor is designed to limit excessive current, thereby further protecting the electrical system.

The CG21000L is a multi-stage protector, meaning it is designed to respond to different levels of voltage and current. When the protection voltage is lower than the set level, the CG21000L will not respond. However, when the over-voltage exceeds a certain level, the CG21000L will respond quickly and break the circuit. This ensures that the device will respond to abnormal surges, but will not be tripped by normal voltage fluctuations.

In conclusion, the CG21000L is an advanced device designed for protection against voltage surges or abnormal high voltage events. It can be used in various applications fields to provide long-term protection to systems. The CG21000L utilizes multiple levels of protection and a built-in impulse resistor to provide safe and reliable operation.
