Subject: Selection and dimensioning of high-voltage insulators intended for use in polluted conditions. Part 2: Ceramic and glass insulators for A.C. systems.

This is the core of the standard. The IEC 60815-2 PDF provides a systematic method to:

Based on the pollution class, the standard provides a table (Table 2 in the original document) that gives the minimum nominal specific creepage distance (in mm/kV line-to-line voltage).

| Pollution Class | Specific Creepage Distance (mm/kV) | | --- | --- | | a – Light | 16 – 20 | | b – Medium | 20 – 25 | | c – Heavy | 25 – 31 | | d – Very Heavy | 31 – 43 | | e – Extreme | > 43 | Classify the pollution level into one of five classes:

These values assume a standard insulation profile. If using anti-fog (deep-rib) profiles, lower values may be permissible.

Do not risk using a bootleg copy for a live transmission line design. Insurance and regulatory authorities will demand proof of use of the correct standard.
