Internal Type Bearing Insulators IEC
This type of support insulators are used as in-building busbar support and separator support insulators.
These insulators are divided into 2 main groups:
Internal Bearing Insulators in accordance with IEC 273 Norm
7.2-12-17.5-24-36-52-72.5 kV Operating voltage and
It is produced in 60-75-95-125-170-270-250-325 Impact Resistance stress levels.
Although these insulators are made for indoor use, the specific creepage distance is taken as 12 mm / kV in IEC Standard type insulators.
| Operating voltage (Max.) | 7.2 kV - 72.5 kV |
| Leakage Distance (Min) | 12 mm/kV - 16 mm/kV |
| Material | Porcelain |
| Glaze Color | Brown |
