VALUE ENGINEERING ON CABLING SYSTEM FOR POWER PLANT
I am working in utility portion of Oil and Gas project. I should follow Canadian standards and codes or IEEE/ANSI in absence of that. A part of design work is cabling .Cables are 13.8 KV power, 480 V power and control and protection cables. I have following options, in the order of construction cost:
1- Direct burial
3- Cable Tray on the Pip Rack
4- Cable Tray on Cable Rack
I would like to have your expert opinion on advantage and disadvantages of each method.
Furthermore I would like to know how much is the safety clearances between electrical cables and gas pipes, water and steam pipes in each case, together with references to the relevant code or standard
