Gas discharge tube (GDT) arresters are widely used protection devices which function as surge protectors and are critical components in power transmission systems and other equipment. GDT arresters provide protection to both the facility and its components from damaging electrical surges, lightning strikes, overvoltages, and other potential hazards. GDT arresters consist of a series of electrical components, including a spark gap, zener diode, power resistor, and a gas-filled tube. The arresters are installed at the vulnerable point where the surges can enter the system, and when triggered, they provide a path to ground for excess electrical energy.

The 2039-80-ALF series of GDT arrester is specifically designed for very heavy duty applications requiring a high degree of lightning protection and overvoltage protection. This particular series offers excellent performance and enhanced surge protection capabilities in the region of 30kA, making it ideal for medium-voltage power transmission systems. The 2039-80-ALF series of GDT arresters are constructed with a modular design that allows for multiple interlocking units to provide greater protection, and they are capable of withstanding high voltage and surge currents with superior long-term durability.

The working principle of the GDT arrester is based on the concept of an electron cascade effect. When the arrester is mounted on a grounded system, current flows from the arrester into the ground. However, if a higher than normal electrical surge or voltage occurs, it forces electrons within the GDT to become excited and flow in the opposite direction. This electron cascade effect reduces the voltage going into the ground and dissipates the energy, thus preventing damage to the system. The spark gap within the GDT is activated by a triggering voltage, allowing the higher voltage to flow safely into the ground. The power resistor serves as a stabilizing component, ensuring consistent operation of the GDT by preventing the flow of excess current.

The 2039-80-ALF series of GDT is designed for use in critical power transmission systems, offering superior protection from surges and lightning. Such systems can include substations, power lines, lightning protection networks, communication networks, and other high voltage applications. These arresters are particularly well suited for use in areas where lightning is a common occurrence, as their superior construction and modular design ensures reliable protection. Additionally, they can be connected in series with other GDT arresters to provide multiple surge protection capabilities and enhance the overall protection of the system.

The 2039-80-ALF series of GDT are designed to provide maximum protection for power transmission systems and other equipment. They have superior surge protection capabilities and are designed for use in areas with frequent lightning strikes. With their modular design and advanced electron cascade effect, these GDT arresters are capable of providing optimal protection for even the most high-voltage applications.
