Gas Discharge Tube Arresters (GDT) are a type of surge protection device designed to protect sensitive equipment from damaging transient voltages. The SL1021B350RF is one such device. In this article, we will discuss the application field, working principle and features of this particular GDT device.The SL1021B350RF is an asymmetric GDT designed for medium and medium-high voltage surge protection applications. It is typically used in the protection of power supply systems such as direct current or rectified AC systems, and can also be employed in other types of circuit protection applications. This GDT offers excellent protection against lightning-induced surge voltages and other transient voltages.The SL1021B350RF works by providing a low-impedance path to ground for overvoltages, which is created by a gas discharge tube (GDT) placed between the surge protector and ground. The GDT acts as a clamp that blocks the passage of high voltages, allowing only lower voltages to pass through. As the transient voltage reaches the GDT, the conductor material inside the GDT vaporizes rapidly, causing an electron avalanche, which allows the current to be quickly discharged to ground. The SL1021B350RF is able to keep the designed loads safe against overvoltages due to this process.In addition to providing surge protection, the SL1021B350RF also offers outstanding features. The device is encased in a robust, weatherproof ABS housing, making it suitable for outdoor use. It is also light and compact, making installation and maintenance easy. The integrated filter ensures optimum performance and improved reliability. Additionally, the GDT can withstand high temperatures up to 80°C and short-circuit currents of up to 20kA, making it suitable for a wide range of applications. Overall, the SL1021B350RF is a robust and reliable device designed for medium and medium-high voltage surge protection applications. Its outstanding features, such as its robust housing, allow it to perform reliably in a variety of demanding environments. With its exceptional performance and reliability, the SL1021B350RF is an ideal choice for surge protection applications.
