Application Of Surge Arresters In Coaxial Cable Video Transmission For Analog Cameras

In coaxial cable video transmission systems, the 132kv surge arrester surge protector serves as a compatible connection with cameras, transmission lines, and display/recording equipment. Typical devices connect analog cameras to the monitoring center via BNC or F-type connectors.

The 15 kv surge arrester surge protector is connected in series in the video signal link. Its design considers matching the video signal bandwidth with the standard impedance of the coaxial cable (typically 75Ω) to avoid signal reflections or image distortion.

In the event of a lightning surge or other overvoltage transient, the 22 kv lightning arrester surge protector shuns the inrush current through its internal gas discharge tube and TVS (Transient Voltage Suppression) component, preventing high-voltage surges from propagating along the coaxial cable to the camera or recording system.

For typical analog CCTV monitoring systems, the 220 kv lightning arrester surge protector is directly compatible with common BNC connectors, offering easy installation with virtually no noticeable attenuation to video signal quality (very low insertion loss).
