In this blog, we have covered everything like types of towers, their key parts, design aspects, and how to find transmission line tower manufacturers in India. So, let’s get started without any further delay!
What is a Transmission Tower? A transmission tower, also known as an electrical tower, is a tall structure that supports power lines and transmits high-voltage electricity across long distances. These electrical towers are essential in maintaining a stable electrical system by making sure that the electrical power reaches every corner of the country. The primary purpose of Transmission line tower manufacturers is to provide the necessary height and support for power lines so that they can carry electricity without interference from obstacles like buildings or trees.
What is a Transmission Tower? If we did not have these electrical towers, it would have been impossible for us to transmit electricity over long distances and build the modern infrastructure that we have today! And there are many minute details and detailed designing is done to build a transmission tower with multiple parts. Let’s have a look at what these parts are in the next section.
What Are the Key Parts of a Transmission Tower? • There are many parts that engineers put together to design an electrical tower. This complex structure of the tower ensures the stability & safety of the entire ecosystem. We have mentioned all the key parts of a transmission tower for your reference below • Peak: The peak is the topmost part of the tower. Generally, insulators are placed at a peak. The role of these insulators is to prevent the transmission lines from coming into contact with the metal tower. • Cross Arm: The next important part of the electrical tower is the cross arms. In simple words, the cross arm is the horizontal lines (structure) that extend from the tower to provide support for the power lines.
What Are the Key Parts of a Transmission Tower? • Boom: Moving next, a boom in the transmission tower is a vertical or angled structure that holds the cross arms which helps in supporting the weight of the lines. • Cage: Cage is another key component in electrical towers. They act as a protective structure around the tower that prevents accidental contact with the power lines while ensuring the safety of maintenance crews. • Transmission Tower Body: As the name suggests, transmission tower body is the main frame of the tower. It is made of steel and covers the highest coverage of the tower.
What Are the Key Parts of a Transmission Tower? • Legs: Legs in the transmission tower are the vertical support elements that provide the necessary stability for the entire tower. • Stub/Anchor Bolt and Baseplate Assembly: If there’s something that secures the foundation of the tower in the ground, then it’s a stub. By bonding the tower with the ground, anchor bolt and baseplate assembly make sure that the tower remains steady under all conditions. • Foundation: Last but not least, the underground structure of the tower is known as the foundation. It provides long-term support and anchors the entire tower to the earth.
What Are the Key Parts of a Transmission Tower? Each of these components of an electrical tower plays an important and specific role in making sure that everything functions correctly and performs at its best efficiency. Moreover, the parts of an electrical tower can differ a little based on different types of towers. Yes, there are multiple types of towers that make it possible for electricity to reach every city and corner of the country. If you are unaware of these types of towers, let’s learn more about them in the following section.
What Are the Different Types of Transmission Towers? Transmission towers come in various types, each designed for specific needs and conditions. Let’s take a look at the most common ones: 1. Suspension Towers: Suspension towers are used in straight paths for power transmission, and they are the most common type of tower. The suspension tower is also called an anchor tower or tangent tower.
2. Tension Towers: Moving next, another type of electrical tower is a tension tower. They are designed to handle the increased tension of power lines, especially when they change direction. So, they are used where the transmission line has some angle. The tension tower is also called a deviation tower. 3. Terminal Towers: Located at the ends of transmission lines, these types of towers help connect power lines to the rest of the electrical grid.
4. Transposition Towers: Transposition towers make sure that there’s a balanced flow of electricity by changing the physical configuration of the transmission line conductors in a polyphase system and reducing the voltage imbalance in transmission line conductors. 5. Self-Supporting Towers: As the name suggests, these types of towers don’t require external support and are ideal for rough or uneven terrain. There are mainly four types of self-supporting towers - 1. Narrow Base Towers, 2. Broad Base Towers, 3. Tangent Towers, 4, Deviation Towers. Each of these types is used for different kinds of geographical locations.
6. Guyed or Stayed Towers: There are two types of guyed towers – portal structure type guyed towers and V structure type guyed towers. Supported by guy wires, these towers offer additional stability, especially in challenging environmental conditions. 7. A Type, B Type, C Type, and D Type Towers: • These variations of transmission towers are designed for different load capacities and environmental conditions. Here’s a quick overview of each of these types – • A Type Tower: These are suspension towers with a 0-2° angle deviation, having two legs and suspension-type insulators. They are used when there are minimal direction changes.
7. A Type, B Type, C Type, and D Type Towers: • B Type Tower: These are tension towers with a 2-15° angle deviation, equipped with two legs and tension-type insulators. They are suitable for moderate direction changes. • C Type Tower: C Type towers are tension towers that are designed for 15-30° angle deviations with three legs. They are ideal when there are significant direction changes. • D Type Tower: These types of towers are built for 30-60° angle deviations to make sure there’s enough stability in sharp line direction changes.
8. Single Circuit Towers: As the name suggests, single circuit towers are used for carrying a single circuit of electricity and they have only one line's conductors on the one tower. 9. Double Circuit Towers: Double circuit towers carry two circuits on a single tower which helps them reduce the number of towers required to distribute the electricity. 10. Multi-Circuit Towers: When there are more than two circuits on the tower, it optimizes the space and reduces the cost of electricity distribution.
11. River Crossing Towers: As you would have guessed by the name, river crossing towers are the ones that are specially designed to cross water bodies. These towers are taller and have zero-degree angle deviation. Plus, modern-day river crossing transmission towers have a span of 800m. 12. Railway Crossing Towers: These towers are designed to safely cross railway tracks while maintaining the stability of power lines. One more interesting thing you need to know about the railway crossing tower is that the minimum distance of the crossing tower from the center of the railway track is equal to the height of the tower plus 6m. Plus, the minimum distance of the conductor from the surface of the railway track is equal to 17.90m. The railway crossing span is limited to 200m.
13. Road Crossing Towers: Similar to railway crossing towers, these types of towers are designed for roadways. Road crossing towers have double tension hardware with double insulators for the purpose of protection. Additionally, the minimum distance of the lower conductor of the road transmission line to the road surface is equal to 12m. The span length for road cross towers is not more than 250m. 14. Lattice Towers: Talking about lattice towers, they are made of multiple interconnected steel structures that form a grid-like design. Because of this design, lattice towers can withstand external forces such as high winds and heavy loads.
14. Lattice Towers: Due to strong resilience power, Lattice towers are well-suited for long-distance power transmission, where the towers need to support heavy cables and withstand environmental stressors. Moreover, the open design of the lattice framework also makes these towers less susceptible to corrosion, especially when treated with appropriate coatings, which enhances their durability. The height of Lattice towers can vary with some reaching over 100 meters. Plus, the space of these towers can cover several kilometers depending on their usage. The efficiency and strength of lattice towers make them a popular choice in both urban and remote locations, balancing cost-effectiveness and structural integrity.
15. Tubular Towers: Moving next, tubular towers are made from solid steel tubes which makes electrical towers more compact and resistant to wind. 16. Monopole Towers: As the name suggests, monopole towers, also known as single-pole towers, are typically used in urban areas where space is limited. Made from materials like steel, concrete, or composites, these towers typically are between 30 to 100 meters with a slim, tapered design that minimizes their ground footprint.
16. Monopole Towers: One of the main advantages of monopole towers is their space efficiency. They occupy less land compared to traditional lattice towers and are visually less intrusive. They also tend to have lower wind resistance due to their solid structure, making them more stable in extreme weather conditions. However, their construction can be more expensive, and they are not always suitable for carrying heavy loads, which can limit their use for high-capacity power transmission or large antenna arrays. Moreover, maintenance of monopole towers can be more difficult, particularly for very tall towers, as accessing the upper sections requires specialized equipment. So, in short, while they are ideal for telecommunications and electrical distribution in urban areas, they may not be as cost-effective or structurally suited for some rural or high-capacity applications.
17. Hybrid Towers: Lastly, hybrid towers combine multiple design features to optimize functionality, making them versatile and suitable for various environments. Each type of transmission tower serves a specific purpose, allowing transmission lines to maintain reliability across different terrains and conditions. Now that you know the types of transmission towers, you must be wondering how these transmission towers are designed, right? Let’s find out about the art of designing transmission towers.
How is a Transmission Tower Designed? When an electrical engineer starts to design a transmission power, it takes a lot of time, energy, and effort. He/she needs to consider various factors such as the material to be used (typically steel or concrete), the height of the tower, the weight it must support, and environmental conditions (wind, temperature, and seismic activity) to make sure that the tower remains stable and durable for a longer period of time. Moreover, Practices of transmission line tower manufacturers also need to take care of safety regulations like the security of maintenance workers and the general public. But what happens when the design phase is done? It’s time to utilize these electrical towers for power distribution. Let’s understand how that happens in the following section.
