Cables, generally used beyond 66 kV are___________?
Correct answer: A. oil filled
- A. oil filled
- B. S.L. type
- C. belted
- D. armoured
Explanation
For voltages above about 66 kV, oil-filled cables are commonly used because the oil improves insulation and helps remove heat. Belted and S.L. cables are mainly associated with lower voltage ranges.
