Telephone Poles & Communication Wires

[Music] so before we get to the live telephone wires how those are used for the error of the shotgun has a model lesson he's going to show us on this telephone pole and this what do we call the server shotgun there's a resistor okay take it away so at the top of the telephone poles there'll often be a resistor holding one of the power lines and it will go like this if we're lucky if we're lucky then this wire runs over the telephone pole the telephone pole can be considered to be the lahi and the wire will be the conushalgarh bayhem and we have a good source of passage no lefties will need to be installed and this is the easiest way to make an a-roof there's another configuration that we'll often have is that the telephone the the power line is running on the side of the telephone pole like this so it doesn't run over the top of the telephone pole itself but it does run over the top of this fiberglass pole which is an extension or could be considered an extension of this and then if it's running over the top that would be considered to be algab of this i like using this as a demo because when we get out to the polls it's sometimes difficult to see when it's very high up but this is one of the things that we'll be looking for depending on what the the halacha criterion for that particular area which posik you're using some will only allow it when it runs like this and it goes over the top of the pole some will even allow it when it runs like this so which one would they allow ah so what they won't allow is as follows even those who are lenient sometimes the wire will be put over here generally when the road is turning so if the road turns the wire has to turn and they'll put it on the side when this wire is on the side it no longer is going over this extension and therefore you don't have to be very careful when using these types of surpasses to make sure that the wire that's on the top doesn't run like this or like this so the concept called tacho usually in an arrow the wire goes to the pole the rashad is going to show us what happens when the wire goes through the pole rabbi shotgun take it away so the sweet face of frank brings in one of his chuvas and perhaps the khaznish as well that when a wire not goes over the pole but goes through the pole that that's also considered to be al-gabov and that would be a valid form of its ursa passage some will use this and some will not how it applies to utility poles is a little bit more challenging so i'm going to go up in the bucket and give you a close-up view of how we do taco when it comes to a citywide area [Music] in this particular setup we have our lucky here that comes up to this wire and this wire is crossing the street to make it serious to the other side of the street this lechi in some aravind wouldn't be here because if you follow this wire and it continues it attaches to this bolt this bolt doesn't just screw into the pole it actually goes through the pole and comes out on the other side as you can see the nut on the other side over here that would be tahoe that this wire goes on top of the telephone pole in and that it goes through the telephone pole and it is above the section of the pole that is below it in this particular a-roof they want it to be mount smear so we put a lefty going up to the bolt and the bolt being an extension of the wire is considered to be underneath the wire in this particular scenario one of the interesting concerns that i had as a builder was do i bring the lucky up to the side and curve it to get underneath the wire or do i bring it in front of this wire and come out i chose to do it this way because this way the lucky remains straighter and it didn't run into an issue of piste chamois which we will discuss perhaps in another video and as well this is more like a keeper which you'll also learn about on daphiur alef that when your lefki bends in towards the direction that the source is going it is like a keeper another couple of things features that we have here are instead of using zip ties we always use aluminum ties because zip ties have a tendency with time to disintegrate and the uv rays destroy them and eventually what happens is your lefty moves and it's not underneath the wire anymore and the checkers don't always notice and the other thing is having standoff pieces that can hold your lefty in place is the most critical part of the left here is going to be under the wire at the top and that would be very secure at the top is really very essential to maintaining the cautious of your arrow another interesting debate regarding the installation of this particular material and this particular lockheed if you look here you'll notice that at the union of these two pieces of u-guard there's two pieces in the back and a piece in the front this was done because according to some opinions if we overlap them like this one piece is overlapping the other that may be considered mean hot hatsaad they wanted one to be on top of the other like this in order to satisfy those postkin when we installed this we have one piece on top of the other and we put a union piece over it and glued it together and then placed our brackets [Applause] other post can allow this configuration and depending on which post you're building for that's how you would determine how you want to do your unions when you're using u-guard
