The electrical wiring may have two options, air and underground. For someone more acceptable the second option, but for someone it is not feasible because of distance and other conditions. Because most often, the owners of country houses prefer to choose air way for the laying of electrical wires from electric poles to their homes.

The Initial phase

It's Hard to imagine a cottage or country house without electricity. The organization of introduction of energy in residential building – it is very responsible, because the result depends on the reliability of power supply at home and, most importantly, its safety. Works on connection of private homes to power lines (power line) should only be performed by specialist companies, whose ownership it is. When choosing air routes for the laying of cable will need trubostojku. To input electricity to the site without this thing can not do. It is a hollow metal tube, which is designed for fixing and hanging of cables and wires.

Stick to the rules

The Rules allowed for such specialized rack mount and other equipment, including transmitting-receiving antenna. By the way, trubostojku to enter the electricity could be useful when underground method of liner. After all, if the distance from the ground to start construction of less than 2.75 meters, then you will also need its application. This is necessary in order to avoid accidental touching of wires, but only its length ensure the distance from the surface of the earth to enter.

More about

Trubostojku for input of electricity is a section of pipe, curved top, which are fixed on the roof or on the top of the wall of the house. From there it can go inside. In order to build trubostojku on the roof, use steel extensions. To the wall it is fastened with staples and screws. Through the end of the pipe are entered and displayed wires in the building, and out of it. In the literal sense trubostojku for input of electricity is the entry point of the cable into the building, where it will be placed next to energoprinimayuschikh devices.

Specific and primary purpose of this things, sometimes referred to as in the environment of electricians ‘goose», – asset protection, that is, in this case - residential buildings from any potential risks of fire, plus it is also a guarantee of reliable protection and content flowing through the power cable to integrity.

Finding a plot

If the distance between power lines and house more than 20 m, it is necessary to raise additional trubostojku for input of electricity, roughly somewhere in the middle of this gap. This will avoid breakage of the cable under its own weight or from environmental influences, for example from strong wind and other precipitation. Between the points last a special cable which prevents sagging of the wire. Conductor fastened to it with clamps. If you want the stringing of power cables above the roadway, then the height above the ground should be 6 meters and above. Over the roads for pedestrians are allowed from 3.5 meters and above, but in any case not below this value. Prohibited transaction through the trees and shrubs.

The Nuances of the air strip

A Special metal pipe riser is used both as a conduit and as a support used for fastening of insulators. Because to mount them to a much easier and simpler than the wall of the building. To attach and secure fit screws, bolt clamps or any other fasteners for the metal. Trubostojku to enter the electricity needs to be connected to the ground wire. From the surface of the roof the cable is not below a two-meter gap. Actually, as for the wires, then apply any kinds, corresponding in its characteristics to the requirements of external wiring.

Not departing from the standards

If possible, whether certain types of work to do yourself? Concrete example: you will not have any problems with the electricity grid, if their own be made trubostojku to enter the electricity? With his own hands the execution of it is allowed under condition of full conformity of the result specifications. This item is made of steel. If you need to input two wires, the internal diameter must be 20 mm, and the four leads – 32 mm. In order to avoid falling into the pipe moisture, the end should be bent down, in the literal sense is deployed in the form of a hook 180 degrees in the opposite direction, so it should look like trubostojku to enter the electricity (photo). The inside surface for corrosion protection is necessary to process the bitumen, but you can just oil paint. The edge of the pipe took a SIP should be cleaned with a file to eliminate burrs that can damage the cable insulation.

Selecting a electrical wiring

Before 1991, in order to carry out the input electricity to the area of the used wire, having the insulation (AC grade). But nowadays there is a sample designed specifically for the airthe cable. This instance is isolation, which is not afraid of even large temperature swings. He has another big plus: this cable is not stretched and when laying and does not require the presence of supporting cable. The purchase will not be forced to wrestle with because the wire is only represented in 2 forms: a four-wire and twisted pair. In addition, we should note another important advantage: for this type of cable in the sale is a lot of extra accessories designed for its connections with fasteners. This is a very convenient thing, not besides requiring no special effort at installation. You should pay attention to it.

Installation

Set trubostojku to enter the electricity can be 3 ways:

  1. Mounted on the roof of the building.
  2. On the wall.
  3. In a separate structure.

In the first case, the product is mounted directly on the roof, the pipe thus passes through the roof structure, and insulated from the back side through porcelain bushings. Switchboard in this embodiment, arranged inside the building. The complexity of such assemblies is the need for punching through holes in the roof and its subsequent sealing.

In the second case, trubostojku is mounted directly on the wall structure. Passing through the barrier, but inside it is included in the flap. There and arrange the primary distribution power lines at the facility. This installation option is considered to be more simple and safe, due to the fact that the power cord is routed through the non-combustible part of the wall.trubostojku to enter the electricity photo

And the remaining is considered to be the most common. Design consists of 2 columns, one for the power receiving unit switchboard, and the second – trubostojku to input electricity to the site. The design is mounted on the border of the territory and provide regular connection of electricity at the facility. With this method the entry point of the electricity is completely separated from the house. This explains its relevance.

Technical issues

Each of these options trubostojku is a separate engineering construction, with its own specific characteristics and compliance with respect to the objects. Given the above, you can highlight the main: trubostojku counter requires special attention to specific structural elements:

  1. Insulation of the connected cable.
  2. The Choice of insulators: porcelain, insulators and other systems ( including features of the object).
  3. Form the pipe. Bend to the desired angle depends on the mounting method, for example, in the wall it enters at an angle of 90 degrees with on energoprinimayuschikh equipment.

Details

Setting trubostojki to enter the electricity requires also to pay attention to additional technical specifics. Montaging the wall you need to consider the occurrence of the temperature difference, as it will lead to condensation of liquid from the colder air outside. In this case, it is necessary to protect the conductor from moisture. To do this, drill a hole in the bottom surface of the pipe in the place where her bending. For reliability and quality the choice of materials and the installation is best left to professionals. The correct entry to the house electricity is a guarantee of its uninterrupted flow from the energy source and distribution, affect the operation of all equipment and appliances. set trubostojku to enter the electricity

Reliability in the first place

If you are purchasing trubostojki, it is first necessary to study all the design nuances of the product. Not to be neglected, since the correct choice will affect the safety and durability of the selected instance. Information for the implementation of it and the installation can only give the professional. Because, the experienced master will take into account such factors as the risk of icing, wind load, and other factors associated with the stay of the construction on the street. And it should be noted that the cost of installing trubostojki the specialist is not so high, but the risks from self-Assembly in violation of the technology, have the ability to inflict much more damage.height trubostojki to enter the electricity

Preparation steps

The Beginning of the input electricity to the area – this is primarily documented in the project approval and permission after considering all the technical conditions in power supply organization. After “good” on the work plan from the aforementioned instance is obtained, you can hire a specialist who will perform the wiring according to the certified document. The input of electricity in private buildings involves the installation of all components of the internal network. Mounted meters and switchgear. Strictly speaking, a summing input to house electricity is performed by contractors.

Design trubostojku

Consider a situation when the technical conditions owner of the land had already been received and now need to connect the house to the network, but the height trubostojki to enter the electricity allows you to fit it into the landscape without spoiling the appearance of the site. In this case you can hire professionals whowill produce for you individual trubostojku, which will retain the harmony of your site, and will not be knocked out of it in a hurry. With all the technical specifications she will be fully fit. As a variant: perform trubostojku externally “Romeo” or in the form of abstract shapes, the master designer will mask the intervention of civilization and will not spoil the aesthetics of your vacation.

Setting up

During the establishment of electric lines in the house trubostojki you want to perform the vanishing (that is, to connect the pipe with zero lead). For this purpose, the so-called the gander is welded a metal bolt, positioning it close to the insulators of the input. Installed trubostojku will always be under load from the tension of wires of the branch. To compensate for this use the wire from a round having a diameter of 5 mm, of steel. Is attached similar to the support rings or bolts for this purpose is welded to the rack closer to the upper curve.

During the installation of trubostojku threaded steel wire rope or cable with a diameter of 3–4 mm for stringing using them the cables inside trubostojki. For easier pulling of the wires they are pre-wipe with any soft cloth, and trubostojku blow the inside dry with talc. After the cables stretched, the ends of the tube is filled with bitumen or closed by means of gaskets in the edges of Portland cement, water-resistant putty.installation trubostojki to enter the electricity

A few tips in conclusion

To the wall trubostojku attach with staples and screws. To do this, in concrete as in brick walls, especially to make nests for screws, like hooks under the isolators. Bolting, it is necessary to apply a stopping supplements, such as locknuts, spring washers, wire. This precaution definitely will not be superfluous, as mounted on the roof or even on the wall trubostojku will be prone to swaying from the winds, so that there is eliminated the loosening of the nuts. And, in addition, all bolting at the end of installation the input must be liberally lubricated to protect against corrosion technical vaseline or any other lubricant.
