Correct Answer - Option 4 : 1 kV
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
|
Therefore, from the above table low tension cables are generally used up to 1 kV.
