Detailed Solution
Download Solution PDFThe desired minimum depth of laying from the ground surface to the top of the cable is as follows:
High voltage cables (3.3 kV to 11 kV rating) = 0.9 m
High voltage cables (22 kV, 33 kV rating) = 1.05 m
Low voltage and control cables = 0.75 m
Cables at road crossings = 1.00 mLast updated on May 29, 2025
