How does FPB distance relate to voltage ranges according to the material?

Explanation:
FPB distance is a clearance that scales with voltage to keep dielectric strength safe. When voltage rises, the electric field across gaps becomes stronger, increasing the chance of arcing or insulation failure. To maintain a safe margin, the distance must grow for higher voltage ranges. That’s why FPB distance increases as voltage ranges get higher — it ensures the same level of insulation reliability across the voltage spectrum.
