Gas Discharge Tube Arresters (GDT) are an important component in the field of 9400520000 application. They are mainly used in systems connecting to outdoors, such as power grids and railway systems, where AC or DC voltage can be efficiently utilized and large lightning surges can be controlled effectively. As lightning strikes are unpredictable and potentially dangerous, GDT Arresters are critical to preventing harm to people, property or equipment.

GDT Arresters belong to a family of electrical equipment known as Gas Discharge Tubes (GDT). These arresters are generally made up of two components: a spark gap and a gas chamber. The spark gap, also known as a trigger, is an ionized air gap between two electrodes connected to an insulated layer of dielectric material. The dielectric layer stores a large amount of electric energy and allows the spark gap to open when a lightning surge reaches it. Once it opens, it feeds the electrical energy to the gas chamber. In the gas chamber, the energy is further dissipated through a series of controlled electrical discharges.

GDT Arresters have many advantages: they are durable, compact, require little maintenance, and are cost-effective. In addition, GDT Arresters are effective at suppressing both fast and slow-growing lightning surges. When a surge arrives, the spark gap triggers and immediately begins dissipating energy to the gas chamber. By the time the energy reaches the gas chamber, it is reduced significantly, allowing the power system to operate within normal parameters. This reduces the risk of damage to electronic equipment and makes GDT Arresters ideal for protecting sensitive electrical components.

The major applications of GDT Arresters include power grids, telecom systems, railway systems, electric/electronic systems, communication systems, industrial control systems, and other outdoor applications. These arresters provide reliable and effective protection against lightning surges, and are designed to absorb lightning energy with minimal effect on the system’s operation. GDT Arresters are also compatible with most power system components, making the installation process easier and more efficient.

GDT Arresters are designed to work automatically to protect the system when the spark gap is triggered. As soon as the lightning surge enters the system, the spark gap opens and creates an ionized air gap between the two electrodes. This triggers the GDT Arresters to activate, which then routes the majority of electrical energy to the gas chamber. Once the gas chamber has been triggered, the electrical discharge is controlled by increasing or decreasing the time that the gas chamber remains open. If the current remains steady for an extended period of time, the gap will eventually close, stopping the electrical discharge and allowing the system to resume normal operation.

GDT Arresters provide an efficient and reliable protection solution for power systems. When installed properly, they provide robust protection and can drastically reduce the risk of damage from lightning strikes. With proper maintenance and good quality components, GDT Arresters can operate for many years without any problems.
