Basic principles and concepts of power transmission

Voltage: Voltage is used as a measure of electrical pressure in an electrical system and is measured in volts (V).
Current: Current is used as a measure of the number of moving electrons in an electrical system. And it is measured with the unit of an ampere (A)
Power: Power is used as the amount of work done by an electrical system per unit time and is measured in watts (W).
Energy: Energy is used as the amount of work done by an electrical system in a period and is measured in units of Joules (J).

Types of power transmission bases and telescopic beams

Regarding the types of power transmission bases, we can categorize them as follows:

AC power transmission bases: AC power transmission bases include transformers, lines, and switches that are used to transmit electricity with AC voltage. These types of foundations are used in high-voltage electrical systems such as power plants and power generators.
DC power transmission bases: DC power transmission bases include lines, switches, and electronic equipment that are used to transmit electricity with DC voltage. These types of bases are used in low-voltage electrical systems.
Aerial power transmission bases: Aerial power transmission bases include power lines and poles that are used for high-voltage power transmission. These types of foundations are used in remote and mountainous areas due to the difficulty of accessing the land.
Underground power transmission bases: Underground power transmission bases include lines, cables, and electronic equipment that are used for low-voltage power transmission. These types of foundations are used in urban areas due to the lack of impact on the environment and improving the appearance of the city.
Linear power transmission bases: Linear power transmission bases include lines, switches, and transformers that are used to transmit high-voltage electricity linearly. These types of bases are used in open and remote areas due to ease of installation and no need to build electric poles.
Submarine power transmission bases: Submarine power transmission bases include lines, cables, and electronic equipment that are used for low-voltage power transmission under the sea. These types of foundations are used in marine areas due to the lack of impact on the environment and improving the appearance of beaches.

Telescopic beams

These beams are made of metal and different lengths and are used as part of power transmission lines. In addition to power transmission, telescopic beams have other tasks that will be discussed further.

Power transmission: Power transmission from the starting point to the destination point is one of the most important tasks of telescopic beams. Using their physical properties, such as electric current and magnetic field, these beams transmit electricity from the starting point to the destination point.
Support for power transmission lines: these beams act as physical support for the lines and by bearing the pressure and weight of the lines, they keep them in the correct path and prevent them from breaking and being damaged.
Resistance to weather conditions: Telescopic poles must be resistant to various weather conditions, such as wind, rain, snow, and dust. These beams provide the necessary resistance against weather conditions by using their metal material.
Safety against accidents: Telescopic booms should be safe against various accidents, such as earthquakes, floods, and fires. These beams, using their metal material, provide the necessary resistance against accidents and prevent the dangers caused by them.
Reducing voltage drop: Voltage drop in power transmission lines is one of the basic problems that can be reduced by using telescopic beams. By using telescopic poles with appropriate lengths, the amount of voltage drop in power transmission lines is reduced.
Improving the quality of electricity transmission: using telescopic poles with the right length improves the quality of electricity transmission. By reducing the voltage drop and increasing the stability of power transmission lines, the quality of power transmission improves.

In general, telescopic beams are one of the main structural components of the power transmission system, which, in addition to power transmission, can help improve the quality of power transmission and reduce costs related to the maintenance of power transmission lines.

Metal cutting and bending: By using metal bending and cutting machines, various parts of the rig are prepared. Metal parts include metal mesh with different diameters, side parts, and metal bases.
Parts welding: the parts prepared in the previous step are connected using a welding machine. At this stage, welds must be done carefully on the metal parts to make the mesh metal mast with the required strength and stability.
Metal bases: Metal bases are a part of the mesh metal mast that are used to install and fix the mast on the ground. These bases are connected to the mesh metal mast using nuts and bolts.
Painting: The mesh metal mast is painted to be resistant to various weather conditions, such as rain and corrosion.
Installation and registration: In this step, the mesh metal mast is installed and fixed. The metal legs of the mast are fixed to the ground using nuts and bolts, and the mesh metal mast is installed on them.

Introduction to Materials and Manufacturing Process of Lattice Steel Towers

The previous section described the manufacturing steps of lattice steel towers. To enrich this section, more details can be provided on the raw materials and the manufacturing process:

Raw Materials:

Steel Sheets: Steel sheets with different thicknesses are used depending on the size and load-bearing capacity of the tower. Galvanized steel sheets are used to prevent rust.
Accessories: In addition to steel sheets, accessories such as high-strength galvanized bolts and nuts, industrial anti-rust paints, and other connecting parts are used to build the tower.

Manufacturing Process:

Design and Engineering: In this stage, engineering drawings and calculations related to the dimensions and thickness of the sheets, the number and arrangement of the lattice members, and the connections are performed based on the tower’s application, voltage, and load-bearing capacity.
CNC Cutting and Punching: Using CNC cutting machines, the different parts of the tower are cut with high precision, and the necessary holes for connection are created on the steel sheets.
CNC Bending: Some parts of the tower need to be bent for proper shaping. This process is also carried out with high precision using CNC bending machines.
Welding: The connection of the cut and bent parts is done using appropriate welding methods such as Shielded Metal Arc Welding (SMAW). In this stage, the quality of the welds is of high importance to ensure the strength and safety of the entire tower structure.
Hot-Dip Galvanizing: To prevent corrosion, the manufactured towers are immersed in baths of molten zinc. This process creates a zinc coating on the steel surface that increases its resistance to weather factors.
Final Inspection: After completing the manufacturing steps, quality control is performed to ensure that the towers meet the required standards and specifications.

In addition to the details provided for AC transmission towers, the following can be mentioned for other types of towers:

DC Transmission Towers:

Advantages:
- Higher efficiency over long distances: DC current has lower losses than AC over long distances and is more suitable for transmission over very long distances (hundreds or thousands of kilometers).
- Reduced losses in underground lines: DC current has lower losses in underground cables than AC.
- Enabling smart grids: DC technology allows for better management and control of electricity flow in smart grids.

Overhead Transmission Towers:

Application: These towers are used to transmit electricity in remote, mountainous, and sparsely populated areas where access to land for cabling is difficult.
