Why Dimensional Accuracy Matters
Post insulator dimensions — particularly shed spacing, total height, and mounting hole positions — are critical for interchangeability and proper assembly in substations. A post insulator that is 5mm too tall creates alignment problems for busbar connections. IEC 60383 specifies dimensional tolerances that must be verified on every production batch.
