Gas Discharge Tube Arresters (GDTs) play a very important role in protecting electrical equipment from catastrophic electrical discharges. GDTs are often used when lightning strikes or overvoltage surges are anticipated. The SA2-5500-CBB-STD is a GDT which is commonly used to protect electrical systems and components. In this article, we will discuss the application field and working principle of the SA2-5500-CBB-STD.

The SA2-5500-CBB-STD is suitable for use in power systems or telecommunication lines where overvoltages caused by lightning or other phenomena are expected. It is designed for use in AC 50~60Hz power systems. It has a rated voltage of up to 5500V, and can operate continuously at 2200V. It can surge withstand a peak voltage of 10kV, and can withstand the continuous open circuit power frequency voltage of 2500V, with a voltage of 25kV and a short-time overload current of 2kA, which can effectively protect the equipment connected to the power system from damage caused by overvoltage.

The working principle of the SA2-5500-CBB-STD is based on the gas discharge tube effect. When an overvoltage occurs, the built-in protector is connected and the voltage is reduced. At the same time, due to the discharge of high electric field strength, an ionized gas discharge tube is formed. The current of the discharge tube is determined by the environment and the material used in the protector, and a gap is formed between the anode and the cathode, with the anode and the cathode being disconnected. This gap is the spark gap, and when the current reaches a certain range, the spark in the gap passes away, thus preventing damage to other corona triggered devices or components.

The SA2-5500-CBB-STD has a number of advantages compared to other GDTs. It has a very high breakdown voltage, which is much higher than that of other GDTs, allowing it to effectively protect against higher voltages. It is more reliable than other GDTs and has a long life, with a service life of up to 40 years. In addition, it has a very low failure rate and is able to handle high surge currents. It is also very small and lightweight, making it easy to install and maintain.

The SA2-5500-CBB-STD is a versatile and reliable GDT which can be used in a variety of applications. It is suitable for use in power systems where overvoltage is a concern, such as in lightning-prone areas. It is also useful for protecting several pieces of equipment from damage due to overvoltage, due to its high breakdown voltage and surge current handling capability. Finally, it has a long service life, making it a cost-effective solution for protecting electrical systems and components.
