3.3 kV
6.6 kV
11 kV
33 kV
Answer is Right!
Answer is Wrong!
The correct answer is D. 33 kV.
Super-tension cables are a type of high-voltage cable that is used to transmit electricity over long distances. They are typically made of aluminum or copper and have a stranded conductor. Super-tension cables can operate at voltages up to 33 kV, which makes them ideal for long-distance transmission.
Option A is incorrect because 3.3 kV is the operating voltage of extra-high-voltage cables. Option B is incorrect because 6.6 kV is the operating voltage of high-voltage cables. Option C is incorrect because 11 kV is the operating voltage of medium-voltage cables.
