To help me provide more specific information, are you looking for the used to calculate USCD, or do you need a comparison between Part 2 (ceramic/glass) and Part 3 (polymeric) insulators? Share public link

is the shortest distance along the insulator surface between the two metal fittings. Together with the system voltage it gives the specific creepage distance (usually expressed in mm/kV). iec 60815-2 pdf

If you are researching , consider these complementary standards: To help me provide more specific information, are

): Evaluates how deeply corrugated the under-ribs of the porcelain or glass are. Deep ribs trap air pockets but can accumulate highly localized salt crusts in desert environments. If you are researching , consider these complementary

This standard replaces the older IEC 60815 (1986) and moves away from simple look-up tables toward a more rigorous, site-specific design approach. It establishes how to determine the required to prevent insulator flashover based on environmental pollution levels. Key Content & Technical Focus

The standard moves away from simply calculating a minimum creepage distance based on pollution severity. Instead, it introduces a dimensioning process that considers:

: The standard analyzes how different shapes (e.g., standard, anti-fog, or open profiles) perform under various types of pollution like salt spray or industrial dust.
