Gas discharge tube arresters (GDT) are devices used to protect electrical and electronic systems from hazardous effects caused by lightning pulses, electric fault overvoltage, or power system switching. The first application of GDTs occurred in 1879 when Lucien Gaulard installed them in an early transmission line. Since then, GDTs have become a mainstay in the electrical utility industry, providing reliable and cost effective overvoltage protection.The 2036-20-B3FLF gas discharge tube arrester is designed for use in medium voltage applications up to 36kV. It is constructed with a single stage of zinc oxide varistor blocks in an aluminium housing which is sealed with a rubber compound. The 2036-20-B3FLF has an impulse rating of 50kV per normal wave, and a continuous operating voltage of 36kV. It offers excellent overvoltage protection in medium voltage applications, such as switching and switching, lightning strikes, and electrical fault overvoltages.The working principle of a GDT is based on the discharge of electrical current through a gas medium. The gas within the GDT absorbs the energy of an overvoltage and conducts it to the ground for protection. The current in the GDT is limited by an external resistor and capacitor. When an overvoltage occurs, the capacitor and resistor combine to form a low impedance path, allowing a high peak current to flow through the GDT. This causes the internal gas to ionize and become a conducting medium. The current then passes to ground, providing the necessary protection.The 2036-20-B3FLF has an 8-hour thermal stability against lightning strikes. This means that the arrester still provides reliable protection against lightning pulses even after 8 hours of continuous operation. The device also offers excellent surge current discharge capabilities and can suppress voltage transients up to 6kV.The 2036-20-B3FLF is suitable for use in a wide range of applications, including industrial and commercial sites, and substation equipment protection. It is designed for easy installation and can be mounted horizontally or vertically. The GDT also features a long service life and offers an economical solution for protecting sensitive equipment from lightning and other overvoltage sources.In summary, the 2036-20-B3FLF gas discharge tube arrester is an ideal choice for medium voltage protection applications. It offers reliable overvoltage protection, thermal stability against lightning pulses, and excellent surge current discharge capabilities. With an economical design and easy installation, the 2036-20-B3FLF is an excellent choice for protecting sensitive equipment from various electrical hazards.
