8mm Aluminium Conductor for Lightning Protection Systems
The 8mm Aluminium Conductor is a critical down-conductor and bonding component used in Lightning Protection Systems (LPS) across buildings, solar plants, substations, and industrial infrastructure in India. Supplied by Earthing Mart, this conductor is engineered specifically for Indian soil resistivity conditions (10–200 Ω-m), aggressive monsoon cycles, and long-term outdoor exposure.
Designed to meet IS 3043, IEC 62305, and IEC 62561 requirements, the 8mm aluminium conductor provides a low-impedance, corrosion-resistant current path to safely dissipate lightning impulse currents into the earthing system—protecting life, equipment, and structural assets.

Product Overview & Working Principle of 8mm Aluminum Conductor
An 8mm aluminium conductor functions as a down conductor and equipotential bonding conductor within a lightning protection system. During a lightning strike, the air terminal captures the strike, and the aluminium conductor safely transfers the impulse current to the earth termination system.
How It Works (Step-by-Step)
-
Strike Interception – Lightning is intercepted by air terminals or mesh conductors.
-
Current Conduction – The 8mm aluminium conductor provides a continuous, low-resistance metallic path.
-
Impulse Handling – Aluminium’s conductivity and cross-section allow safe dissipation of high peak currents.
-
Earthing Dissipation – Current is discharged into soil via electrodes, considering Indian resistivity profiles.
This conductor is preferred where lightweight installation, corrosion resistance, and cost efficiency are required without compromising compliance.
