The model of RF coaxial surge protector is TD-BLN-KK 900.Quarter Wave Coaxial Surge Protectorutilized 1/4 wavelength shorting stub working as the band pass filter. The frequency range can bechanged by modifying mechanical dimensions.As we learntfrom frequency spectrum, lightening wave is in low frequency (from hundreds KHz to Megahertz).When low frequency signals input, the centercontact and theouter contact will be short-circuitedby the shortingstub then the lightening current can be diverted tothe ground, therefore the high
frequency signals transmission will not be interfered and equipmentand instruments can work normally.The frequency range can be very wide and also in certain band. Featuring high power, it has a long service life.(Some models were developed with CITEL)
The principle of a quarter-wave arrester is based on the law of electromagnetic induction. When an electric field exists between a lightning cloud and the ground, an induction coil forms between the ground and the cloud. These coils receive charge from the cloud, generating a current that draws the charge to the ground.
The RF coaxial surge protector plays a crucial role in this process. Its lightning rod generates an electric field whose direction and magnitude are opposite to the electric field received by the induction coil. Consequently, the electric fields of the lightning rod and the induction coil cancel each other out, reducing the current in the induction coil and drawing the charge to the ground.
