Is is possible to lay HT & LT (Power Cables) laying in one trench. you may arrange HT cable at bottom layer, and LT cable as a top layer.

Regards,

TD

Not knowing where your located at in this World, I would recommend checking with the local Code Enforcer as how they want the cables laid, if it's permissible, at what distance between them.
