Power Transmission Lines and Towers Market Overview

“The Global Power Transmission Lines and Towers Market is expected to grow rapidly at a 7.2% CAGR consequently, it will grow from its existing size of from $28 billion in 2023 to $52.85 billion by 2030.”

What Is a Transmission Tower?

Transmission towers support overhead power lines. Transmission towers can also be called power transmission towers or electricity pylons. Transmission towers are used to carry high-voltage lines to transport electricity from generating stations to electrical substations. Electrical substations deliver power to end users via distribution lines. Utility poles are used to carry low-voltage conductors on the distribution line.

Transmission towers must be able to safely support the transmission conductors, which are heavy. All towers must also be able to withstand all types of natural disasters. The transmission tower is a complex engineering task that requires civil, mechanical and electrical engineering principles to be applied.

Transmission towers: 4 different types and their applications

Every high voltage transmission line is supported by a transmission tower. Transmission towers (also called power towers, transmission towers, or electricity poles) are tall structures (usually made of steel lattice) that support high-voltage conductors on overhead power lines. Transmission towers are different from traditional power poles because they carry bulk electricity over long distances from multiple high-voltage lines, as opposed to a single pole that provides local delivery.

Transmission towers are available in different types.

The following list is an overview of the different types of transmission towers, based on their technical background.

Take a closer look at them all one by one.

Suspension Towers

The high voltage suspension towers can only support the weight of a conductor when it is positioned in an upright position. The conductors of suspension towers are held in place either by V or I strings. Transmission towers suspended from the ceiling run in straight lines when there is a maximum of a 5 degree angle deviation.

Transposition Towers

These towers are commonly used in three-phase systems to support and maintain transmission lines. The weight of the line in the middle puts great stress on the structure. The body, cage and peak of a transposition tower are all supported. The conductors and the lines are placed at a distance to prevent contact between the tower cross arms.

Tension/Angle Towers

The towers are designed to support the change in direction of transmission lines at turning points with an angle greater than 5 degrees. Anchors are used to reinforce the tower in order to resist pressure against the angle. A section is the transmission line connecting two angle towers. The length of a section is determined by the location, easements and possible placement options, as well as the final destination.

Special Towers

When environmental conditions require a large amount of support or a change in the angle, custom towers can be built. Transmission towers are affected by a variety of factors, including heavy winds, porous soils, freezing rain and more. These towers can also be used for areas such as long-span rivers crossings, valley crossings, power lines crossings above or below existing lines.

Power transmission lines are electricity-transferring systems used for the transmission of electrical energy from generating substations to various distribution stations. These lines consist of four main components: resistance, capacitance inductance and shunt conductance.

Interconnected lines allow electricity to be moved from the generator site to the distribution point. Transmission towers can also be used for high-voltage AC or DC applications, to carry heavy and safety-critical conductors.

Transmission towers must be able to support the heavy conductors at a height that is both safe and cost-effective. Transmission towers must therefore be designed to withstand normal calamities. These towers are primarily used by distribution companies to generate, distribute, and transmit generated power.

The transmission towers are made of high-tensile steel and designed according to the supply frequency and control rating for the conductor. This allows them to withstand normal temperatures and calamities without any losses. After calculating the SAG, transmission towers that carry high-tension conductors and have ground-level clearance should be designed appropriately.

Demand Outlook

The industry will be positively impacted by the growing demand for electricity and the favorable standards of the government in relation to the development of smart networks. A critical increase in speculations towards cross-border networks in accordance with the growing integration of renewable energy across the globe, will also positively impact business outlook.

Transmission & Distribution industry growth will be boosted by a worldview shift towards the development of current network infrastructure, as well as positive client attitudes regarding the integration of artificial insight systems. The application of IT to the control industry is also expected to create smart networks that will in turn complement the need for efficient transmission systems.

The business outlook is also driven by increasing investment in transmission lines infrastructure. The 221 kV - 660 kV power transmission line & towers segment will see a boost due to the deployment of high voltage electric networks in developing countries, coupled with the rapid urbanization. In December 2019 GE secured a project for a 1215 MW wind farm in China that will provide electricity to 850,000 homes. The industry will also benefit from the refurbishment and upgrading of T&D network across developed nations.

To meet the growing energy demand in the commercial and mechanical divisions, the development of ultra-high and extra-high tension transmission foundations will complement HVDC control line trade development.

Grid Solutions, a division of GE Renewable Energy, along with EDF Renewables & ESB, won an order in 2020 to supply 450 MW of low-carbon energy on Scottish electricity grids by 2023. The key factors driving product penetration are low short-circuiting current, marginal line losses, and greater controllability.

The electricity transmission towers industry may be affected by factors like varying steel prices and availability, as well as import and export restrictions. Over the forecast period, it is expected to slow down the growth of the market globally. The market is also expected to benefit from the increasing demand for transmission towers.

Growing interest in adopting a renewable energy mix and increased demand for efficient lines and towers with low energy losses drive market growth.

The market is expected to grow due to the increasing power consumption, and the favorable government policies that encourage the construction of smart grids. An increase in investment in grid networks across borders. Global integration of renewable energy networks may be beneficial to the market.

Market growth is likely to be boosted by a paradigm shift towards expanding the existing grid infrastructure, and positive consumer attitudes towards integrating artificial intelligence technology. IT applications for the power industry will also likely contribute to the advancement of smart grids. This is expected to increase the demand for transmission systems.

Power transmission lines are systems that transport electricity from a substation, to multiple distribution stations. These lines are primarily composed of inductance components, resistance components, shunt conductance components, and capacitance. These are interconnected cables that allow for proper movement of electricity from the generator site to the distribution point.

Business growth will be driven by the rising trend towards the adoption of renewable energy mixes, coupled with a growing demand for lines and towers that are efficient with minimal energy loss. The industry will also benefit from increasing investments in the refurbishment and retrofitting existing transmission & delivery infrastructure, as well as increased installations of power infrastructure throughout developing nations.
