The Gas Discharge Tube Arresters (GDT) is an overvoltage protection component that deflects high voltages. A GDT arrester is composed of a gas-filled tube, connected between two electrodes. The electrodes can be carbon rods, two metal plates or an external conductor. The gas tube can be filled with a variety of noble gases or other gases such as sulfur hexafluoride. The majority of GDTs on the market are filled with sulfur hexafluoride ( SF6 ) or nitrogen (N2).

The GDT is a protective device that functions by dissipating high voltage surges to prevent damage from lightning strikes and other overvoltage events. The GDT is installed between the system and ground so that when a surge of voltage passes through it, the gas inside the tube absorbs the energy and ionizes the gas into a plasma, redistributing the excess energy through the electrodes into the ground. The GDT can dissipate energy up to 100,000 joules for an SF6 filled tube. This effectively provides protection for systems from overvoltage.

T049217 is a special design of GDT with an electrical rating of 0.6kV - 8kV, 10kA - 20kA with a rated life of 100kA surge. The T049217 GDTeatures arc quenching technology, electrodes made of tungsten, and a hermetically sealed housing for superior protection against environmental interferences. This type of GDT can be used in the protection of cable connections, panel boards, power systems, telecommunications, CCTV, and other electronic equipment.

The working principle of the T049217 GDT is simple. When an overvoltage occurs, the current surges through the device, and through the electrodes. The electrodes ionize the air in between them, creating plasma and providing a low impedance path for the overcurrent. The plasma quickly cools, due to the Coulomb force, effectively limiting the current passing through the GDT and providing over-voltage protection. The T049217 GDT is designed to work within the voltage ranges it is rated for, and to limit the tension at which surplus electrons pass through it.

To ensure proper functioning of the GDT, it must be regularly tested and inspected. The device must also be periodically checked for cracks or corrosion which can reduce its effectiveness. Proper installation is also important to ensure that the GDT has the correct electrical unbalance required for it to function correctly. Additionally, the GDT must be mounted according to the manufacturer\'s instructions to ensure proper operation.

The T049217 GDT is a reliable and efficient overvoltage protection component, offering superior protection against lightning strikes. Its hermetically sealed housing, tungsten electrodes, and arc quenching technology help to ensure it is ready to protect equipment when needed, while its rated life of 100kA surges provides superior protection to sensitive systems. This type of GDT is ideal for use in applications such as protection of cable connections, panel boards, power systems, telecommunications, CCTV, and other electronic equipment.
