The External Gap Lightning Arrester (EGLA) is an essential component in electrical power systems, designed to protect transmission and distribution lines from lightning-induced overvoltages. It utilizes an external air gap to control and safely discharge excessive voltage, preventing damage to electrical infrastructure. With high-voltage protection capabilities, EGLA ensures insulation coordination, preventing flashovers and limiting overvoltage stress on electrical equipment.

Built for outdoor applications, EGLA is resistant to harsh weather and UV exposure, making it a reliable solution for long-term use. Its self-healing mechanism minimizes maintenance needs, enhancing overall system efficiency. Commonly used in transmission and distribution lines, substations, and industrial power systems, EGLA helps improve system reliability, reduce outages, and ensure operational stability.
