BNC, N, F CCTV Surge Protection Device ,20KA Lightning Arrestor
OBVT-BNC
Coaxial BNC Video Surge Protectors are designed to guard computer
network system that includes the monitoring system of security
system, coaxial signal transmission and close -circuit TV,
satellite communication system.
OBVT 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.

How to choose a suitable power arrester:
When choosing lightning arresters to protect different types of
equipment in an area, the following factors should be considered
comprehensively:
●The intensity of thunderstorms in the area, the number of days of
thunderstorms and the parameters of the maximum discharge current
and the probability of occurrence;
●The value of the protected equipment;
●The level of impact resistance of the protected equipment;
●The social importance of protected equipment;
●Determine the power surge arrester with different protection
voltage UP and discharge current;
The main parameters of the lightning arrester
(1) Nominal voltage Un: The additional voltage of the maintained
system is consistent with it. In the information technology system,
this parameter indicates the type of maintainer that should be
selected, and it indicates the effective value of the communication
or DC voltage.
(2 Maximum continuous voltage Uc: The maximum effective voltage
value that can be permanently applied to the designated end of the
lightning protector without causing changes in the characteristics
of the lightning protector.
(3) Nominal discharge current In: The lightning protection device
is not damaged by applying a standard lightning wave with a
waveform of 8/20μs to the lightning protection device for 10 times.
(4) Maximum discharge current Imax: The peak value of the maximum
impulse current that the lightning protector can withstand when a
standard lightning wave with a waveform of 8/20μs is applied to the
lightning protector for one impact.
(5) Voltage protection level Up: The voltage protection level of
the lightning arrester in the case of In.
When selecting the type, the Uc of the lightning arrester must meet
the system voltage, the flow rate must meet the use requirements,
and the protection level must be lower than the equipment withstand
voltage.
