Question

The voltage level used in the high-tension cables to transmit power is:

1. between 66 kV and 132 kV
2. up to 1000 V
3. up to 11,000 V
4. between 33 kV and 66 kV

Answer 1

Correct Answer - Option 3 : up to 11,000 V

Explanation:

Classification of underground cables on the basis of voltage level is given below

Type of Cable	Voltage level (kV)
Low tension (L.T.) Cable	0 – 1 kV
High tension (H.T.) Cable	1 – 11 kV
Super tension (S.T.) Cable	11 – 33 kV
Extra high-tension (E.H.T.) Cable	33 – 66 kV
Extra super-tension(E.S.T.) Cable	66 kV and above

 

From the given options, the voltage level used in the high-tension cables to transmit power is up to 11,000 V.
