Note: The system lightning protection does not guarantee that the equipment will not be 100% damaged by lightning; the power system must be multi-level lightning protection;
The complete lightning protection system includes external lightning protection and internal lightning protection. External lightning protection refers to: lightning receptors, down conductors, and grounding bodies, which are mainly used to defend against direct lightning strikes. Internal lightning protection includes: shielding, reasonable wiring, safe distance, equipotential connection, overvoltage protection, etc., mainly used to prevent lightning induction, ground potential counterattack, lightning wave intrusion, etc.


Tip: Lightning protection is probabilistic protection, and we cannot provide 100% protection.

First, lightning discharge itself has a certain degree of randomness, and lightning parameters have certain statistical properties, which determines that all protective measures based on these statistical characteristics of lightning parameters cannot provide 100% protection. Such as: direct lightning protection-shielding characteristics; lightning current amplitude, waveform, etc. have statistical properties;
Second, the lightning protection equipment cannot prevent the formation of lightning flashes;
Third, lightning protection devices cannot ideally eliminate all interference voltages/currents. The fundamental purpose of taking protective measures is to ensure that most of the energy caused by interference does not spread to the vulnerable parts of the device and the staff.
Finally, the cost of protection against high-level surges with a small probability of occurrence has risen sharply.

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.

What skills should lightning protectors have in the selection?
1.Confirm power supply system
First of all, you must determine what your power distribution system is like, whether it is TT, TN or IT system. After determining the power distribution system, you can choose the protection mode and wiring method of the lightning arrester to select the appropriate lightning arrester.
For example, TN-C uses 3P lightning protection device, TN-S uses 4P, TT uses 3P+N, etc.
2.Know the main parameters of the lightning arrester.

Q: Can I get some samples?
A: Yes, Sample orders welcomed.
Q: Can I use my own Logo or design on goods?
A: Yes, Customized logo and design on mass production are available.
Q:What is the delivery time?
A: 3 days for samples, 7-15 days for mass production.
Q: What is the payment term?
A: T/T, L/C at sight, West union , Paypal, etc.
