Iec 60815-2 Pdf May 2026

IEC 60815-2 provides a modern, scientifically refined methodology for dimensioning ceramic and glass insulators in polluted AC environments. Its introduction of SPS classes with ESDD ranges, shape factors, and voltage corrections makes it far more accurate than the 1986 version. For any utility or engineer designing outdoor HV AC lines or substations in polluted areas, compliance with this standard is essential to prevent flashovers and ensure long-term reliability.

The official document, available as a DRM-protected or watermarked PDF from the IEC Webstore or national standards bodies (like ANSI, BSI, DIN), contains approximately 50-60 pages of technical guidelines. Here is a section-by-section breakdown:

IEC provides ranges mapping ESDD/NSDD to pollution severity levels (light, medium, heavy). These categories inform design choices: higher pollution → larger creepage distance or hydrophobic/recoverable surfaces.

The iec 60815-2 pdf goes beyond simple tables. It instructs engineers to apply correction factors for:

IEC 60815-2:2008 is the second part of the IEC 60815 series. It provides specific guidelines for the selection and dimensioning of ceramic and glass cap-and-pin, long rod, and post insulators used in AC overhead lines and substations under polluted conditions. The official document

The standard replaces the older IEC 60815 (1986) and introduces more refined pollution classes and a systematic approach to determining the required Unified Specific Creepage Distance (USCD).
