Coaxial surge protector for video transmission networks

CXC surge protectors are designed to protect sensitive equipment, connected to coaxial lines as computer networks, video-transmission, against transient surge voltages and disturbances created by lightning. The scheme of CXC, gas tube/clamping diode hybrid association allowing heavy discharge current and low residual voltage.*

CXC06-B/MF is a version with BNC connector male/female.

The efficiency of coaxial protectors is highly dependent on proper installation, in particular their connection to the earthing network of the installation.
The following installations rules must be strictly observed to ensure the efficiency:

  • Equipotential bonding network: all the bonding conductors of the installation must be interconnected and connected to the installation earthing network.
  • Optimized connection of the protector to the bonding network: to reduce the residual voltages during lightning discharge currents, the connection of the protector to the bonding network must be as short as possible (less than 50 cm) and has a proper cross section (at least 4 mm²).

The «feedthrough mounting» versions perfectly meet all these requirements.
Warning: Carefully remove all paintings or insulating coatings to ensure good contact..

  • Location of the protectors: they should preferably be placed at the entrance of the installation (to limit the penetration of lightning currents) and also near sensitive equipment (to enhance protection).
