Hello dear readers and the inhabitants of our site!
Everyone who has encountered construction or installation work knows well how long it takes to unwind and rewind the wires to connect the tool.
In this article, the creator of the YouTube channel "Creates DIY" will tell you how quickly and easily you can make a cable holder from PVC sewer pipes.

Materials
- Plug, socket
- 5 m cable 2X2.5 mm
- Sewer PVC pipes, plugs

- Self-tapping screws with a press washer
- handle
- Sandpaper.

Instruments, used by the author.
- Hacksaw, knife
-
-
-
- Ruler, square, marker.

Manufacturing process.
So, the wizard begins by preparing the plugs. Marks the center on them with the help of a square and a ruler. It is enough to draw a line along the ruler, turn the workpiece, and mark the second line. So quickly you can find the center of the circle. Drills an initial hole.


Then he flips the plug and drills the crown. The burrs are removed with a knife.


Trying on a segment of 2 inch pipe, it will be a sleeve. He puts on a cut piece of pipe, marks the cut line.


Slices the necessary workpiece, cleans its end face with sandpaper.



On the main body and the sleeve marks the holes for the cable, and cuts them out.

Marks the center on the plug for a 2-inch pipe, heats the pins on the handle, and fuses them into the end of the sleeve. Additionally fixes with a self-tapping screw.





Inserts the sleeve into the plug hole, closes the sleeve with a handle. On the inside of the sleeve, a couple of screws are screwed so that it is rigidly connected to the plug and does not slip.



All items are prepared, you can collect device.



Through the external hole, and the hole in the sleeve passes the cable, plugs in the socket, and inserts it into the sleeve.



Everything is ready, now the cable can be quickly unwound and unwound.


This is such a compact carry.



For convenience, you can fasten a clip to the wall, then the carrying can be easily fixed and removed if necessary. Of course, the size of the device can be increased, or reduced to suit your tasks. Now the cable will not get confused, and the cleaning time will be much less.



Thanks to the author for a simple but useful tool for the workshop and installation work!
All good mood, good luck, and interesting ideas!

I really heard about scrap from a real person ... Like, they wrapped an extension cord of a huge cross section and length on the scrap. There was nothing else suitable at the construction site ... (And the truth! Where did the piece of the board come from at the construction site? !!!)))). They brought it into the trailer, laid it ... And tomorrow, someone rewound a bit and turned it on. The crowbar is hot red.
That’s real man "saw it" ...

it is thought that he is still warming from the influence of the passing current

So what am I talking about !! In the bay, on a reel, or unwound - and the heat is generated the same ... Another thing is where it goes - to heat the air, or to melt the insulation!))))).
And nothing to do with any inductance ...

I recalled a joke about a jeweler
One day at a lecture Einstein was asked how great discoveries are made. He thought for a moment and answered:
- Let's say that everyone knows about something, that it is impossible to do. However, there is one ignoramus who does not know this. He makes a discovery.

I recalled a joke about a jeweler who was brought a thousand carat diamond for cutting, and no one undertook to process it. The jeweler gave the cut diamond to his apprentice. To the question of another jeweler- "What are you doing, Moishe, it is impossible to cut it," he answered- "You know that and I know, but my student Abrash does not know this, and he will do it."

irreversible changes begin (accelerated aging)
No, not my case. At work, I ordered the suppliers of 20m ball screw 2X1.5, brought the bay, packaged, brand new! It was a sin not to use it, all the more so as I knew it: they’ll carry it all the same! He made an extension cord, turned on the heater, without unwinding it all, in a couple of minutes - the end of the world! scratch

About scrap in the coil smiled! This is from the category of tales about "mercury antennas", devices that convert reactive electricity, which you have to pay for (although household meters do not consider it) to active, connect the generator to an electric motor to receive electricity, etc., and most importantly, you won’t convince them, if not themselves, then their friends saw everything with their own eyes, and it certainly works.

I didn’t specifically ask this question, but it was postponed in my memory that any insulation has its maximum permissible operating temperature, above which irreversible changes begin in it (accelerated aging), as a result of which the electric strength of the material decreases, the insulation resistance decreases (the minimum allowable is 0.5 Megohms). It seems that with heating, the insulation turns into a conductor, because coal is ultimately a conductor, and the smaller the insulation resistance, the greater the leakage current, and accordingly the heating according to the Joule-Lenz law. And yet, inside the bay (it doesn’t matter whether it is wound on a spool or assembled by a “snake”), the wire is heated not only from within by the conductors, but also by its neighbors, so it turns out that the released heat simply has nowhere to go but accumulate.

WHAT IT HEATS FOR !!!
I’m already afraid of my ignorance in this topic, but it seems that it is still warming up due to the influence of the passing current, and in my particular case, it can be assumed that the inner coils are also subject to the mechanical pressure of the subsequent layers, which, together with thermal softening of the insulation leads to its crushing and short circuit! However, we will wait for the results of the LeoBrun project - a! smile

. Now you can imagine what will happen with a compactly wound wire that heats up like a two hundred watt boiler.

But, again, let's focus on WHAT IT WAS HEATING !!!
Collect it in a dense shapeless pile - and the result will be the same !!! Winding "in the form of a transformer" does not give anything here !!!
Here, the spears are broken precisely because it "works like a coil", and "if you insert a crowbar inside, it will become hot" ...)))))

Maybe I'm drunk now and forgot everything
No, these are gaps in my education, the third part of the TOE was not read to us at the Institute, why is it for computer engineers? But we considered the reducers to be healthy, because although they are electronically computational, they are MACHINES !!! smile

I admit, with the absence of inductance, I got excited and replaced the concepts of “inductance” and “reactance” (anyway, in weightlessness the body has no mass) misled itself by a “non-induction resistor”. For the sake of curiosity, he calculated the inductances and magnetic field energy of his "cob" extension cord, which is wound on a coil from a welding wire of a semiautomatic device. PVA wire 2X1.5, 35 meters, on a coil of 55 turns. I won’t lay out all the calculations, I will only give the results: inductance 518 μH, magnetic field energy at 16 A - 0.06 J (suppose everything goes to wire heating) and finally the loss in the wire at 16 A (maximum allowable load) is 204 W (204 J, considering the time factor). If we compare the values ​​of 0.06 and 204, then the magnetic losses can be neglected. Now you can imagine what will happen with a compactly wound wire that heats up like a two hundred watt boiler.

Then how do the multilayer windings of transformers work, wound round to round, back and forth, and their efficiency is over 90%? scratch

That's honest ... Maybe I'm drunk now and I forgot everything)))
But before this case, I did not know that there are transformers in which half of the winding is wound in the opposite direction! ...
Are you serious ??? ... How can it work then, if the magnetic fields of the first half are quenched by the second half of the winding ...
Actually, I believe that this simply cannot be ...
Explain which transformer is made this way, and for what purpose? ....
And how does it work?
And the secondary winding, too, half "turns back"?
Well, at least kill me, I still, with foam at the mouth would prove that such a transformer simply can’t work !!! ... Yes, and now I want to ...)))))

Something new to make inductance dependent on current
And the old woman is a slammer! I laughed not weakly, of course I meant the magnetic flux ... sorry
The magnetic flux Ф penetrating each of the turns of the coil, in the general case, can contain two components: the magnetic flux of self-induction Фси and the magnetic flux of external fields Фвп: Ф = Фси + Фвп. The first component is magnetic flux caused by current flowing through the coilthe second is determined by magnetic fields, the existence of which is not related to the coil current - the magnetic field of the Earth, magnetic fields of other coils and permanent magnets. If the second component of the magnetic flux is caused by the magnetic field of another coil, then it is called the magnetic flux of mutual induction
there is no inductance there
And what is, in fact, inductance?
Inductance is a measure of the relationship between the current in a conductor and the magnetic field generated by it.
Inductance (or coefficient of self-induction) is the coefficient of proportionality between the electric current flowing in any closed circuit and the magnetic flux generated by this current
fields have a counter direction and are mutually destroyed
Given the reactive nature of the load, will the mutual destruction of the arising fields occur with the release of energy, or am I misunderstanding something? scratch

which will only increase the power factor (cosine phi).
incorrectly expressed, the reactive component will increase, the coefficient of course will decrease.

Something new so that the inductance depends on the current is usually the opposite. It's the same as saying "resistance depends on the current." And then there is no inductance there, Valery correctly said that the direction of the current in the “windings” is the opposite (if you imagine two wires in the form of windings laid side by side, or in another way, “winding into two wires”). Imagine that the “windings” are connected to a constant current source and determine the direction of the magnetic field in each “winding” according to the drill rule, and make sure that the fields are in the opposite direction and are mutually destroyed (by the way, induction-free wire resistors for high-frequency equipment are wound). But suppose that the inductance is still present, then we get reactance, which will only increase the power factor (cosine phi). And yet, the inductance of a multilayer coil is calculated as follows: L = (0.008 * Dk² * N²) / (3Dk + 9l + 10t)
Where
Dk - average diameter of the coil = diameter of the frame + thickness of the winding,
t is the thickness of the winding,
l is the length of the winding
N is the number of turns.

It depends on how many turns and what diameter (turns). Well, what a current.

Yes, do not care what current and how many turns ... Provided that exactly the same number of turns are wound in the opposite direction ...
Is not??? I remember that 35 years ago a resistor with a low resistance was needed. I decided to wind it with copper. (But it was sho - it was winding up))) .. I thought, I thought - but in reality it turned out wrong ... The ohmmeter showed something else (remember that such a separate device was in a black ebonite case?))) ... I found it by experience I needed three ohms ... I reeled ... And there - op-pa ... an inductance appeared, which I do not need ... (Painfully many turns of copper turned out))). A more advanced comrade advised to unwind, and then rewind to half, and the rest - in the opposite direction ... It helped!
So why doesn’t it help if the second wire is exactly the same length and as many turns, only "wound in the opposite direction"?

For 50 Hz, the inductance of a piano wire twisted into a coil does not play
It depends on how many turns and what diameter (turns). Well, what a current.
L = U / (I * w) = U / (2 * I * nf)

vice versa, it simply cannot get any currents !!!
Somehow I made an extension cord out of a small coil from a winding copper wire, the wire (freestanding) wound tightly, coil to coil. Without unwinding it all, I connected an oil household heater. Vo-o-from, in a couple of minutes the introductory machine knocked out! Short circuit in the innermost layer, I think because of the small diameter of the turns - the maximum inductance, something like that! scratch

One of the tightly rooted "error stamps" ... No "coil effect" occurs in single-phase extension cords and cannot occur !!! In order for this effect to be, you need to take the coiled extension cord and using one of its wires (or connecting both together), connect it to the circuit sequentially with the load!)))) And until the current flows along one conductor in one direction and, on the other hand, back, it simply cannot excite any currents !!!
Another thing is that, as correctly written above, all the wires are heated ...And if in the unwound state it "cools faster than it heats up" (you don’t even feel the heat by hand), then in the bay it cannot cool down ...
As an example - a Christmas garland. On the tree burns for days and nothing. And turn on the coiled one, right from the store - in a minute it will be noticeably hot ... But there is no coil there! Collected not in rings, but in a zigzag.)))))
Specifically, here - the length is small, the cross section (2.5) is huge ... I don’t want to count, but I would not be afraid to cut 2 kilowatts through it for 10 minutes, even when wound ...
And the second question ... And what, a five-meter can still not be completely unwound ???

For 50 Hz, the inductance of a piano wire twisted into a coil does not play. Another thing is that in a twisted form it is impossible to turn on a large load, from which the wire will start to heat up; cooling in the bay is much worse than in a single wire. In the old days, a five-meter extension cord-tee was sold on a reel, there it was stamped directly on the case - "16 A, at maximum load, remove the wire all the way" (I do not remember literally).

The biggest minus is that you can not use it in a twisted state, it will work like a coil

5 meters of wire and in your pocket is not a hindrance. How about 60 meters, or at least 20 meters? And also compact and efficient?
