An underwater electric power cable which has a minimum
radius of curvature to which it can be bent without damage
and which can be suspended between underwater suspension
points in no greater than a predetermined length for a
desired service life is layed by first laying a flexible
steel rope along the desired underwater course and
adjusting the rope position and length so that there are no
curvatures thereof less than the minimum radius and no
lengths thereof greater than the predetermined length, and
then, the cable is layed alongside the rope so as to follow
the configuration of the rope.

burial depth can be 5 metres for 132 kv .

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
