Installation and commissioning of the new line at the Client’s site is carried out by our qualified team.
Prestressed concrete poles E type, produced by the LSW 2 – 54 line, are an excellent replacement for wooden and reinforced concrete energy poles. They are the future and their application is progress and modernity. They are product for the 21st century.
Comparing to wooden and reinforced concrete poles, they are characterized:
- Period of use min. 30 years with preservation of surface quality min. 10 years. The life expectancy of poles is up to 100 years
- Transferring much greater forces than wooden or reinforced concrete poles
- No need to use guy ropes so there are various possibilities of pole-top constructions
- Much greater resistance to environmental conditions, e.g. strong winds
- A diverse assortment of dimensions and strength classes
- Very low maintenance costs
Our prestressed concrete poles transfer much greater forces than wooden or reinforced concrete poles, and thus are much more resistant to environmental conditions, e.g. strong winds.
This is due to the tensioning force, which is transmitted through the reinforcement basket inside the pole or more precisely through the prestressing reinforcement. This reinforcement is a set of prestressed steel wires according to ASTM A421, to which appropriate force was applied during the production process. The magnitude of this force together with the arrangement and the amount of prestressing wires and additional reinforcement is responsible for the value of the apical force transferred during the whole period of operation by the poles. The poles manufactured by our line comply with the CSA-A14-07 standard.
This is confirmed by strength tests according to CSA A23.1-14 / A23.2-2014
This test is carried out by applying a nominal force to the top of the pole and tempering. Another application of the force until the first scratch appears on the concrete surface.
Then increasing the bending moment leads to the destruction of the pole and confirmation of the expected value of the apical force, which can be safely transferred through the pole during the entire service life..
Thanks to the above, our poles have a much greater resistance to environmental conditions, e.g. strong winds than wooden or reinforced concrete poles.
What is extremely important in a socially crisis situation, our poles do not require any maintenance. It is not required to refresh or protect their surfaces with any substances or paints every year.
In connection with resistance to hurricane winds, they are practically maintenance-free element of the power network, because it is much faster to restore power line cables damaged by forces of nature than to additionally restore new poles.
The excellent surface quality of our poles results from the use of non-collapsible instead of split molds, which additionally ensures shorter production time, attractive appearance and longer surface durability.
On the surface of our poles there is no seam resulting from the longitudinal split of the mold, so there is no place where calcium is leached from cement.
Depending on the client’s requirements, the reinforcement basket can be designed for the expected value of the apical force, thanks to which you can get a great variety of the assortment of dimensions and strength classes of poles for various applications. Moreover there is no need to use guy ropes.

Our non-collapsible molds therefore increase the efficiency of the entire line.
The service of non-collapsible molds on the line takes place at their ends. There is no opening and closing of the molds so the production process can be much faster.
The process of filling our non-collapsible molds with a concrete mixture is very fast and involves entering the filling nozzle inside the mold.
Split molds must be unscrewed and filled from above and then screwed again. It takes time and affects the cost and efficiency of production.
Quick entry of the filling nozzle into our non-collapsible mold
Filling the split mold from above
Dismantling poles from our non-collapsible molds is very easy and fast – by pushing out, while for split molds the whole mold must be unscrewed.
It takes much longer, affects costs, production efficiency and product quality.
Fast pushing out of the finished pole from our non-collapsible mold
Two steps necessary to dismantle the split mold and take out the pole
Putting into our non-collapsible molds, reinforcement baskets and reinforcement tension takes place very quickly.
Another advantage of our non-collapsible molds over split molds is the lack of a connection line around the perimeter.
No connection line on our molds
Connection line on the split mold on a rolling rings
Due to the lack of connection lines around the perimeter of our mold, the spinning process is smooth and silent.
Spin speeds can therefore be faster and the whole process shorter.

So what does the process of designing and realisation line looks like for a specific Client?
The LSW family line is actually a chain of interconnected device groups. It is a great mechanism that, when properly powered and operated, produces the final product – prestressed concrete spun poles.
The first step is to prepare a personalized offer for a specific customer.
Then we prepare the layout of the line in the constructed or existing hall.
Groups of devices that make up the LSW industrial line.
LSW 2 – 54 industrial line consists of 7 groups of machines, so these are:
- Filling group

Description of the process of implementing the offer for the Client.
When the production of equipment in Poland begins, we are in constant contact with the Client subcontractor for the construction.
We verify with the subcontractor the location of connection points for powering machines and the correctness of execution of the foundations under spinners.
All machines from the line are successively sent by sea or land to the Client. Thanks to this, it is possible to start smoothly assembly process and first trainings on handling line devices at the Customer’s, even before the end of production of all equipment.
This results in a smoother investment implementation and Client safety from the risk analysis point of view.
Installation and commissioning of the new line at the Client’s site is carried out by our qualified team.
Client employees trainings for line service are performed in English.
Full technical documentation of the line equipment (in English) is provided during commissioning.
We supervise the operation of machines in line and support the Client during start of the production.
The Client’s training package also includes 2 free service visits. During these visits, the correct operation of all the machines is checked.
All necessary adjustments are made under the warranty.
