Outdoor solid core post insulators

Outdoor solid core post insulators are designed to comply with the demands of the level of electrical insulation and mechanical strength.

Outdoor solid core post insulators


The main feature of outdoor solid core post insulators:
Lightning impulse withstand voltage, dry
Switching impulse withstand voltage, wet
Power frequency withstand voltage, wet
Mechanical failing load
Minimum nominal creepage distance
Fixing arrangement of top and bottom metal fitting
Color of glaze

The insulation performance of a post insulator column is a function of the height, creepage distance, arcing distance of the insulating part as well as the number of insulator units for a defined height.

Outdoor solid core post insulators,lightning impulse withstand voltage, dry of 1050 kV and minimum failing load torsion 3KNm.
