State the four methods of laying of cable. State precautions while laying of underground cable in the situation : (i) Minimum clearance between cable and water pipe line when running in parallel. (ii) Minimum clearance between cable and water pipe line when running in parallel. (iii) If cable is laid through pipe what should be diameter of pipe. (iv) When more than one cable is to be laid in the same trench, what should be minimum spacing between two cables ?  

1 Answer

Answer :

(i) Minimum clearance between cable and water pipe line when running in parallel:-

 0.5 mtr.

(ii) Minimum clearance between cable and water pipe line when running in parallel:-

 0.5 mtr.

(iii) If cable is laid through pipe what should be diameter of pipe:-

 Diameter of pipe is 2 to 3 cm, greater than cable diameter

(iv) When more than one cable is to be laid in the same trench, what should be minimum

spacing between two cables :-

 Then minimum 30 cm spacing is provided between 2 cables
