Thunder Arrestors, also known as Lightning Arrestors, are protective devices designed to shield electrical systems from the damaging effects of lightning strikes and power surges. Installed in residential, commercial, and industrial settings, these devices divert high-voltage surges to the ground, preventing damage to electrical equipment and reducing the risk of fire and equipment failure. Thunder arrestors are essential for power lines, transformers, and communication systems.
