I am building a small resort and would like to know what type of wire I need for direct burial. I want to bury the wire from where the 3 phase comes in (around 40 meters to where I will put the circuit box) and then into my bungalows. So I will have some lengthy runs of maybe up to 150 meters. I am not sure how else to explain what I am doing. I would just hire an electrician but where I live in Lao they don't even know how to do standard wiring and I have never seen it buried in my area.

I looked at Homepro's site but none of it said wire for burial. Is there a number or name for what I am looking for?

You need steel wire armor (SWA) plus how many cores u need. The wire armor is normaly used as earth.plus size of each wire .ie how much load max are u going to use and while you are about it get the corect size terminals for each end of the wire u order . also u should put a yelow marker tape between cable and surface so if any one starts to dig in the future hope fully they will find buried cable tape warning befor the get down to your cable and damage it or kill themselves u should mark layout in your site drawings. call me if any thing not clear Dereky1 at skype(moderator is this is aloud)
