Pressure cables are generally not used beyond__________?
Correct answer: C. 66 kV
- A. 11 kV
- B. 33 kV
- C. 66 kV
- D. 132 kV
Explanation
Pressure cables use pressurised insulating material to suppress ionisation and void formation, but their construction becomes impractical at very high voltages. They are therefore generally limited to about 66 kV.
