based on the specific pollution levels of a site. This part of the standard specifically excludes polymer or composite insulators, which are covered in Part 3 of the 60815 series. Key Technical Concepts Site Pollution Severity (SPS):
Because water films form readily on glass and ceramic, the geometry governed by IEC 60815-2 is the primary defense mechanism against flashovers: iec 60815-2 pdf
A: Informatively, yes. Annex B provides guidance on "maintenance measures" including periodic washing, silicone grease application, and RTV coatings.

is a critical technical specification for power systems engineering. It provides a standardized framework for selecting and sizing porcelain and glass insulators to ensure reliability in environments where dust, salt, or industrial pollutants could otherwise cause catastrophic electrical flashovers. iTeh Standards Purpose and Scope
Benefit from easy visual inspection. If a flashover or mechanical stress damages a glass shell, it shatters completely, making the fault immediately visible to maintenance crews. The official PDF can be purchased from several
System voltage (Um) = 145 kV (max operating voltage for a 132 kV system). Required creepage = 38 mm/kV × 145 kV = 5,510 mm .
Before diving into the selection procedure, it is helpful to understand several key terms that appear throughout IEC 60815‑2.
