How do you tryabva, you know, for the electric cabling in the apartments on tavana

All the owner of the dwelling ima repair is basic. Tova can be a second house, an apartment in a new city, a new private house or a veche in use. It is single from the stage for repairs and is connected to electricity. Most of the electricity is relying on the tavan. And here you have a lot of questions, how can we direct everything in a good way in accordance with GOST, joint ventures, PUE and other rules. Tazi article girth basic.

When is it appropriately cabled to tavana?

Montiraneto on the cable duct on the tavana, the concrete is perverted, but it is too high on the rough hearth putty, at least 6 cm or more, inevitably covered with heating and water supply, for some reason it is higher on the putty, up to 8 cm or more.

Underground cabled.

Time to repair almost a fault in anticipation of the presence of false tavans (voltage, drywall and other types).

Tavanno cabled at presale.

Distinguish in smeared and leveled, as tavane is lined from the bottom of the shoulder, the method is outdated and impractical in relation to price and functionality. It’s hard to install the naked body of the body, for yes, illuminate the flock in a good way.In kashchi, made from the darvo, it is ostensibly montir on the tavan and on the interfloor ridges, dori on the highway (one to each in a group in width), sometimes laying on the passage on the tavan or on the rude tavan.

An example for kabelavane on darven podtavan.

In the monolithic kashchi, it is carefully assembled, and not groan, according to the project, it is attached to the carrier of the colony, in which it is taken away all the right zhleb, vdlbnatini or on the other hand, violating the integrity of the structure.

FAQIs it possible to eat it for yourself? There is no ambiguity. Sweep the stoman concrete surfaces (stoman concrete products), for the sake of constructive features (painting on the tegloto and increasing on the jacost from the kitchen), destroy these properties when braddyavan, some can be brought to a tyahnoto srutvane. Do not rip channels into monoliths by securing their shoulders to cables or other materials. The only exception is to open the fasteners of the elements. Can the distribution of kuti and be sewn up with drywall, opnati tavani or other types of tavani? Yes, it is possible according to GOST R 50571.5. glasses of vrazki trebva Yes, you can access for observation for measurements and support, with an exception, follow the injections: ... direct through brewing, soldering or slinging testvane ... ". It is not advisable to edit other options, but for the sake of it, there will be no guarantees for quality, durability and safety.

It’s connected one by one from the beginning, meaning that access to the tazi kutia is open is not always necessary. Maybe it's safe to hide under a fake wall.The experience of the fitter was to help, che kutia, gradation into the stenat, dori and open access in time for subsequent cosmetic repairs, often cover under tapeti or a layer of mazilka. Open the door itself, leaving the invoice behind externally cabled. It’s such a tryabva and isolate all the edges. Nai is convenient and safe to start for insulation, e.

Method for mounting on a cable - in corrugated or in sheaves?

And two methods of resolution, but it is considered in sheafs that it is very limited. Tosi's answer is controversial and unclear both for the client and for the installer. It is necessary to protect yourself and all of this from a visible dot on the PUE, SP and GOST regulatory documents. In Joint Venture 256.13258000.2016, which is somewhat appropriate from PUE, ima clause 15.8.Toy kazva: “Funds for treshni groupi Treabs are changeable: skriti - in special channels for building structures, fences; opened - in electrically pervaz, cutia, etc., with a certificate for compliance in accordance with GOST R 53313 ″.

There is one more position in the tov joint venture - 15.5. In it, here is a case: “In protecting the building structure from non-flammable and light materials (group G1), it is irreplaceable monolithic laying on group gratings in roaming on walls, barriers, tavani, under mazilka, in preparing a layer on the hearth, twisted with a cable or conductors in a protective sheath”.

At the two points of the ima, there are two contradictory thoughts: "Tryabva" and "allowed." In the question, putting a dot on dot 1.1.17 on the PUE: “For this, pay a debt for the execution of the research on the PUE, think “tryabva”, “tryabva”, “Necessary” and derivatives from tyah.The thought is “allowed“ Meaning that the decision to apply this exception is forced (for the sake of limiting conditions, limiting resources, installing on equipment, materials, etc.) “. The option with an additional insulating sheath is not safe for the cable itself, but the client decides something is better for it. Now, let's take a look at two methods.

In the corrugated cable, I put it on the tavan on the monolith, on the top of the concrete floor, on the bottom and bottom, bend it along the wall. Toy e is divided into categories, species, color and mechanics. In accordance with point 6.4 of GOST R IEC 61386.1-2014, the following categories are different from the options for protection:

• Razprskvane on the flame or not razprskvane.
• With or without corrosion protection.
• The degree of protection against the penetration of solid particles or water is based on the IP index and is standardized in accordance with Ch. 5 and 6 GOST 14254-2015g.
• With or without flashing (the presence of a stoman cable in the cable is stretched out on the cable).
• Upper (from -45ºC to + 5ºC) and upper (from + 10ºC to + 400ºC) temperature limits in accordance with point 6.2 of GOST R IEC 613866.1-2014.
• Powerful or not - influencing the mechanical mu yakost.
• Resistant to electrical current (low conductivity).

The type of corrugated sheet differs from material to production:

• Polyvinyl chloride (PVC) e nai - known and evtin look. It doesn’t spread burning, but it’s not stable as ultraviolet light, for some reason it can be whiter and even decayed. Not all preporchva for using it openly. Usually it's color, but the manufacturer will produce other options (white, black, caffeine, beige or wood grain). Tova gofrirane crawled behind the cabal in the fence. The resistance to compression (yakost) is divided into 3 types - lek, medium and flat (350, 750 and 1100 N, respectively).Tova is determined by the possibility of mounting on a specific corrugated run into concrete, gate or drugade.
• Polyethylene - depending on the technology for the production of se, the corrugations are distinguished for low and high nalyagane. Those designations are cato LDPE and HDPE. Those sa are resistant to ultraviolet light, oil products and jelly, but sa fire hazard. Commonly those sa blacks, worms and blues. Tova gofrirane crawled out for relying on cables navn. "Tezhkoto" corrugated from HDPE all spouts with putty, and double-walled pipes can and will be underground. Blossoming usually occurs with blacks, oranges, worms, in a row blue. Compression stability is the difference between the two options - 350 and 750N.
• Polypropylene - similar to the previous type, made from polymer material. Resistant to external factors and not supporting the outcasts. Maybe it’s from crawling somehow in the fall, so and otvn (not stated in the UV treatment). Distinctive feature of its resistance to high temperatures (+115 ° C). Bloom often e syn. Ima options with high power, cost up to 750N. The trace of those who are supposed to be able to fill it with putty. Compression stability is the difference between the two options - 350 and 750N.
• Polyamide - used for protecting the cable from moisture. UV resistant and suitable for external installation. May be fireproof (installed indoors). Resistant to high temperatures (+150 ° C). The offer is in black.

Depending on the mechanics of the cost and the type of cable corrugations. In accordance with point 6.1 of GOST R IEC 61386.1-2014, parameterize the cost of dividing into stability on the head, impact, roll and rolled goods. Each category of ima has its own strength, but the main thing is resistance to blows. Divided by tag into following:

• A lot of leks - minimal resistance to impact (nei-niska price).
• Leka - weak mechanical yakost, but golyama gavkavost.
• Medium - Suitable for placing in a wall. Expensive for damage from summer and punching.
• Tezhka is a golyama of a debelin on a stenat and a losha gvkavost. Suitable for spouts in concrete construction.
• A lot of tezhak - nay - izdrzhliviyat and skjp option. It is necessary for laying in earth or in places with other mechanical filling.

PreferencesAcose spasvat rules for installation (under angle from 90º and without heating), the cable can be replaced by dory in a smeared wall.Prevention from corrosion, fumes, ashes, moisture and mechanical damage. all kinds of tavani and cables in the housing premises. lack of price e at the temple, chipped off when laying in packs.

The “in sheaf” method is installed on an electrical cable on a tavana through a slab on a conductor in a sheaf with a subsequent sleeving. Kolkoto on the golyam is a snopt, sensible for -chesto trebva and behold a fixer on a tavana, such a thing and no sagging. The installation of this is justified in accordance with the hearth of the regulatory documents and the very top of the incombustible surface. I'm arguing about the brands of cables that are suitable for the tosy method: VVGng-LS, PPGng-HF and NYM.

Installation in sheaves and without additional insulation. Advantages Simplicity and barzin on the installer. Appear on water pressure. Taken for installation in the house and construction.

Before installation, it’s good to have a surface on a monolithic putty or concrete floor and this is a treat with a fireproof and moisture-resistant mortar (for yes, they will hurry to bet - battles). Comrade's idea of ​​understanding tavans from izkhvarlyane on visible concrete particles on the surface and even more fun is attached to moisture. It is a prejudicial thing to appreciate the cost on the machine (for clarification - no more than 10A, for contacts - no more than 16A).

How do you try and find a cable, consummate and other materials?

For laying on the tavana, cables are used, which will ensure correct installation, according to GOST 31565-2012, section 5:

• VVGng (A) -LS is a low flammable cable with a PVC base, fire safety rating from category A and low emission LS (low smoke).
• PPGng (A) -HF is a polyethylene core (PE) cable and features similar to VVGng (A) -L.
• NYM is the German equivalent for the pre-made cables, it is in the round sheathing.

VVGng-LS PPGng(A)-HF NYM

Consumable include a 6 mm mounting dowel, self-tapping screws for doors and metal screws, staples for corrugated, metal or plastic bracket, platform with a shackle for a bracket, a dowel from a riben kost for flat and round cables, single- and double-sided tightening shangs, a bracket with dowel.

What tool is more needed for the job?

Tavannoto okabelavane iziskva follow the tools and consummatives:

• Rotary chuck with drill 6, 10, 14, 18, 20 mm and flat for concrete.
• A screwdriver with a tip on the screw and self-tapping the screw.
• Accumulator mounted pistol and consummation for it.
• Hand tools (screwdriver set, pliers, cutter pages, chuko, roller shutter).
• Gloshlayf (mill).
• Stenen persecuted with an industrial prahosmukachka for okachvane along the stenite.

Sometimes you work with a percussion drill, a mounted gun, a grinder and a wall chaser, and you should use your personal means: eyeglasses, depending on the conditions for work (opening or closing), a respirator and rakavitsi from the fabric, sometimes preventing awakening and burning out.

Typical electrical circuits for lighting and contacts

Installed on the electrical wiring in the apartment and private house grounds, a plan was drawn up according to the rules, some showing the final result - lamps, contacts, key, cutia switchgear, points on the storage (furna, boiler, etc.), line conductor. The toy marker is a general design on the stait, a subdivision on the furniture and domakinski uredi. Ako the area is small and decide and send it to the apartments with your own scoreboard, you can draw a simple diagram on the charter sheet. Tova e is a lot of good, otkolkoto and darzhish vsichko in the head of si.

The contour is simply drawn.

In the event of a small area, few floors, complex equipment, experience in design and installation, you can hire a specialist in design and installation. Ima and a friend of the opportunity - yes, take the project ready, send applications and send the exchange through special programs: Microsoft Visio, Dia, Splan. The layout of the project consists of an explanatory note from the designer, symbols, location on the lamp and switch, a system for leveling the potential and single-line diagrams showing the protective equipment on the hearth in the shield.

Here are the options for a typical plan with a designation definition:

Plan for tavanno clarification

1. For convenience, please connect the lamp with the number assigned to the switch.
2. Designation on the cutia distributor.
3. Hanging lamp (sconce).
4. Determine the country on the gate to the gate.
5. Polyley.

Finishing at origin

Indication for high on the end of cooking under.

Location on the highway from the vgraden wall (number sa markrani in cherveno).

1. Specification for switchgear cuties for contacts.
2. Positioning Directly on the wall between the cables from the point to the cut and protect the panel.
3. Determining the boundaries of the trabi prez walls.
4. Broyat on the core in the cable.

Plan for location at low current points

1. UTP - sockets for Internet conductors and Wi-Fi points.
2. TV - TV cable sockets.

Scheme for leveling on the potential (grounding and connection of the main grounding bus for all pipes, cuties from metal equipment).

All electrical elements on tavana - pluses and minuses, compare value and practicality

No fixed price or price list for installation work. Get out of your way and get in touch with the population. Vvv Voronezh and to Moscow - more than 100,000 rubles. You can, yes, determine the differences in the price of a percentage of the same for determining the type of work. For example, a price for a single meter for a cable, put in a corrugated, e from 20% for -skjp from a sheaf. Distributor of cutia on tavana with 25% to -eutina from diverter of cutia in stenata. Ima is different in price for kabelavaneto in kutiya: skjpo - zavaryavane; average in terms of price, quality and compliance with regulatory documents - pressed with a heat-sealed pipe; nay-evtinata and contradictory e vrzkata with tag on WAGO and chatter vrzki.

Any installer needs more experience and make sure the installation method is convenient.The main repair of this perversion will last for many years and the trembling and this ima foresee that it will be useful just now. Not a warranty for long term service. By -skjpi in work and from the price of material, repair it is distorted, foreseeing it all in the future - dlgiyat exploitation belly.

Tavannoto kabelevane e nay - convenient type of installation and on-natatshna work. They gave it in corrugated or in sheaves, with some kind of cable, with limited access to the kutia distributor or not, but pervert the work yourself or with the help of specialists - it's up to you. The information in the tazi article is helpful and you will take the right decision.
