From Table 2 (Level d → 31–43 mm/kV). Choose 38 mm/kV as a conservative interim value.

: It provides guidance on insulator shapes, such as shed spacing, shed overhang, and "creepage factor," which are critical for performance in rain or coastal salt spray.

The most critical output of the IEC 60815-2 standard is calculating the required . The USCD is the total creepage distance of an insulator divided by the highest rms phase-to-phase voltage of the system.

Before selecting an insulator, engineers must quantify the environmental harshness of the installation site. Following the metrics defined in Part 1, pollution is classified into five classes: From Table 2 (Level d → 31–43 mm/kV)

When utilizing the IEC 60815-2 document for a project, the design workflow generally follows these steps:

, and select appropriate profiles (e.g., standard vs. "fog type") based on the site's pollution severity. Key Sections It is critical to know which part you need
