Let’s dive into what this specific standard contains, why you need the PDF on your desktop, and how it saves your medium and high voltage lines from failing.
Longer strings add weight and wind load. If the existing tower cannot support 18 units, you either: iec 60815-2 pdf
| Term | Meaning | |------|---------| | | Unified Specific Creepage Distance – creepage distance (mm) divided by √3 × nominal line-to-line voltage (kV). Units: mm/kV. | | SPS | Site Pollution Severity – a classification of pollution levels at the installation site. | | DD | Deposit Density (mg/cm²) – Non-soluble deposit density. | | ESDD | Equivalent Salt Deposit Density (mg/cm²) – Soluble pollution converted to equivalent NaCl. | | Creepage distance | Shortest distance along the insulator surface between metal fittings. | Let’s dive into what this specific standard contains,
A: The old standard gave fixed creepage (20 mm/kV for light, 25 for medium, etc.). The new 60815-2 gives ranges and introduces correction factors, making it more accurate and flexible. Units: mm/kV
