10 Leading AC SPD Factory in China

Introduction to AC SPD

AC SPD (Alternating Current Surge Protective Device) is a crucial electrical device designed to protect electrical systems and equipment from the damaging effects of voltage surges. Voltage surges can occur due to various reasons such as lightning strikes, switching operations in the power grid, and electrostatic discharges. These surges can cause significant damage to sensitive electronic equipment, disrupt power supply, and even lead to safety hazards.

AC SPDs work by diverting the excess surge current to the ground, thereby limiting the voltage across the protected equipment to a safe level. They are widely used in various applications, including residential buildings, commercial complexes, industrial facilities, and power distribution systems.
