Gas Discharge Tube Arresters (GDT)

Gas discharge tube (GDT) arresters are most commonly used to protect electrical and electronic equipment against the effects of lightning and other fast rising voltage transients. The 2045-40-BLF is a type of GDT arrester specifically designed to provide protection against the high magnitude and energy of powerful externally-induced transients. This type of arrester is made up of an insulation housing, an insulating rod, and two terminals, which are terminated onto the system’s power supply. Inside the arrester there is an air gap which is filled with a dielectric material such as polyethylene or polypropylene dielectric. The arrester works by allowing a controlled current or arc to flow through the dielectric medium which absorbs the excess voltage and dissipates the current.The 2045-40-BLF provides an effective and reliable method of protection from lightning damage and electrostatic discharges. The current-limiting capacitance of the GDT is beneficial as it limits the surge current to a certain value thereby limiting the risk of overvoltage damage to other components. The GDT arrester also has a voltage-limiting mechanism that ensures the voltage is limited to a predetermined level. In addition, the 2045-40-BLF is designed to operate at temperatures as high as -40°C and can withstand high humidity levels up to 80%.The 2045-40-BLF is also designed with a triple protection feature, which includes an external resistor that will limit the surge current to the arrester, an internal resistor that will limit the surge current away from the system, and a surge voltage-limiting circuit which will limit the surge voltage to a maximum of 8 kV.The 2045-40-BLF is widely used in industrial environments, including electrical systems, telecommunications equipment, and computer networks. It is also used in residential homes and commercial enterprise buildings to protect against lightning strikes and other forms of voltage transients.Overall, the 2045-40-BLF is an effective and reliable form of protection from externally-induced transients. Its current-limiting capacitance and voltage-limiting features make it suitable for protecting against lightning damage and electrostatic discharges. The triple protection feature also provides a robust level of protection. The device is also designed to withstand large temperature fluctuations as well as high humidity levels, making it an ideal arrester for use in demanding environments.
