Manufacturing features

Since the SV 95-3 supports have special requirements for strength and resistance to atmospheric phenomena, they are made of heavy concrete of class B30.

Thanks to vibrocompression, concrete is strongly compacted, due to which excellent strength indicators are achieved. The filler is granite crushed stone of a small fraction.

An obligatory stage in the production of reinforced concrete supports is the reinforcement process. For this, a strained wire with a diameter of at least 12 mm, made of steel, is used.

To increase the service life, the reinforcement must undergo a treatment procedure with special compounds that will protect it from corrosion.

Scope of application

Reinforced concrete racks are most often used for laying power lines. They can act as anchor and intermediate posts. They are used in both construction and renovation work.

They can also be used for organizing street lighting, laying telephone cables or SIPs, and so on. Resistance to winds and low temperatures allows the use of reinforced concrete racks in all weather and climatic conditions.

Features and Benefits

SV 95-3 supports made of reinforced concrete have the following properties:

• resistance to seismic vibrations;
• water resistance;
• resistance to low temperatures (can withstand temperatures down to -65°C);
• high strength;
• resistance to strong winds;
• resistance to corrosion and chemicals.

Vibration racks are versatile, as they can be mounted on soils with different acidity and any type. They are not afraid of temperature changes and harsh climatic conditions (winds, ice, earthquakes up to 9 points).

The design of the poles provides for hanging lighting equipment and wires, so the process of installing overhead power lines, lamps or other devices is quite simple and fast.

To install the supports themselves, heavy equipment is required, since the weight of the finished products is very large.

The supports can serve up to 50-70 years, while they do not need maintenance, and electrical work can be carried out without dismantling the racks themselves.

Unified support post SV 95-1 for power grid construction of 0.38 kV overhead lines. Reinforced concrete square bar used to support equipment of substations, industrial enterprises and the needs of industrial construction. Racks are applicable in the construction of workshops and auxiliary buildings. It is permissible to manufacture racks with an end face slope of no more than 1:10.

Racks are mounted in most types of soils in drilled wells. For weak and heaving soils, GOST 26071-84 provides for the embedding of racks in unstressed footboards (foundations) of a glass-type UB with a square section. The weight of the vibrating rack itself is 750 kg, so the delivery of such an oversized cargo requires the participation of experienced drivers. We have been completing energy construction projects for more than 15 years, we are trusted by clients in Ukhta, Magnitogorsk, Kemerovo, Voronezh, Yekaterinburg, Kazan, Smolensk, Moscow and Stavropol.

In fact, unified racks are solid pillars that require high strength, the ability to withstand the effects of environments, wind loads and equipment vibration. Modern energy construction is carried out only from special concrete resistant to electrocorrosion. Vibrated struts CB 95.1 are prestressed, square section, which is the most convenient for use in a fast pace of construction. The support on the base of the rack has an arm at both ends, in the case when the arm of the rack is made only on one side, the letter “A” is added to the marking.

The racks work in a vertical position, they are distinguished by high wear resistance, the ability to perceive large dynamic and vibration loads. Solid poles (as unified racks CB 95-1 are otherwise called) are produced in five standard sizes (according to series 3.407-102 v.1), which satisfy all the needs of substation construction. Rack lengths from 2.2 to 5.2 meters make it possible not to use other fortifications for their installation except for footboards, which are also designed in GOST 26071-84. The design of the racks includes two mounting loops for ease and safety of installation. Racks CB 95.1 are considered reinforced concrete products of a high degree of responsibility, therefore they are periodically tested for strength, rigidity and resistance to cracking. Manufacturers without fail give guarantees for the racks, their compliance with the working drawings and other requirements of the 3.407-102 B.1 series and other standard albums that define the working drawings of the power transmission line racks.

The equipment rack for the distribution of devices is produced with high-class reinforced steel (steel bars), hot-woven fittings made of steel A-I, A-III, A-IV, A-V. GOST and working drawings will tell you more precisely about the reinforcement of specific products. To pick up racks vibrated for power transmission line supports, you need to contact the manager by phone or on the website. Sale of racks and poles of power lines is carried out wholesale and retail with delivery to the gate of your facility. The company "Complex-S" also accepts orders for individual production of racks, poles, supports and other reinforced concrete products for energy construction.

Characteristics of the vibrating stand CB

GOST 26071-84 suggests special heavy concrete for the production of support struts SV 95-1, which is characterized not only by high strength M200 (B 20), but also by increased water resistance W4 and frost resistance within F100-200. On special orders, racks for X equipment are made with especially low permeability (capable of operating in aggressive environments) and special frost resistance (capable of withstanding temperature drops below -40 degrees Celsius). The universal operating conditions of the CB 95.1 racks have significantly expanded the halo of the distribution of reinforced concrete products for substation construction.

Product marking

The conventional designation of the racks is extremely simple: the type of the rack, the standard size and the letter “A” are indicated in the case when the rack has a head from one end. Additionally, the type of reinforcement can be specified. The marking of the racks is indicated on one of the faces of the product, at a height of 1.5 -2 meters from the bottom end.

For example, consider, SV 95-2 a(9500 x 165 x 240 mm), where:

• SV - vibrated stand;
• 95 - length in decimeters;
• 2 - standard size of reinforced concrete products;
• a - headband from 1 end.

Markings must be applied with indelible paint on the surface of each universal rack.

How to choose and buy the best concrete power transmission towers

All reinforced concrete used for the construction of power transmission lines undergoes a thorough quality control, since when laying the line there is a high responsibility, because any malfunction of substation equipment and its reinforced concrete foundations can lead to tragic consequences.

Deviations in the dimensions of the post should not exceed 10 mm in length, not more than 5 mm in displacement of embedded and reinforcing products. The surface should be smooth without sags, chips, shells.
