In high-voltage electrical systems, insulation isn’t just about preventing short circuits—it’s about designing components that withstand environmental challenges like pollution, humidity, and contamination. One critical factor in this equation is insulator creepage distance, the path along an insulator’s surface that prevents leakage currents. In this article, we’ll explain why creepage distance is vital, how to optimize it, and why products like pin insulator creepage distance-optimized designs or disc insulator units are essential for reliable energy transmission.
