Copper Lightning Arrester, 1 m, 12 mm

A Copper Lightning Arrester is a high-conductivity safety device installed at the highest point of a structure to intercept lightning strikes. It provides a low-resistance, controlled path to safely channel massive electrical discharges into the ground, protecting the building's structure, electrical systems, and occupants from fire or electrocution.Core Components Air Terminal (Rod): A pointed copper rod, often with multiple spikes (commonly 5), that serves as the first point of contact for a lightning strike. Down Conductor: Heavy copper cables or strips that carry the surge from the rod down the building's exterior. Grounding System: Copper earth rods or plates buried deep in the soil to safely dissipate the energy Technical Specifications Protection Radius: Typically offers a 45-degree coverage zone from the top point. Advanced ESE (Early Streamer Emission) models can protect a radius of over 100 metres. Standard Sizes: Commonly available in lengths of 1 metre (1000mm) or 2 metres, with rod diameters ranging from 14mm to 25mm. Efficiency: High-grade copper arresters are designed to withstand impulse currents up to 200 kA. Compliance: Most industrial-grade arresters adhere to international safety standards such as IEC 62305 or IS 2309. Why Copper is PreferredCopper is the industry standard for lightning protection due to its unmatched conductivity, which ensures the fastest possible discharge of current. Its natural resistance to corrosion makes it ideal for harsh outdoor environments, including coastal areas with high salt and moisture.
