Shree Copper And Electricals

9 kV Copper Lightning Arrester is a reliable high-voltage protection device used to shield electrical systems from lightning strikes and voltage surges. It offers excellent conductivity, corrosion resistance, and long-lasting performance.

• ESE Air Terminal: The topmost unit containing the ionization/triggering system.
• Mounting Mast: A mechanically strong rod (often GI or stainless steel) that supports the terminal at the highest point of the structure.
• Down Conductor: A low-impedance cable (typically copper or GI) that carries current from the terminal to the earthing system.
• Earthing System: Specialized electrodes (like chemical earthing) designed to dissipate electrical energy safely into the earth.
• Lightning Strike Counter (Optional): An analog or digital device to track the number of times the system has intercepted a strike.

• Central Spire: The main vertical rod that acts as the primary attractor.
• Lateral Spikes: Four spikes typically angled at 45 degrees. These create a larger "capture area" by ionizing the air around the rod, essentially widening the protective umbrella.
• Rod Body: Usually a solid core of steel or brass with a heavy copper coating (electrolytic copper bonding) to ensure high conductivity and durability against oxidation.
• Base Plate: A flat metal plate with pre-drilled holes for mounting the rod securely to the highest point of a roof, chimney, or tower.
• Connector Terminal: A threaded or clamped section at the base used to attach the down-conductor (copper strip or cable).

1. Interception: During a storm, the sharp spikes concentrate the electrical field, attracting lightning that would otherwise hit the structure.
2. Conductivity: Because copper is an excellent conductor, the arrester handles the massive surge of current (millions of volts) without melting or sustaining significant damage.
3. Protection Zone: The 5-spike configuration typically creates a "cone of protection." For a standard 1-metre rod, this usually protects everything within a 45-degree angle from the tip, covering a ground radius of about 2 to 3 metres.

• 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

• 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.
