Gas Discharge Tube Arresters (GDT) are specialized components designed to protect against electrical damage from lightning, voltage surges, and other high-voltage phenomena. The SA2-5500-CLT-STD is a type of GDT designed for applications in high voltage power systems. This GDT is an advanced solution for protecting power lines and other equipment from damage. In this article, we will discuss the application field and working principle of the SA2-5500-CLT-STD.

GDTs provide enhanced protection from lightning and other threats to AC power systems and associated equipment, including sensitive electronics. This includes protection from AC power line sags and momentary outages, voltage surges generated by switching and other sources, and electrical damage due to lightning. GDTs are typically installed near key points in power systems, and are designed to absorb the entire energy of a lightning strike. The SA2-5500-CLT-STD is a series of GDTs designed for use in high-voltage power systems, such as transmission lines, distribution systems, and electronic equipment.

In terms of application field, the SA2-5500-CLT-STD is suitable for use in power systems up to 230kV. It can be used in both AC and DC systems, ensuring maximum flexibility. These GDTs can be used for both protection and fault solutions, eliminating the need for separate components. The GDTs also have a very low resistance, making them ideal for use in high-power applications. The SA2-5500-CLT-STD GDTs have a compact design and are designed for reliable performance under any conditions.

In terms of working principle, the SA2-5500-CLT-STD GDTs use a combination of gas-filled tubes and spark gaps. The spark gaps are designed to prevent high voltage pulses from reaching other components, and to prevent any arcing or sparking in the system. The GDT also includes a short capacitor, which helps to dampen out any high-frequency voltages, while the gas-filled tubes provide the insulation necessary for the GDT to function properly. When a surge or lightning strike occurs, the gas-filled tubes of the GDT are activated and the excess current is diverted away from the equipment.

The GDT includes two durable electrodes which are designed to withstand the high temperatures of a lightning strike without melting or arcing. The electrodes also improve the GDT’s energy absorption capacity and dissipate energy as heat. The GDT is also designed to operate within very tight tolerances, preventing any false triggering of the GDT. This ensures that the GDT will react quickly enough to protect the equipment from damage in the event of a surge or lightning strike.

In summary, the SA2-5500-CLT-STD is a type of Gas Discharge Tube Arresters (GDT) designed for use in high-voltage power systems. It is suitable for use in AC and DC systems up to 230kV and is designed for reliable performance. The GDT uses a combination of gas-filled tubes and spark gaps for protection against AC sags, voltage surges, and lightning strikes. The GDT also includes two durable electrodes and a short capacitor to dampen out any high-frequency voltages. This ensures that the GDT is capable of protecting power lines and other equipment from damage.
