As cnkuangya Senior Engineer Dr. Zhang Wei emphasizes: “The surge protection landscape has fundamentally changed. Traditional AC-only SPDs are inadequate for DC applications where fault currents don’t have natural zero-crossings, and energy dissipation requirements differ dramatically. Selecting the wrong SPD doesn’t just risk equipment damage\u2014it can create false security that leads to catastrophic failures.”<\/p>\n\n\n\n

Statistics reveal that electrical surges cause approximately 35% of all electronic equipment failures, resulting in annual global losses exceeding $26 billion. With the proliferation of DC systems in renewable energy and transportation, the demand for specialized DC surge protection has skyrocketed by 400% over the past five years. As cnkuangya Senior Engineer Dr. Zhang Wei emphasizes: “The surge protection landscape has fundamentally changed.
