Axis Lightning Arrester’s objective is to become the point of discharge for the lightning bolt, instead of the bolt hitting a random object such as a solar panel or the side of the building. By becoming the point of discharge, the electricity can be safely conducted into the ground using the entire lightning protection system, protecting the structure or solar park.
As per NFC 17-102, the ΔT for an ESE Lightning rrester should be at least 10μs – this means that the emission time of the ASLA ESE is at least 10μs faster than those from a Franklin Rod. Our range of ASLA ESE products ranges from a ΔT of 10μs to 60μs, depending on the requirements of the project.
| Model | Radius of Protection (m) | Height (mm) | Body Diameter (mm) | Diameter of Rod Maximum (mm) |
|---|---|---|---|---|
| ASLA 15 | 58 | 321 | 105 | 20 |
| ASLA 30 | 71 | 341 | 132 | 20 |
| ASLA 60 | 107 | 400 | 205 | 25 |
The area protected by ASLA is determined using the early streamer emission test method as per NFC 17 102 Standard and it is preferred to have ASLA installed on the highest part of the structure.
The protected area is delineated by a surface of revolution defined by the protection radii corresponding to the different considered height h and which axis is the same as the one of the air terminal as per the below figure, (source: NFC standard).
The ASLA system is based on the time difference (ΔT) between the emission time of a conventional lightning arrester and an early streamer emission lightning arrester, as demonstrated in high voltage testing laboratories. This emission from the ESE is generated by storing energy from the ambient electromagnetic field or static charges at the time of the lightning events.
In normal conditions, the air terminal stays in standby mode. However, there is a spike in the ambient electrical field when a storm approaches the site. This spike causes the timely release of the stored energy, generating an upward leader from the tip of the ESE lightning arrester. This upward leader moves toward the downward leader from the storm clouds, creating a path for discharge. The bolt then passes safely through the conductive body of the ESE Lightning Arrester to the down conductors and finally safely into the ground, protecting the building or solar project. This working principle allows for an enhanced radius of production provided by Early Streamer Emission Lightning Arrester than by a conventional lightning rod.
Working with a reliable lightning arrester manufacturer is crucial to ensure the highest quality and performance of your lightning protection system. Whether it’s a conventional or ESE lightning arrester, a trusted supplier uses advanced materials and conducts rigorous testing to meet international safety standards. These devices are engineered to safely divert the damaging effects of lightning away from structures by channeling the surge through the high voltage terminal and into the ground terminal, effectively protecting both people and assets.
Choosing the right lightning arrester manufacturer not only guarantees durability and efficiency but also provides expert guidance on installation, grounding, and maintenance. This ensures your electrical installations, buildings, and sensitive equipment remain safeguarded against unpredictable lightning strikes—offering peace of mind and compliance with global standards.
As a leading lightning arrester manufacturer, Axis offers a complete range of tested and certified solutions with unmatched product quality, fast delivery, and expert technical support across India and international markets.
Axis Smart Lightning Arrester (ASLA) is composed of one main striking point, emission device, fixing element, and a connection to the down conductor.

How to Install an Early Streamer Emission (ESE) Lightning Arrester
Proper installation of an ESE Lightning Arrester ensures optimal protection and compliance with IEC standards. Follow these steps for safe and efficient installation:
1.Choose the Correct Location:
Mount the ESE Air Terminal at the highest point of the structure to ensure maximum coverage and an unobstructed path for upward streamers. The arrester should extend above all nearby structures or metallic components.
2.Install the Mounting Mast:
Securely fix the supporting mast using corrosion-resistant brackets or clamps. The mast must be mechanically strong and properly grounded. Ensure that the mast height and position meet the radius of protection defined in IEC 62305 and NFC 17-102 standards.
3.Mount the ESE Air Terminal:
Attach the ESE lightning arrester to the top of the mast. Tighten all fasteners securely to withstand high wind speeds and vibrations. The arrester should be vertically aligned for accurate streamer emission.
4.Connect the Down Conductor:
Use a certified copper or aluminum down conductor to create a direct, low-resistance path to the ground. Connect it firmly to the base of the arrester using appropriate clamps. Avoid sharp bends (minimum bending radius: 20 cm) to prevent impedance build-up.
5.Grounding System Connection:
Connect the down conductor to an effective earthing system, maintaining an earth resistance below 10 ohms. The grounding system may include chemical earthing electrodes or copper-bonded rods as per site conditions.
6.Install the Lightning Strike Counter (Optional):
To monitor lightning activity, install an analog or digital lightning strike counter along the down conductor at an accessible height. Ensure proper alignment and weatherproof sealing.
7. Inspection and Testing:
After installation, check all electrical and mechanical connections. Conduct an earth resistance test and verify the continuity of the down conductor. Annual inspection is recommended to maintain performance and compliance.
