حریم شبکه های برق

طبق استاندارد سیم های هوایی در شبکه فشار ضعیف بایستی دارای حداقل فاصله ای از زمین و ساختمان ها و سایر شبکه ها باشند.

این فاصله بسته به شرایط محیط ووضعیت آب و هوای هر منطقه خاص می باشد در ایران نیز این فاصله ها استاندارد شده که به شرح زیر می باشد:

الف ـ فاصله آزاد در ساختمان ها و اسکله ها و درختان

سیم های فشار ضعیف بایستی از ساختمان ها به اندازه ای فاصله داشته باشند که افراد بالغ نیز به آن ها دسترسی نداشته باشند برای این منظور بایستی فاصله افقی سیم ها ی فشار ضعیف تا400ولت ،از خارج ترین نقطه ساختمان حداقل یک ونیم (1/5)متر و فاصله عمودی آن ها از بلندترین نقطه بنا 3 متر باشد همچنین برای جلوگیری از خطر احتمالی نصب تیرها در مقابل پنجره ها و یا بالکن ساختمان ها مجاز نمی باشد.فاصله سیم برق 20 کیلو ولت تا تاسیسات ساختمان باید3 متر باشد.

Hi there! I know this is kinda off topic but I'd figured I'd ask.

Would you be interested in exchanging links or maybe
guest authoring a blog article or vice-versa? My blog discusses a lot
of the same topics as yours and I think we could greatly benefit from each other.
If you happen to be interested feel free to
send me an email. I look forward to hearing from you!

Great blog by the way!

Hello! I know this is kind of off topic but I was wondering
which blog platform are you using for this
website? I'm getting sick and tired of Wordpress because I've had issues with hackers
and I'm looking at alternatives for another platform.
I would be fantastic if you could point me in the direction of a good platform.

When some one searches for his required thing, thus he/she wants to be
available that in detail, therefore that thing is maintained over here.

Definitely believe that which you stated. Your favorite
justification seemed to be on the internet the simplest thing to be aware of.

I say to you, I definitely get irked while people consider worries that they just don't
know about. You managed to hit the nail upon the top as well as defined out the whole thing without having side-effects , people
can take a signal. Will probably be back to get more. Thanks

Hi! I just wanted to ask if you ever have any issues with hackers?
My last blog (wordpress) was hacked and I ended up losing a few months of hard work
due to no data backup. Do you have any solutions to stop hackers?

I read this paragraph fully regarding the difference of hottest and earlier technologies, it's
remarkable article.

I was wondering if you ever thought of changing the layout of your
site? Its very well written; I love what youve got to say.

But maybe you could a little more in the way of content so people could connect with it better.
Youve got an awful lot of text for only having one or two pictures.

Maybe you could space it out better?
