Quality that has stood the test of time

Ural Forest - a tradition of quality since 1959

Главная

Ural Timber Company (formerly Serov Energosokombinat) is a manufacturer of wooden transmission line supports and communication lines made of high-quality timber from the Urals. The company, founded in 1959, was the largest producer of supports within the USSR Ministry of Energy with a production volume of 150,000/m³ of transmission line supports per year.

In addition to its main products, the Serov Energia woodworking plant was the largest supplier of carpentry products.

USSR technology

The production process, which has been fine-tuned over the years, makes it possible to produce products that meet the requirements of GOST. The production capacity of the plant is up to 50,000 m3 of wooden power transmission poles per year.

ISO 9001:2015 standard

The products are certified by the Senezh Research and Production Laboratory for Wood Protection. The quality management system is certified according to ISO 9001:2015

Strict quality control

A multi-stage inspection system at every stage of production - from incoming raw materials to finished products. A regulated process for selecting reliable suppliers.

Well-established logistics

Proximity of highways and railway station, own railway siding, availability of river port in Perm. Delivery of supports to any region of Russia and the world.

OPTIMAL CHOICE

Need wooden transmission poles?

Nordic pine overhead line supports are recommended for use by RAO UES as the best solution for reconstructing obsolete power lines and constructing new ones.

major differences

How are wooden poles more advantageous than their reinforced concrete counterparts?

Economical

The weight of impregnated timber is four times less than that of reinforced concrete - this significantly reduces transport costs. Wooden How we produce the poles are 20-30% cheaper than reinforced concrete supports, and their service life is several times longer. The operating cost of quality-impregnated timber supports is lower than that of their counterparts made of other materials.

Easier to install

The installation of wooden poles does not require special machinery and reduces the number of workers on site. Wooden poles do not fear mechanical damage during transport, installation or operation.

Durable

The service life of wooden poles is at least 50 years. Wood can remain in waterlogged and saline soils without much damage to itself. The service life of reinforced concrete in such conditions is only 5-7 years.

Holds heavy loads

Wooden transmission poles can withstand strong vibrations and bending loads 1.5-2 times higher than reinforced concrete towers. This makes them more reliable in high winds and icy conditions. Impregnation makes the poles more resistant to fire.

No domino effect

Wooden transmission poles are held on the wires when they collapse, not taking neighbouring poles with them in a domino effect, unlike their reinforced-concrete counterparts. This significantly reduces the number of outages and simplifies repair work. Wooden supports are also recommended for installation in earthquake-prone areas.

Stable in soils

Wooden supports are not susceptible to buckling in northern soils, due to their complete freezing into the ground. The forces of adhesion with the rock counteract the freezing bulging forces.

Expert judgement

Our supports are fully compliant with Rosseti's requirements and standards:

GOST 9463-2016 (Round coniferous timber - Technical conditions);

GOST 20022.6-93 ("Wood protection. Impregnation methods");

GOST 20022.0-93 ("Wood protection. Protection parameters");

International Standard BS 1990-1:1984.

TU 02.20.11-001-96502166-2019.

The right technological process step by step

How we produce the poles

We use the time-honoured Soviet production technology to manufacture the supports. The material is northern pine, which has a denser and less porous structure than species growing in the Russian midlands.

Главная
1.

Timber harvesting

Only straight logs of 6-13m length are used for the manufacture of supports, in quality corresponding to GOST 9463-88.
Главная
2.

Debarking and peeling

Debarking is done on the Morbak C-40 - the result is a perfectly smooth surface. Power of the machine is 100 hp and the debarking speed is up to 10m/min. The diameter of the debarked logs is 10-61 cm.
Главная
3.

Wood drying

We use both atmospheric drying and 3 drying chambers. The use of soft technology avoids cracking of the wood. For impregnation, we send timber blanks with a moisture content of no more than 28%.
4.

Impregnation with protective coatings

The water-soluble preservative of the CCA group "Elemsept" protects wood against rotting, insect damage, mould, etc. It does not leach out and is environmentally friendly. The surface of the pole stays clean and dry. There is no unpleasant odour, no special safety precautions during installation and maintenance. Impregnation of wooden pylons is carried out in autoclaves by vacuum/pressure/vacuum technology (GOST 20022.6-93). Under vacuum, excess moisture is extracted from the supports. Then, the antiseptic solution under pressure penetrates deeply into the wood. In the third step, the preservative is evenly distributed in the wood under vacuum conditions.

5.

Binding the antiseptic compound

The antiseptic is fixed in the wood in an autoclave using heated steam. The wood is then cured by means of an autoclave using heated steam.

Antiseptic

Advantage of the antiseptic used

With poles impregnated with CCA group antiseptic, no reinforced concrete footing is required for installation in the ground, unlike wooden poles impregnated with other types of antiseptic (XM-32, ACC-1)

GTC

Strict quality control at all stages of production

1. Checking incoming raw materials

The wood raw material is carefully inspected for rot and cracks.

2. Bend test

A 7-metre support must be able to withstand a load of at least 350H applied at 0.6m from the top (carried out prior to impregnation with antiseptic).

3. determination of the impregnation depth

Главная

The impregnation depth is checked with a core sampler. The minimum impregnation depth is at least 85% of the sapwood width. In practice, up to 100% of the sapwood is impregnated.

The impregnation process data (temperature, pressure) and the control data obtained shall be recorded as the factory certificate for the given batch of poles.
