For durabilitySV 110-5 (power line 98.16) reinforce according toGOST 23613-79 . As reinforcement, prestressed steel bars of class A-III, At-I, At-VI, At-V with a diameter of 10-14 mm are used. (non-corrosive metal for external hinges and embedded parts - bolts with which the products are attached to the foundation). The lower part of the product uses wire reinforcement with a reverse taper. Steel and concrete are treated with special anti-corrosion compounds.

Power transmission line poles made of reinforced concrete have significant advantages over other building materials (there are also wooden and metal poles). Reinforced concrete is not subject to destruction under aggressive environmental influences and does not harm the environment; reinforced concrete products are suitable for installation even near clean groundwater sources. High strength and resistance to the environment (climatic conditions, precipitation and chemicals in the air) make it possible to expose racks to CB 110-3.5 IV for poles of 10kV transmission lines for non-aggressive and aggressive environments of long-term operation (50-70 years), while the construction of poles do not require constant maintenance. The design and materials of the supports make it possible to operate them in an environment with an aggressive degree of impact in climatic zones, where the ambient temperature drops to -55 ° C, seismicity reaches 9 points, and wind and ice loads correspond to VII and V regions according to SNiP2.01.07-85.

Currently, energy construction is actively using power transmission towers throughout Russia, as they are the most resistant to extremely low atmospheric temperatures and aggressive environmental influences. Unlike a wooden lighting pole, reinforced concrete products do not rot in a humid climate and can be installed both in the city and along highways, railways, in mountainous or wetlands and forests. Compared to metal products, racks SV 110-3.5 IV for poles of 10 kV transmission lines for non-aggressive and aggressive environments do not require regular technical inspection, they do not need to be periodically painted or galvanized to prevent corrosion or oxidation - concrete is pre-treated during molding with anti-corrosion and water-repellent additives.

In the production of power transmission towers, we use the latest production technologies to ensure the high quality of reinforced concrete products and maintain the performance of products for many years. Our rack products SV 110-3.5 IV for poles of 10 kV transmission lines for non-aggressive and aggressive environments comply with all standards and requirements of GOST.

Structurally, power transmission towers are an elongated rectilinear figure - a rack. Embedded parts for clamps, traverses and fasteners for fixing wires are provided in the body of the structure. The lower part of the support, if necessary, also has embedded parts for fastening to the foundation and other structures that serve to increase the stability and bearing capacity of the supports (slabs, crossbars).

Installation of rack products SV 110-3.5 IV for poles of 10 kV transmission lines for non-aggressive and aggressive environments begins with laying out the details of the pole along the route for its further assembly. Assembled on the ground, the structure of the power transmission line support is lifted to the design position with the help of a crane and installed in a cylindrical pit with filling the voids with a sand-gravel mixture. In soils with low bearing capacity, the fastening strength is achieved by fixing the supports with crossbars and installing them on special base plates. For fixing guy wires in the ground, anchor plates or other foundation structures are installed at the design distance from the support in accordance with the project.

Energy construction assumes that the products of the SV 110-3.5 IV rack for 10 kV transmission line supports for non-aggressive and aggressive environments are made only from high-strength heavy concrete with a compressive strength class of B30. Portland cement is used as a raw material for this, which has increased strength, frost resistance, corrosion resistance and low water permeability. Granite crushed stone, which is introduced into the composition of concrete, gives products additional stability and resistance to low temperatures and high humidity. The frame made of high-strength steel compensates for the fragility of concrete and increases the elasticity of the structure. In order for the supports to be resistant to external influences, they are compacted by vibration, due to which air cavities are removed, and the concrete mixture spreads evenly over the entire cross section.

The concrete of the pillars of the power transmission line supports is reinforced with prestressed reinforcement to give greater strength to the products. Reinforcement in the form of three-dimensional frames is carried out from bar steel of classes A-III, At-I, At-V and At-VI. All parts of the products of the SV 110-3.5 IV rack for 10 kV power transmission line supports for non-aggressive and aggressive reinforcement environments and embedded parts are pre-treated with anti-corrosion treatment and coated with polymer coatings.

Like any load-bearing structures, racks SV 110-3.5 IV for poles of 10 kV power transmission lines for non-aggressive and aggressive environments are subject to strict product quality checks. Power transmission line supports should not have cracks, except for shrinkage cracks, the width of which should not exceed 0.2 mm. Sinks should be no wider than 20 mm in width, chips - no more than 20 mm in depth. Maximum deviations of the geometric parameters of reinforced concrete supports should be no more than ± 60-80 mm in length, section - ± 6 mm. Deviations from the plane of the rack should be no more than 15 mm in any direction. Reinforcement exposure is strictly prohibited. The thickness of the protective layer of concrete to the reinforcement should not be less than the design by 3 mm.

How to get to the production:

Racks reinforced concrete vibrated CB are designed for supports of overhead power lines. They have other names, such as lighting poles, or simply power poles. Our factory produces two types of CB racks, nine and a half and eleven meters long.

Racks CB 95 intended for high-voltage lines 0.4 ... 10 kV. If you need to connect a portable ground to these supports, then this can be done thanks to the conclusions of special contacts. During the repair and maintenance of overhead lines, this property of the SV supports increases the safety of work. Supports SV 95 differ from each other in the calculated bending moment. This parameter can be 2.0 tf/m and 3.0 tf/m. It is allowed to use CB racks both in non-aggressive and in aggressive environmental conditions. Design supports SV 95 designed in such a way that the rack has 4 grounding descents, which provide reliable grounding of the working fittings of the product. The strut CB 95-2, like the strut CB 95-3, has an upper end reinforced with prestressing reinforcement. At the end there is a steel plate that performs the functions of protection against destruction, increasing the service life of the CB support.

After stripping the finished product, metal end plates are welded to the four reinforcing bars of the SV support. A grounding conductor is welded to the mortgage loop and the bottom plate, and an outlet for portable grounding is attached to its end. If during the production of racks CB 95 the reinforcement is not prestressed, then end plates will be absent.

eleven meters racks CB 110 are also made from heavy concrete of B30 compression class. The frost resistance of concrete should not be less than two hundred cycles, and the water resistance index should be W6. For intended use in a hostile environment, supports SV 110 a protective coating must be applied to their lower part. It can be bitumen or mastic. This coating is applied directly in the factory to a length of up to three meters. Also, for aggressive environments, the diameter of the grounding lower conductor should be twelve millimeters, and the place of its welding should be protected with anti-corrosion varnish.

Installation of CB racks should be carried out only by qualified teams of installers. The supports are stored on a pre-leveled area, laying wooden blocks. The year of installation and serial number must be applied to each CB rack with indelible paint. The top of the support is lifted with the help of a truck crane, traverses are attached, a grounding slope is laid. At a distance of three meters from the ground line, a warning poster can be installed. Often mount special breaker cabinets. This is done in places where there is a risk of damage to the support by vehicles.

After preliminary marking, work on drilling the soil is underway. The depth of the hole will depend on the thickness and height of the installed SV supports, and its diameter should be twenty centimeters larger than that of these pillars. Next comes the actual installation of the racks. In order to achieve a strictly vertical position of the support during installation, it is placed on temporary struts. High-grade concrete is poured into the voids directly to ground level. After all the CB racks are fixed, it is necessary to make a control check of the position of each of them.
