 The proposition core of lighting arrester wiring is to consider the safe electricity basis to ensure the service life of LED street lamps, and it is necessary to consider comprehensively.
 
The outdoor application of led street lamp lightning arrester considers the following three factors : 

1. The lightning arresters with corresponding parameters are selected according to different use scenarios of street lamps, and the power standards of each country and region are different, so the wiring modes of various lightning arresters are not completely unified. 
2. Select the appropriate lightning arrester, you should be clear about which kinds of lightning arresters are included in the LED lightning arrester, lightning arrester external conditions to have the elements. We choose different situations. 
Third. Lightning arrester wiring considers the protection of cable and lamp safety connection. 
   Which kinds of lightning arresters are included in LED lightning arresters 

LED lamps and lanterns, like other street lamps and lanterns, its own design has been equipped with lightning arrester components, its parameters are usually 5kA, the maximum 10kA, such protection ability in the general urban environment can be so, but the road, mountain, riverside water, lightning multiple hit environment is not optimistic. 

1.The power lightning arrester we designed must be one to two orders of magnitude, such as 10kA ( 20Amax ). 
2.The protection end is divided into two, if the municipal power supply end is PVC pipe, it is necessary to configure the protection rectifier power supply constant current voltage source at the bottom of the metal rod. The protection grade is 3-4. 
3.The fifth stage of LED is the lightning protection components of lamps, low voltage potential precise clamping protection. Ensure 24v or 36v DC voltage safety. Here ‘ s a tip for precise clamping.
4. External environment ensures grounding resistance below 10 ohms. 
5.The service life and waterproof grade of lightning arrester. 
   Back to the proposition. How to ground 

1. The lamp metal tube is properly connected with the grounding terminal located at the bottom of the rod. Note that the grounding terminal cannot be omitted to ensure the proper connection of the terminal ; 
2. The movable tube, sleeve and other loose places of lamp post must be more than 16mm woven belt two connections ; 
3. The connection between lamp head and lamp pole must be the same as above ; 
4. The lamp head must have a grounding terminal, and the connection of the grounding terminal must be properly connected with the weaving belt of the lamp head and the pole. 
 
What kind of protective accessories are selected when LED street lamp lightning arrester wiring 
When the cable is connected to the lightning arrester, the waterproof connector and the waterproof junction box are indispensable. The waterproof connector connects LED street lamps and lightning arresters, and the cable branch of the waterproof junction box can play a good protective effect.
