How to connect wires from different metals

The answer seems to be simple, but nonetheless often connecting the wires, electricians and people who do electrical work on their own, violate the basic requirements for electrical contacts. What does this lead to? At best, to burning wires at the junction, at worst to ignition and a large fire. To prevent this from happening, later in the article, the main ways of connecting wires during electrical installation work will be considered. Connection methods: -twist; -through terminal; -through clamp;
-bolded connection; -soldering; -through lugs. Connecting wires by twisting. This is the fastest and easiest way to connect one or more wires therefore it is used more often than others. If the wires are twisted correctly, when using them in a home network with a small load, they will last for a long time without any reminders. Frequenterrors when connecting wires by twisting. The most common mistake that installers make is to twist the strands of various metals (copper with aluminum). With such a compound, a complex electrolysis process takes place in the twist, which leads to the destruction of the metal itself. It is covered with oxides and potholes. All this leads to poor contact at the junction, and subsequently heated. In the end, the conductors simply burn from each other. This is accompanied by the smell of burning insulation, crackling, and sometimes fire. How to twist wires with different metals correctly. Find a small piece of tinned wire

and remove insulation from it. Next, fluff the wires and evenly screw them on the aluminum wire. With the help of pliers, with an effort to wrap around the copper conductor.

At the end,bend too much onto this twist.

Now copper touches directly with aluminum through tinned wire . And it will not give rise to electrolysis on different conductors. Connection through the terminal. The presence of terminals can also facilitate this work and ensure a high-quality connection. There are a lot of types of terminals, but they have the same principle. The photo shows two types of terminals, which can often be seen in different devices.

For example, in fluorescent lights, at the junction of the supply wires. Also these terminals are freely available and can be 10 pcs. and more in length. Having bought such a block, you can simply cut the required number of elements with a knife. Connect the conductors from different metals in the terminal is not difficult.First you need to remove the insulation from the end of the wires by 3-4 mm, so that the bare area does not go beyond the bounds of the terminal.

Turn off the screws until the wires lead to free passage, and having inserted, we clamp them.

You should not make too much effort, otherwise the fragile thread will" break ", because of which you will need to replace the terminal. Such a connection is quite reliable. With a current of up to 1.5 kW, it is free to do its job. It all depends on which terminal to use. Here is considered the weakest, using more powerful, the flow current can be increased. In addition to the option to connect the wires of different materials, the terminals can be successfully used to increase the length.This can be useful in the case when the wire in the box is so short that it is not enough to make a twist. This is where the terminal will help. The same applies to the broken wire coming from the ceiling to the lamp. This, incidentally, is a very common problem. Even if a little conductor still sticks out from the ceiling plate, the terminal will successfully help to extend it. Connection through a clip. Sometimes there may be such a hand, or a similar clip.

That problem with the connection can be solved with its help. How to make it clear from the photo.

After the screws are securely clamped, this entire bare area must be insulated with PVC adhesive tape. Bolted connection.Bolts, nuts and washers are always on They are at hand. Therefore, in the absence of clamps and clamps, they also fit.By the way, on large bolts, high-quality connections of powerful cables of large cross section are made, and this method is still successfully used in industrial enterprises. So, you need: -bolt of the required length, - nut; -three wide washers.

First, the puck, further, we can make ring pliers or just a pliers twist the conductor around the thread.

Need to bend over the movement of the thread. That is, so that when tightening the nut, the loop does not expand to the sides. A washer between two conductors will prevent them from touching and will prevent the electrolysis effect that destroys metals.

Soldering. Soldering is considered the highest quality, since the resistance in this place becomes minimal. Some themselves are missing twists in the boxes, thus improving the connection. But this can be done with copper. And aluminum is not well soldered. Yes, you can apply different acids and additives, but they, as a rule, destroy the compound themselves over time. But with rosin and tin, you can tin the copper conductor. And then quietly twist it with aluminum. The connection will also be pretty good.

Tips. If you find such tips, it will be very good. This is one of the most reliable types of compounds. Insert the wires into the lugs, and clamp them with pliers,and after that we press down with a hammer and a tack.

Tips should be tinned, or you need aluminum conductor, wrap in tinned wire before you insert it into the hole of the tip. After the tips should be squeezed with a bolt and nut, and all isolated tape. Conclusion. Of course, now there are more advanced methods and devices for connecting wires, but they need to buy and learn, what extra money and time is running out. The old, good methods described above will be used for a long time, and will also serve for a long time faithfully. So why pay more?
