How to choose and install concrete pillars for electricity

Electricity is already a huge amount of time is an important and integral part of the comfortable existence of each person. Well, in order to ensure that this resource can be delivered to every house and every apartment without fail, you need to take care in advance of high-quality and reliable installation of electrical networks by air from the transformer substation directly to the consumer. It is for these purposes that such products as concrete electric poles are intended.

Advantages of reinforced concrete products

Poles of this kind are supports for the construction of overhead power lines (PTL). Wires are attached to them.

Products of this kind are of three main types:

• Metallic;
• Wooden;
• Reinforced concrete.

To date, the most popular are concrete pillars for electrical networks.

Such popularity of reinforced concrete structures due to the following advantages:

1. Reinforced concrete from other materials used as power transmission towers is distinguished by high performance indicators:

1. Resistance to corrosion processes;
2. Resistance to destruction;
3. High resistance to environmental influences;

Note! Reinforced concrete electrical supports can be operated at temperatures up to -55 degrees and in conditions of the strongest aggressive environmental effects.

Most often you can meet with supports made of reinforced concrete with a cross section of round or rectangular shape. The manufacture of such products is carried out from concrete class B30 according to GOST 26633-91. In the role of aggregate for the manufacture of concrete pillars, granite rubble is used, which has high strength and frost resistance.

The most common type of power transmission towers made of concrete are single-rack products of intermediate location with metal plumb lines. But for arranging high-voltage transmission lines, they also use reinforced concrete anchor-angle supports with tie rods.

Some features of installation

The installation of reinforced concrete structures is a procedure involving the observance of certain conditions and rules:

1. In the production of works should be taken into account the following parameters:

1. Natural landscape;
2. Wind load on the structure;
3. Intermediate distance;
4. Traffic density (if necessary);

Council If during the installation it is necessary to drill a hole in the product or shorten it, then such methods as diamond drilling of holes in concrete and cutting of reinforced concrete with diamond circles can be applied.

For the arrangement of power transmission lines and the supply of electricity to the suburban area, reinforced concrete structures such as SV95-2, SV105-3, SV105-5, OPSV, OGK, SCC, etc. are most often used

When choosing these products, the question of how much a concrete pole for electricity costs is not fundamental, as long as the design is of high quality, reliable and durable.

Stages of installation

High-quality installation of concrete pillars for electricity includes the following steps:

1. Product selection depending on parameters such as:

1. Purpose;
2. Location
3. Electrical equipment;
4. The method of laying power lines, etc.

Installation instructions do-it-yourself stipulates the following work:

• Marking territory;
• Drilling holes;
• Installation support with the use of specialized equipment;
• Installation of electrical wires.

Marking territory and drilling

Competent installation is carried out in accordance with the specialized installation technology. The first step is marking, during which the required number of concrete columns and their location is determined. These calculations are made in accordance with the characteristics of the terrain itself, the parameters of the soil and the level of load.

After the marking has been made, proceed with the drilling process, strictly following the marking made, taking into account all the features of the soil on the site.

Note! At this stage, special equipment is used, representing earth and telescopic drills placed on the vehicle platform.

Mounting support

In places prepared in advance, installation of power transmission lines supports is made using a manipulator.

Before proceeding directly to the main works, it is necessary to make the control:

1. Inspect the product for damage;
2. Check the dimensions of the electric concrete pillar;
3. Reconcile using levels and plumbat.

Fixing the product in the drilled holes is made using a concrete solution.

Council To ensure strength and reliability, additional props from metal or reinforced concrete can be used in the installation process.

Further, according to the technology, metal structures are installed under the traverses and insulators, on which special clamps or pins are provided for fastening.

Traverses do not conduct electric current through themselves, but serve only for fastening wires of power lines. Such products may have different dimensions depending on how many wires they will hold.

In the production of traverses covered with anti-corrosion coating, and in the process of mounting on such products are installed specialized covers, protecting the structure from atmospheric phenomena. The final stage of work associated with the installation of wires.

Finally

Installation of reinforced concrete pillars, which will serve as supports for power transmission lines, is simple, but involves the use of special equipment. But in the end you will get a reliable design, which will uninterruptedly supply electricity to your suburban area for more than a dozen years.
