How to extend an electric wire in an apartment. How to extend a wire at home. Most common situations

Hello dear readers of the blog site. Recently I have written several articles regarding installation digital television in the country. Today I want to talk about how to lengthen antenna cable, if you need to transfer for best reception, or the location where the TV is installed is not suitable for comfortable viewing of TV shows.

In the article about I have already touched upon the topic of the need to purchase a high-quality coaxial cable in order to avoid the occurrence possible problems with signal reception. But I will tell you below what to do and what tools you need to purchase and really hope that everything will be as accessible and clear as possible.

Proper work done will not affect the quality of the received signal. If malfunctions occur or the quality has deteriorated after work, then it is worth checking all connections and assessing how quality materials were purchased.

Necessary tools and materials for antenna cable extension

If you need to move the TV to another room, or to a corner of the room, there is a shortage of wire length and the question arises of purchasing an additional piece. Before going to the store, be sure to inspect the existing one, evaluate the thickness of the central core, rewrite the markings, and it is best to cut off a small piece for clear example, at the time of buying.

In my opinion there are only two optimal ways lengthen tv cable. The first using “F” connectors, and the second using a “splitter” for possible further wiring to several devices.

I won’t talk about soldering, since this matter is quite complicated. When extending a television cable by soldering, it is difficult to achieve the desired wave resistance. And the junction itself will be very fragile.

So, let's look at both options in order.

How to extend a TV cable using “F” connectors

For this method we will need two f connectors and one f connection. Before proceeding with the extension, the wire must be properly “cut”. To do this, carefully remove the top shell without damaging the screen. We twist the shielded braid and bend it in the direction of the cable. We remove the foam insulation, thereby exposing the central core. The approximate length of the freed core should be about one and a half centimeters.

This operation must be performed on both ends that you want to fuse. After the completed operations, take the f connectors and carefully screw them onto the wire. Keep track of so that the central wire does not contact the outer shield.

For better fixation, the junction can be wrapped with electrical tape. This fixation will prevent your product from falling apart when bent or deformed.

This was the first way to extend a coaxial cable. Now I propose to consider the second option and, in my opinion, more practical.

How to extend a coaxial cable using a splitter

Let's first understand what a splitter is and what it is needed for.

A splitter is a small box with one input and several outputs. A splitter is designed to split a connected antenna into several TVs, or to one cable. When choosing a suitable device, you should immediately decide on the number of connected TVs. This is necessary for the right choice divider

To begin with, such a device should be firmly fixed on a flat vertical or horizontal surface. Only after this proceed with the actual installation. Actually this method antenna cable extension is similar to the previous one. As in the first case, it is necessary to use two f connectors screwed onto the ends. After which we connect the wire coming from the antenna to the input of the splitter, and connect the piece with which we are going to extend the line to the output. In fact, this is the same f connector only with the possibility of further branching.

That's all the information on how to extend the antenna cable. If, in your opinion, the article seemed incomplete and you are looking for other solutions to the problem, then I can easily supplement it, but in my opinion these are the main and most simple ways solving the problem. In addition to all that has been said, I suggest, for general self-development, to read an article about this, since this question arises quite often when rearranging furniture in an apartment or moving. For clarity and reinforcement of the material, I suggest watching the corresponding video.

Often in everyday life, many are faced with a problem: how to extend or restore a broken electrical cable or wire, in cases:

1. When you drilled or cut with a grinder wall or floor, and at the same time accidentally cut, laid in the wall and not visible to the eye electrical wire or cable. In this case, as a rule, sparks are visible at the site of damage and it turns off or knocks out. In addition, sockets and lighting that were connected after the damaged section of electrical wiring stop working.
2. It often happens that one or two wires break off installation box under a socket or switch, and the remaining length is not enough to connect them.
3. But it happens I need to move the socket slightly higher or closer to the connection points of electrical appliances.

You should know that the most the best option repair of damaged sections of electrical wiring will completely replace the damaged section from distribution box to the outlet or switch. But this work often requires gating and damage to finishing materials - tiles, wallpaper, decorative plaster and so on.

Some people connect damaged wires or cables by simply twisting them together and then wrap it with electrical tape.

But doing so is neither correct nor reliable.— due to the lack of reliable contact at the connection point, over time the twist oxidizes and begins to heat up!

You can restore or extend the electrical wire yourself , here it is important to remember that splicing is permissible when only wires from the same metal are in joint contact with each other. Only in the terminal block is it permissible to connect copper and aluminum conductors, since in it the wires do not directly touch when connected. In other cases, do not twist copper and aluminum together or press them together, since these two metals, when in contact with each other, begin to oxidize and the electrical contact disappears over time.

If you have electrical wiring in the switchboard is connected to RCDs or differential circuit breakers, which are triggered when current leaks from the electrical network, then it is necessary to very carefully and reliably isolate from each other not only the phase and neutral connections, but also the grounding conductor.

The best option would be to use heat shrink tube, which is first put on the wire, and after the wires are connected or extended, it is put on the junction and heated with a lighter, gas burner or a special hairdryer.

When heated, the tube contracts and seals reliably.

Electrical cables with a cross-section of 4 or 6 square millimeters on electric stove connect using soldering.

If one wire or two broke off in the wiring box for the installation of switches and sockets, but there are at least 1.5 centimeter ends left, then I advise you to extend the wires using a terminal strip (on the left in the picture below), strip the wires, insert them on both sides one at a time and tighten them with a screwdriver. Fast and reliable. But if there is not enough length, then you will have to break the section up to the box to extend a new cable section to the socket box. The connection procedure is similar to restoring a broken cable.

Welding of cores is carried out using a special factory-made apparatus.

Always connect two cables according to the corresponding core colors. This will help you correctly connect the grounding conductor on the outlet.

Step-by-step instructions for restoring a broken or cut electrical cable or wire.

1. IN panel houses The easiest way is to pull the damaged cable out of the channel and replace it with a new one from the socket to the junction box, because the electrical wiring in the panels is stretched inside pipes - gating not required.
2. In other cases, it is necessary to break a section of the wall along the cable or wire at least 15 centimeters in both directions and with a reserve of depth so that the insulated connection is hidden in it. Attention be careful, do not damage the cable again.
3. After that cut and clean, but at different distances, so that the exposed connections are not opposite each other.
4. We put on cambrics or heat-shrinkable tubes on wires of the same cross-section and metal as the damaged area. We connect them together using welding, crimped sleeves, soldering or self-clamping terminal blocks.
5. We stretch the heat shrink over the exposed areas of the connections and heat it.
6. We take high-quality electrical tape with good elasticity and stickiness and rewind each wire individually, if you did not use heat-shrinkable tubes. Self-clamping terminal blocks have good electrical insulating properties, but it still wouldn’t hurt to additionally wrap them with electrical tape at the connection points where the solution could get inside the electrical terminals.
7. Observing

In this article we will talk about how to extend the wire at home. As a rule, many people sooner or later encounter this problem. Nobody knows how to fix it, I decided to remove all the questions and do it for you detailed description. And talk about all the situations and ways to get out of them.

How to extend a wire: basic methods

Here we will talk about the simplest extension of wires, when there is full access to the wire and the cores of the conductors are made of the same metal. Such methods are suitable for both copper and aluminum wires.

Remember, build up copper wire with aluminum, you can only use a special terminal.

Read the classification of wires, not everything can be extended.

And so, here we have discussed the main methods with you. Watch the video, it will be even clearer to you.

Now let's talk about situations that may arise. Standard methods are good, but you need to be able to get out of any situation. I’ll tell you about all the situations.

Wire extension: everyday situations

A vein in the wall broke

If this happens, you must decide whether there is enough wire to connect everything. If there is enough, then we use any method that you might have seen before. If it’s broken so you can’t get under it, you have to break the wall and carry out all the actions there.

How to extend cable in water

This situation arises in cases where it is necessary to lengthen a section of cable laid in water, for example: a wire for submersible pump build up. Here you will need heat shrink tubing. We do everything only as shown in the picture. This method is suitable for underground cables.

Remember, you can heat it with a lighter, but make sure that the tube must fit tightly onto the wire.

How to extend a wire or cable to power powerful electrical devices

In this case, only one option is suitable - soldering. Don't even look at others - it will only bring trouble. Powerful electrical appliances include: air conditioning, electric stove, etc. The conductor cross-section should be (4mm).

How to extend a cable or cord of low power

For example, if you decide to extend the microwave cord, washing machine– throw this idea out of your head. After all, if you connect it incorrectly, there will be big problems. And you can mistakenly connect the grounding with the phase. In this case, it is easier to stretch the wire under the baseboard, and safer.

Increase the length of the temperature sensor wire for heated floors

Initially, read the instructions for it, if there are no problems, use the terminal blocks.

How to extend twisted pair

In this case, there are no problems, but remember, you need to build up each vein separately. Don't forget to carefully insulate the wire extension area.

How to extend the wire of an LED strip

To do this, you will need to purchase special connectors; they allow you to gradually increase the wire for LED lamps. Other methods and materials will not suit you in this case.

Interesting article: ABS cable description.

In this article we will look at several ways in which you can extend your Internet cable. With your own hands (using twist) and without additional devices, or with minimal costs (using an adapter). Using the instructions in this article, you can also extend the network cable that you use to connect your computer to the router, or for other tasks. Not just the cable that your Internet provider installed into your home.

Most often, there is a need to extend the Internet cable that comes into our house or apartment from the provider’s equipment. Please note that we are talking about cable. If you have, for example, fiber optics, then the solutions in this article will not work. During the repair process, when rearranging furniture, or moving devices, it turns out that the Internet cable is short and does not reach our computer or router. In this case, there are not many options: adapt to the length of the cable, ask the provider to lay a new cable of the length you need (which they are unlikely to do), or just sharpen the Internet cable. What are we going to do now? But first, some tips:

• If you want to connect a regular network cable that you use to connect two devices (for example, PC with router), then perhaps this makes no sense. It is easier to make a new cable of the required length. This will make it easier and the cable will be more reliable. Since any connection and especially twisting is not very good. You can make such a cable yourself, or ask to crimp the cable to the required length in some store digital technology.
• Perhaps in your case it makes sense to install (if it doesn't exist yet), and not extend the cable and lay it through the entire apartment. And if there is desktop computers, to which the network cable is most often laid, then they can be used in the same way. You only need a Wi-Fi adapter, which I wrote about.
• If we're talking about specifically about the Internet cable connection, then you can call your Internet provider and explain the situation. What do you miss about the length laid into the house? network cable. Perhaps the provider will offer you some reasonable solution. For example, they will send specialists who will replace the cable free of charge.
• Internet sockets. If they are installed in your house/apartment, then consider possible options connections using these outlets.

If you cannot do without connecting a network cable, then it is best to use special connectors (coupler, joyner). If everything is done correctly, the quality of the connection will not suffer. I do not recommend using twists. They create additional resistance and this can greatly affect the stability of the connection. And ultimately on speed and ping. A computer or router may simply not see such a cable.

Extending the network cable using an adapter (connector)?

This method is suitable in all cases. Both for connecting the network cable through which the Internet enters the house, and for extending the network cable for a computer, TV, router, modem, etc.

These connectors look something like this:

They call him a joyner. There is simply an input for the network cable on both sides (for RJ-45 connector). The "mom-mom" type. To connect a cable using such a LAN connector, you need to crimp the cable on both sides into an RJ-45 connector. I wrote in the article how to do this with your own hands without a special tool. If you have a special tool (crimper), everything can be done according to these instructions: .

If you use such a connector to extend the Internet cable, then you can buy a second piece of cable in the store. It will be ready (with connectors). If the cable of the required length is not available, then this cable can be made for you. Ask around in stores that sell computers and other computer equipment.

Simply connect two network cables to such an adapter and you're done.

Let's say on one side we have an Internet cable from the provider, and on the other side there is a second piece of cable that we made ourselves or bought in a store.

There are slightly different LAN cable connectors - couplers.

With their help, extending the LAN cable is even easier and more convenient. No need to crimp the cable into the connector and no need special tool. Only a screwdriver.

Do not confuse these connectors with splitters. They have one entrance and two exits. And they are intended for other tasks.

If you need to extend the network cable for a computer, TV, router

When the network cable is not long enough to connect a computer, TV, another router or some other device from a router or modem, you can also use connectors. But don't forget that you can always buy or make more long cable, or connect the device via Wi-Fi. Perhaps in your case this solution will be more correct and convenient.

Of course, you can take two pieces of twisted pair cable crimped on both sides into an RJ-45 connector and connect them through the connector.

Using such a cable, you can connect absolutely any device that has a LAN input to the Internet.

We connect the Internet cable using twisting

I already wrote above that this is not the most The best way, which can be used to connect a network cable. The quality of the connection may suffer, or even not work at all. But if there are no other options, or you need to do everything urgently, then you can try.

Simply strip the cable at both ends and twist it color-matched. For insulation, use electrical tape, or heat shrink tube. Each cable must be securely twisted and insulated.

I did everything for the first time. The most difficult thing is to strip the veins and twist them. They sometimes break. First we remove the outer insulation, and then we strip each wire.

I think this can be done more accurately than I did. After the network cable is twisted, each wire must be insulated. I used heat shrink tubing. Insulation tape will do too. Here's what I got:

Believe it or not, this cable even turned out to work :)

Just be careful with it, the wires are very fragile without insulation. They are easy to break and the cable will not work. You can wind the cable lower so that the connections do not move or break.

Write in the comments what method you use to extend the network cable and how it works for you.
