Surge arresters are designed to protect high-voltage equipment and power infrastructure from transient overvoltages caused by atmospheric discharges, switching operations, or emergency conditions in the power grid. They ensure the stable operation of power lines, transformers, substations, and other critical equipment, minimizing the risk of damage and downtime.

Surge arresters are installed in high-voltage networks of various voltage classes and perform a key function: rapidly diverting excess energy to ground, preventing it from entering the equipment. Thanks to modern materials and design solutions, they ensure a long service life, high mechanical strength, and resistance to harsh climatic conditions.
