Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube Arresters (GDT) are critical components of any electrical system, designed to provide protection against electrical surges. They are used to protect electrical circuits, such as those in overhead transmission lines, communication systems and telecommunication systems. GDTs are used to protect sensitive electrical or electronic equipment and installations from damage caused by high voltage surges or transients.

B88069X2840S102 application field and working principle

The B88069X2840S102 arrester is a single-stage gas discharge tube (GDT) and is specified for voltages up to 140VAC/250VDC for the protection of electronic circuits or equipment against transient overvoltage. It provides a reliable level of surge protection for sensitive electronic circuits or systems.The working principle of this arrester is straightforward, yet effective. The gas discharge tube consists of a cylindrical metal tube insulated from the circuit it is protecting by an electrically conductive insulator. The metal tube contains a high-pressure noble gas, usually Nitrogen, which is activated by an incoming overvoltage surge or transient. When this happens, the gas in the tube is ionized, disrupting the flow of the electrical current. This effectively redirects the surge or transient current away from the protected equipment or system, ensuring a safe level of protection.The B88069X2840S102 gas discharge tube arrester is uniquely designed to accommodate a wide variety of applications. This GDT is suitable for a range of applications, from industrial electronic equipment to DSL/PSTN interfaces. It is also highly reliable, with a good capability for withstanding repeated surge events, as well as a high level of temperature stability. The GDT also features a ratio of lower leakage current to higher discharge current, as well as a good energy absorption capability, making it ideal for applications that require fast response to surge events.To ensure the optimum performance of the B88069X2840S102 gas discharge tube arrester, several safety measures must be taken. These measures include proper installation and maintenance, as well as adequate size and placement of the GDT. Proper installation and maintenance includes making sure that the GDT is correctly and securely mounted in place, and that all connections are appropriately insulated and tight. Placement of the GDT must also be considered, making sure that it is in a suitable environment, away from any sources of heat, moisture or dust, which could cause it to become damaged.Ultimately, the B88069X2840S102 gas discharge tube arrester is a reliable and effective solution for protecting electrical circuits or equipment from transient overvoltages or surges. It is designed to provide a high-level of protection and be easy to install and maintain. With its wide variety of applications and reliable performance, it is an ideal choice for any electrical or electronic system.
