Iec 60815-2 Pdf Jun 2026

Before selecting an insulator, engineers must qualify the environment. The standard classifies pollution into five Site Pollution Severity classes:

: Identify the maximum continuous operating AC voltage. iec 60815-2 pdf

Once the SPS class is established, IEC 60815-2 helps determine the . The USCD is the total creepage distance of the insulator divided by the highest operating voltage of the system (expressed in mm/kV). Before selecting an insulator, engineers must qualify the

The PDF provides exact mathematical equations to correct creepage distances based on altitude, insulator diameter (larger diameters collect more pollution), and mounting angles (horizontal vs. vertical strings). The USCD is the total creepage distance of

To understand Part 2, it helps to see how the complete standard is organized:

Select glass and ceramic profiles that leverage natural washing from rainfall effectively. The 4-Step Selection Methodology
