The intricate network of transmission power lines work their magic to get electrical current flowing from the source to the end-users. But no matter how resilient these lines are, there are many factors that can impact their performance and lead to their damage.
The result being interruption in electricity which diminishes power grid systems efficiency. This is why using the best fittings for transmission power lines is important in setting up durable and reliable infrastructure.
In this blog, we focus on two essential components – spacer and spacer damper. These fittings have a much important role to play in ensuring reliability and integrity of the power lines. Let’s explore what they are and what they can do.
What are Spacers?
It is essential to maintain a safe distance in-between conductors in transmission power lines. A spacer is a device that is precisely designed to keep that distance.
They are available in the market in different shapes and sizes, however, every spacer is designed to serve the primary purpose of preventing conductors from getting too close as this could result in short circuits or electrical arcing.
Role of Spacers
Here are some of the things that spacers can do in power transmission lines.
Preventing Galloping: Have you noticed how power lines sway uncontrollably during storms? If you’ve spotted such a thing then that is what is known as galloping. Galloping is not good for these lines as it puts stress not only on them but also on their supporting structures. Spacers are the solution to tame galloping as they control this movement by keeping the conductors separated at a safe distance.
Maintain Safety: Electrical faults are a common mishap to occur when conductors are too close to each other. With spacers in place, a safe environment can be maintained to keep maintenance crew and the public protected.
Improving Performance: Spacers reduce the likelihood of conductors lines coming in contact and their interference. This also contributes to secure overall efficiency and ensures high-performance in the power transmission system.
Now, let’s turn our attention to another component - Space Dampers.
What are Space Dampers?
Space dampers are specialised devices that are installed along the spacers’ length. They have a dual role of maintaining conductor spacing as well as dampening vibrations due to wind or other external factors.
Role of Space Dampers
Controls Vibrations: Power lines tend to vibrate upon their exposure to wind or other external forces. These vibrations when left unchecked leads to fatigue and worse conductor failures. Space dampers efficiently absorb the vibrations bringing down stress and extending power line lifespan.
Environmental Adaptability: There are many environmental conditions that impact the power line behaviour. These conditions can be temperature fluctuations, wind speeds, etc. Space dampers deflect the effects of diverse conditions and ensure consistent performance year-round.
At the Dutco Tennant LLC showcase for MEE 2024 exhibition, their partner PLP are coming with a wide range of spacer and spacer damper products. This is your chance to not only witness the best of these innovations but also gain in-depth knowledge about them.
Visit them in Hall 5, Booth D10 from 16-18 April 2024, at Dubai World Trade Centre to catch them live in action.
