Electrical Engineering MCQ on Power Transmission
Suspension type insulators are employed for voltages beyond:
- 230 V
- 11 kV
- 13 kV
- 33 kV
Correct answer: 4. 33 kV
Explanation: A suspension type insulator comprises of number of porcelain insulator units connected with each other by metal links to form a flexible string.
A suspension insulator separates the line conductors and supports them electrically.
One end of suspension insulator connects to the cross arms of transmission line while other end supports the conductor.
