Earthing Accessories Multi Point Air Terminal
🛠️ What is a Multi Point Air Terminal?
A Earthing Accessories Multi Point Air Terminal (also known as a Multi Spike Lightning Arrestor or Multi-Tip Air Rod) is a specialized component of a lightning protection system. It consists of multiple pointed rods or spikes made of high-conductivity copper or aluminum, mounted on a base. The terminal is designed to intercept lightning strikes and safely transfer the high-voltage current to the ground via a down conductor and earthing system.

🌩️ Purpose & Function
- Acts as a strike-receiving point for lightning
- Reduces the risk of structural damage by offering preferential discharge points
- Multiple tips increase the ionization area and effectiveness
- Safely channels lightning energy into the earthing system
⚙️ Key Features
- Multiple sharp copper/aluminum spikes (typically 3, 5, or 7)
- Mounted on a central rod or base plate
- High conductivity and corrosion resistance
- Can be installed on buildings, masts, chimneys, solar panels, or towers
- Supports connection with flat strip or round conductor
