This document provides a systematic framework for engineers to select and size insulators—such as porcelain or glass—based on the specific environmental pollution levels they will face in service. Core Purpose and Scope
The standard is a critical technical guide for electrical engineers, focusing on the selection and dimensioning of high-voltage insulators for use in polluted conditions. Specifically, Part 2 provides detailed guidelines for glass and porcelain insulators used in AC systems. Overview of IEC 60815-2
The practical impact of this standard is most visible in the relationship between creepage distance and system voltage. To determine the required creepage distance for a specific insulator, engineers will apply the principles of the standard:
: Ensures the underside of the sheds stays protected from direct pollution accumulation. iec 60815-2 pdf
: The direct source for the latest version, amendments, and redline versions showing historical changes.
is an indispensable technical specification for the modern electrical grid. As the world's power systems face increasingly diverse environmental challenges—from coastal pollution to industrial contamination—engineers rely on this standard to prevent costly and dangerous insulation failures.
The specification uses classes to determine the required creepage distance: Pollution Level Basic RUSCD (mm/kV) Very Light Light Medium Heavy Very Heavy This document provides a systematic framework for engineers
Extreme environments, such as desert regions with salt-laden sandstorms or heavy industrial chemical clusters.
: Specific rules for DC systems (under development/upgrades). Core Methodology of IEC 60815-2

If you are working on a specific design project, please let me know:
To mitigate flashover risk without excessively over-designing substation towers and overhead lines, power systems follow the comprehensive guidelines of the IEC TS 60815 series . Specifically, governs the selection and dimensioning of ceramic and glass insulators for alternating current (AC) systems . 1. What is IEC 60815-2?
The official (Selection and dimensioning of high-voltage insulators intended for use in polluted conditions - Part 2: Glass and porcelain insulators for AC systems) is a copyrighted document. You can officially preview or purchase it through the following sources: IEC Webstore ANSI Webstore National standards bodies (like BSI, DIN, or AFNOR).
is a technical specification for the selection and dimensioning of high-voltage ceramic and glass insulators used in a.c. systems exposed to polluted environments . It complements the general principles in Part 1 to help designers calculate exact creepage distances and evaluate insulator profiles. Core Objectives The standard provides a structured method for engineers to:
For a practical application, engineers and utility planners can follow this structured approach, which the standard enables:
