Product Overview
The model of gas tube surge arrester is TD-FDN-JK 3G.Gas discharge tube (GDT) arresters are one of the most common types of arresters due to their reliability. Gas-tube coaxial RF surge protectors can divert large amounts of electrical energy and have relatively high operating power. Furthermore, these devices can be adapted to operate in the multi-gigahertz frequency range while also providing DC flow. A drawback of this type of arrester is that they typically require exposure to hundreds of volts for several microseconds before the gas inside the tube ionizes and becomes conductive. This can leave more sensitive RF electronics unprotected for extended periods, so GDTs are often paired with other forms of surge protectors.(Some models were developed with CITEL).
