Product Overview
The model of gas tube lightning arrestor is TD-FDN-KKF-4.Gas Discharge Tube Surge Protector utilized a gas-filled discharge tube(GDT). The GDT works as an insulator but can be automatically conductive in very short time when the lightening current flows into the protector, then the lightening current will be diverted to earth via outer contact and grounding means. Once the surge subsided, theGDT revert to its original condition, and be ready fornext spark-over.It can work repeatedly if on damage done to the GDT and the maintenance is easy since the GDT is replaceable. It has the characteristics of wide frequency range, low vswR, low insert loss and easy installation.(Some models were developed with CITEL).




Maximum Discharge Current (Imax)
The maximum discharge current represents the gas discharge tube's ability to withstand surges. When selecting a gas discharge tube, consider:
The lightning activity level of the system environment.
The test level requirements for surge protectors, such as Iimp and Imax as specified in the IEC 61643 standard. Generally, products with an Imax of 10kA or higher should be selected. For harsh environments, models with an Imax of 20kA or higher should be selected.
