Carried out is better than copper or aluminum. Mіdnі droti for carrying out - a baganka or nebhіdnіst

⁰

Today, we are actively vikoristovuyuchi electrician (scream), it is simply inconceivable for ourselves without the head dzherel of our butt and we don’t give a damn about the respect that it will come to us at the booths on the drots, accepting it as a tribute. Tim is not smaller, the darts do not only go up to the call of the house, but they serve yoga to the skin from the middle rosettes. For these purposes, the wiring itself is victorious, yak, at your own hand, there are different types. Maybe aluminum will be the most popular among them.

I want operational characteristics aluminum cannot be called ideal for vikoristannya as wiring, prote, in a leather apartment, which is already conditioned by the features of the metal itself, out of the very material itself.

Advantages of carrying out for aluminum

The fact that aluminum itself, not being the standard of a hundred percent of electrical wiring, is more important in its capacity. living booths, enchantment with the same yoga over other metals

Small wag. This is especially valuable, if it is necessary to twist the cable from a great number. For the very same reason, aluminum is important to use in order to lay power lines.
Great is the breadth of that accessibility of metal, which is amazing for its cheapness.
Oxidation stability. However, here it is necessary to guard for an open air, for the smallest contact of oxidation, there will be a mitt, so that we do not threaten the dart in the middle of the cable insulation.
Spetsіalna zakhisna plіvka, yak utvoryuєєєєєєєє on wires, schob save її vіd oxide reaction. Plivka zdatna vikonuvat its function richly rokiv. However, similar zahisny zasіb є weak conductor strum and yogo passage can be difficult in quiet places, de cables require zadnannya.

Nedolіki wiring for aluminum

However, shortfalls, like aluminum in pairs with other metals, greatly obscure this transcendence.

A high-pitched electric opir, which is a powerful aluminum, is applied to this victorious station as electrical wiring in the living quarters of the subsistence farm. Depending on the rules for the operation of electricity, wiring with a transverse span over 16 square millimeters is allowed. To this, it is important to carry out the great comradeship, which can be called a good look.
High building before heating through great opirnist, as it increases when oxidized through cold smelting, in addition to the weak conductivity of the struma.
Frequent weakening of contacts through deformation of the cable through periodic heating and cooling.
The high krykhkist of the aluminum dart, as it can signifi- cantly be seen through parts of overheating, to change the term of the wiring service. Term її safe operation to become no more than twenty-five years after the end, which will be replaced in the general language order.

Rules for the operation of wiring for aluminum

In this manner, it is possible to make visnovoks, so that the wiring in the living room for aluminum is not one of best options. Tim is not less, she is quite agreeable with the pre-trimannian singing vimog:

Vykoristovuvat provіd cross-section of any not less than 16 square millimeters.
Close the okremі parts, vicorist special zatisknі contacts. In addition, leather from them is guilty of buti processing with special oil, which includes oxidation. Zavdyaki such a work can reduce the riven support, so that the heating of the wiring is not possible.

Carried out from midi and її transfers

The middle wiring can be used as the most suitable for use in living quarters, the shards will be richly safe, and the simplest in operation. Age for midi is less typical nursery opir. And it means that the wire is made of midi with the same peratin, that it is aluminum, you can skip more struma. Takozh midna electrical wiring:

May have a high resistance to a physical inflow (importantly zlamati zginannya);
May is a great term of appurtenance;
Її strum-conducting power does not become less during the oxide process.

Note that copper oxidizes just like aluminum. However, the spit, which settles on the midi, does not cross the passage of the struma, the shards easily crumble. More strongly oxidized midi may become less due to high temperatures.

In this way, you can make a visnovka, which is more safe and secure for the living room with an electric jet to build an electrical connection from the midi. Prote is more important than the majority of the population so continue victorious in their apartments aluminum wiring through її low varity. I, more than a little, without respect on the street, will be able to secure the best and not the least secure way of supplying the electricity of your life.

What is better - midna chi aluminum wiring? The food often breaks down among fahivtsiv and cross people, as they plan to change old darts into a booth, apartments or offices. In order to make the right decisions, it is important to know the advantages and disadvantages, the rules of operation, as well as the main differences between copper and aluminum switching.

Aluminum wiring may be the following:

Small mass. This particularity is important when installing power transmission lines, the length of which can reach dozens, or run hundreds of kilometers.
Availability at a price. When choosing a material for conducting a lot, someone should be guided by the variety of metal. Aluminum may be less obvious, but I will explain more low price virobіv іz thogo metal.
Resistant to oxidative processes (relevant for daily contact with critical exposures).
The presence of a smelter. In the process of exploitation, a thin coating is formed on the conductors of aluminum, which removes the metal from the oxide processes.

Aluminum May and a number of shortcomings, it is necessary to know about them:

High pitome opir metal and schilnіst to heating. For reasons of reasons, it is not allowed to block a dart less than 16 sq. mm (for reasons vimog pue, 7th edition).
Weakening of contact connections through parts of heating during the passage of great ambition and distant achievement.
Plivka, as it appears on aluminum dart upon contact with repeats, may damage the conductivity of the strum, which creates additional problems in the areas of production of cable products.
Krykhkist. Aluminum darts break easily, which is especially important in case of frequent overheating of the metal. In practice, the resource of aluminum wiring does not exceed 30 years, after which it is necessary to change it.

Rules for the purchase of midi and aluminum

There are situations, if it is necessary to replace only a part of the wiring or add (transfer) a sprat of sockets near the apartment. Such a situation is blamed for nutrition. To avoid increased heating in the areas of combining copper and aluminum wiring, varto vikoristati offensive methods switching:

Examined methods of connection can be stopped for the connection of wires, various metals(Not only midi and aluminum). Such vikonannya guarantees high rіven safety and the possibility of uniqueness of potentially unsafe twisting. Ale varto remembrance about the importance of periodic re-verification and broaches of bolted connections and terminals, even if the stench may weaken the authorities.

What material to carry out better?

Now let's take a look at the report, which wire is better than copper or aluminum. For whom the mind has appeared impersonal stereotypes and oman, we will talk about yaks below:

Durability. It is important that the term for the life of the middling dart is greater than that of aluminum. Tse Hibna thought. If you look into a special cable, you can reconsider that the resource of cables for both types of metal is identical. For windows with single insulation of wines, set 15 years, and for underwires - 30.
Flexibility to oxidation. Zastosovuchi cable for aluminum, varto memory about yoga stability to oxidizing processes. Even at school, they told us that Al (aluminum) is a metal that actively interacts with sour, through which a thin layer of spit appears on its surface. The rest protects the metal from the distant decay, but worsens its conductivity. How to isolate provіd vіd dovkilla, the risk of oxidation processes is reduced to a minimum. The peculiarity of the remaining field is the reduced capacity of the contact connection between the two wires and the removal of the oxide from the metal. In addition, the special oil turns on the aluminum contact with the necessary damage.
Mindfulness. Mid-wire vvazhayetsya mіtsnіshoy i zdatna vytrimuvat bahatorazovі zginannya. It is written in the GOST that it is wired, chimed from the midi, 80 lines are to blame, and 12 for aluminum.
Vartist. The price of drotu for aluminum is 3-4 times lower. Ale, when choosing, it is important to remember that the middle one with a peretina of 2.5 sq. mm is invested in a strum of 27 Amperes. Yakshcho vіddavati perevagu aluminum wires, comradeship drotu may become 4 sq. m. mm (nominal strum 28 Amps).
Opir. Depending on what to choose - aluminum and honey darts, varto vrahuvati rіzny petomy opіr. For midi, the parameter should be close to 0.018 Ohm * sq. mm / m, and aluminum - 0.028. Ale varto vrahuvati, scho the deep ground (R) of the explorer to deposit not only according to the chosen parameter, but also according to the area of the explorer. Yakshcho vrahuvati, for that purpose, the need to zastosovuyutsya aluminum darts a bigger cut. The greatest opir is blamed in the misfortunes of the day, but when you look at the future, you can not be afraid.
Ease of installation. It is important that the construction of wires from aluminum is more complicated. Tse is relevant only for the obvious joint wiring, twisting path. In times of zastosuvannya kіnets, klemnikov or bolts such a problem falls.

For the sake of respect, the meritorious situation that is being conveyed. When combining midi and aluminum at the contact point, different processes are used, through the overrun of which the opir is increased. As a result, the stick of two darts is overheated, the insulation collapses and the risk of borrowing increases.

The peculiarities of all metals are examined more, a different petome opir can be seen. In addition, a lot of vicarists are not “pure” metals, but their alloys, which also produce a support to change the parameter. In order to get rid of problems in the future, it’s better to correctly throw the darts and move them out of their twist.

At the end, we will bring some joy, which may be insured during the organization of the wiring:

At the time of independent design of the wiring in the booth of the apartment, it is better to choose the middle droti. With a small pererizі, the stench vitreous more strums and more stiykі to parts of the death. Not less important moment- About `em. Medium darts compact, which makes the strobe folding process easier. For example, when connected to a power supply of 7-8 kW aluminum wire the mother's fault is about 8 mm. At the cable three lived that plus braiding. Through war, the overhead diameter becomes close to 1.5 centimeters. For povіvnyannya mіd mozhe perezіz 4 sq. mm, and zagalniy diameter - no more than a centimeter.
When the socket is installed, follow the tri-core cable, іz grounding rod. Width of sockets in pіdlogi - 30 cm.
All the wires have been harrowed for one pair of wires (there are more aluminum stinks). The best option is to submerge the lancet on the sprat line. For example, through one machine the bathroom of the room is lived, through the second one - lighting, through the third - the kitchen and so on. Peretin drotu for kitchen and bathroom can be 4 or 6 sq. mm, and for light fixture - 1.5 or 2.5 mm.

Find a better place in old apartments, dismantle the aluminum, and save your resource and require a replacement. Carried out with a 2.5 sq. mm peretina shows a voltage of no more than 20 Amperes, which is not enough for modern electrical devices. In addition, the insulation of wires over time loses elasticity and gradually collapses. In such a situation, the only solution is to replace the wiring with copper wires.

Report on why varto replace aluminum wiring on the midway near the old booth, marvel at this video:

Podbags

Which one is better? From the positions of operational capacities, the most beautiful is copper. As it turns out, aluminum darts are cheaper. And here it is important to praise the solution - save on your safety.

It is impossible to find a house without electricity in our capital, it is light to come near all apartments and houses. In order to determine how to carry out a shorter copper or aluminum, it is necessary to look at the characteristics of the two materials and conduct a comparable analysis.

Aluminum wiring

The Danish type of wiring is wide-width in living quarters and apartments at the edge of the country for hours in the SRSR. Zustriti aluminum can be done at once, for any booth older than 15-20 years old. Tse pov'azano z such parameters alloy, yak:

small vaga;
cheapness.

So, as aluminum is important less midi, it is more likely to stop when laying power lines, which allows you to change the focus on the support, and to save on their preparation of installation. Zgidno from PUE during installation new lines Do not block aluminum cables with span less than 16 mm2. Don’t throw off cheapness and cheapness, to that the cost of money is more expensive.

Minusi

However, navit yakіsny aluminum wire may have more minuses, lower pluses. Until the negative moments, we can say:

less electrical conductivity, lower in midi (difference in 2 times);
building is oxidized upon repeated contact (as a result of oxidation, a ball is formed on the surface of the rod, which does not conduct electric strum, which changes the korisny reparation and zbіshuє opіr);
a smaller term of service (become 20-25 years, after which a sharp increase in fire resistance through oxidation and further heating of contacts);
weak mechanical strength (after a few virgins aluminum cable easy to break);
installation foldability (ensure the necessary wiring to be carried out in the right direction, choosing cables with a larger span, with which it is not handy to work. Such cables are only produced as single-core).

Please! You can change the quality of aluminum to evil, for which, when buying in a store, try 4-6 times to bend the drіt, as if the surface of it is covered with cracks, it means that the drіt is crooked and it will be important to work with it. Zrozumіlo, what better way to move in such a product.

Mid-wire

When buying a budinka, an apartment, you should choose the type of wiring. However, please keep in mind that, having replaced the wiring in the apartment, you have not yet taken away the superfluity and the building of the great attention to the mesh. Don't forget what input cable from the descent shield to the apartment near the old apartments, the windows are made of aluminum. Next replace tsyu dilyanka, even її conductivity now weak spot new lines.

Advantages of copper wiring

Alignment of the parameters presented below with the parameters of aluminium, allow correct choice nadali. Mіd, as a material for electrical wiring, may have a number of advantages, which can be considered:

good conductivity (after the oxidation of the smelting on the surface does not cross the passage of the electric jet);
term of service is 50 years;
high mechanical strength (lived easily visible twisting and twisting up to 10-15 times);
ease of installation (promislov_styu vypuskaєtsya kіlka vidіv darіv with different parameters and veins, with which you can manually work).

The minus of the home line is midi, sung, one is the price, however, if it is necessary to fix the wiring, let's take care of this material.

You can get darts from zinc alloys, covered with medium sawing, at the budіvelnih shops. The stench is cheaper, lower midi, however, the characteristics of the materials are delivered to the darts from pure midi.

In case of failure, koshtiv are better than vikonati combined wiring, socket group okremo power middle wires, roaring the struma for great strength, and the lancets of the visvetlennya are aluminum. However, let it be on the vase that the aluminum and copper joints are less likely to be wound through special clamps or good pads, as if they pass the direct contact of the midi and aluminum, which results in a stronger oxidation of the rest. Through the oxidation stick, the growth of the opir contact grows, and the result is heated and burnt.

Having looked at the characteristics, it is easy to make a visnovka, it’s better for vikonannnya assembly robots to vikoristovuvat mid, prote, if necessary, you can vikonat a line and aluminium, the axis can only be followed by a retelnishe. To choose the next type of wiring is necessary for the improvement of electrical safety, even if it is to lie down, as long as it lasts for a long time without the need to install fahivtsiv.
