Product Description

Coaxial Surge Protector Rf Antenna Arrestor , Surge Protective Device

 

 

Product Description

OBVW is the series of devices for discharging transient overvoltages induced in coaxial lines. In accordance with IEC 61643-21. Coaxial format.

 

Suitable for the protection of radiofrequency transmission and reception equipment. By their nature, they are highly exposed to induced transient overvoltages (surges) associated with meteorological activity.

For BNC, F, N, TNC connectors.

Ideal for the protection of transmission and reception systems such as TV and radio antennas, closed circuit TV (CCTV), alarms, etc.

Transient voltage surgesin lv power lines
Transient overvoltages are voltage surges that can reach tens ofkilovolts with a duration of the order of microseconds.Despite theirshort duration, the high energy content can cause serious problemsto equipment connected to the line, from premature aging to
destruction, causing disruptions to service and financial loss.Thistype of surge can have various different causes, including
atmospheric lightning directly striking the external protection(lightning rods) on a building or transmission line or the associatedinduction of electromagnetic fields on metallic conductors.
Outdoor and longer lines are the most exposed to these fields,which often receive high levels of induction.
It is also common for non-weather phenomena, such as
transformer centre switching or the disconnection of motors orother inductive loads to cause voltage spikes in adjacent lines.
 
Surges in telecom andsignalling networks
Surges tend to induce currents in allmetal conductors; not only are thepower lines affected, but so are allcables to a greater or lesser extent,depending on the distance to the focusof the surge.
Although a lower current is induced,the effect produced is equally or moredestructive, due to the greatersensitivity of electronic equipmentconnected to communications lines(telephone, Ethernet, R, etc.).
 
Importance of theground connections
Overvoltage protectors (SPD) divert excess energy toground, so limiting the peak voltage to an acceptablevalue for connected electrical equipment.
A ground connection in adequate condition is, therefore,a key aspect for effective protection against overvoltages.Monitoring ground connection condition guaranteesproper operation of surge protection devices.

Application SPD:

• SPDs for CCTV is mainly used for supervisory control system, preventing product from lightning
strike and surge.
• Protect the video equipment effectively and ensure the image can display normally5.Inhibit the
overvoltage pulse issue fromthe transmission line on the camera effectively, Avoiding the video
surveillance equipment damage due to overvoltage pulse.
• Offer surge protection for almost any products application in power, instrumentations and controls,
network and data lines, coax and etc.
• For Radio Antennas, GPS Antennas, CATV, CCTV and Satellite TV.
