33kV 10kN composite line post insulator

Usage of 33kV 10kN composite line post insulator
The usage of 33kV 10kN composite line post insulator is very similar to porcelain 33kv line post insulator. This type of composite insulator is used to support conductor and insulate the wire from ground. The end fitting was fixed on wooden cross arm or steel cross arm.
For wooden cross arm the spindle should be longer
For steel cross arm the spindle should be shorter
