Bury 15kV cables under Lake
Bury 15kV cables under Lake
(OP)
Have you guys have any experience in burying the 15kV cables under the long lake. Since the lake is too wide, the client decides to cross the lake via underground. I think I can lay the cables on the bottom of the lake or do I need to bury the cables 3-4' deep below. What are the restriction, requirement etc. Should I rely on the DNR for requireements etc...
Any help would be appreciated...
Thanks

Several factors determine the depth of burial, which can be determined from a Hydrographic Survey.
Are there large boats on this lake that may use large anchors?

In case of failure of one or multiple cable consider in advance the consequences and the impact on the system. The use of additional feeder, cable in warehouse and qualify crew to do underwater repair should be consider before final decision.

Metal-armored submarine cables are typical for the application. Kerite, Okonite and Pirelli are a few providers. I believe the three also offer turnkey installation.

How wide is the lake? Would directional drilling be feasable?
