Construction for double circuits

[mainline]

My utility loves to have us build stuff without giving us standards, then the engineers bitch when we build it how we want. What I'm looking for is how lineman at other utilities build overbuilds when they have to stick the top circuit. We glove 12kv but stick 35kv. I'm just looking for what people have found to be easiest spacing between circuits for sticking. I'm hoping PA Ben reads this because I know he sticks all the time. If the engineers won't help us out we'll help ourselves. Thanks guys

Every double circuit that we have reconductored in Ohio has always been 6' spacing between the arms.. In some situations though we could go 8' Hope this helps.

For any new construction we go 6' between circuits & 5' between phases if we are using Xarms we go 6' between them & 10 ' down for the neutral.

That is what we have been doing so thanks for the feedback. Lewy forgive my ignorance but what is a cct. I don't recognize the term. Thanks again guys.

i'm guessing he meant it to stand for circuits as that is what were talking about here.

i'm a big fan of spun arial cable... its 3 4/o cables attached to a messanger. its good for 15kv. you install it one foot below the secondary.its great for express feeders when you don't have any taps to deal with. no need to install new poles either.its rather expensive but after you factor in the labor costs its a deal.

We saw a lot of that out a RGE during their ice storm a few years ago. They ran it 4 kv as an actual distribution circuit. They would tap off from it with bolted connections. Bizzare, it would work great how you described it. Our utility looked at it a few years ago, but they decided it was to expensive. Now the engineers want spacer as express circuits. Its bullet proof, but a pain in the a%^ to work especially at 35kv. Unfortunately, lineman don't get much say.

One company near me has 10' for hotsticking their 34kv distribution over top of their underbuild with a 6' minimum.

That's how we build it also 10' (7' minimum) between 34 and the local circuit

the more clearances you can get between phases & circuits the better, but it starts to get expensive when you start having 3 & sometimes 4 circuits on a pole you need a tall pole & therefore big trucks.
