What are the types of dampers used in buildings?
Liquid filled dampers Air filled dampers Mechanical dampers Rubber pad dampers Spiral dampers
What are seismic dampers and why are they important?
Seismic dampers are devices used in building construction to protect the buildings against earthquake and other seismic events.
What is length of the towers that is used on transmission lines?
That is depends on the factor of sag and clearance required. And also on the level of voltage transmission used.
HVDC transmission lines being used in Pakistan?
it will be implemented soon...planning is in progress
How many wire are used in transmission line?
Transmission lines are three-phase systems. There are three line conductors in a three-phase system. However, to reduce electric stress at higher voltages, these lines are frequently made up of 'bundled' conductors -so each line might have two, three, or four separate conductors. In addition, transmission towers usually carry separate circuits -i.e. separate three-phase circuits on opposite sides of each tower. So, in the UK for example, a typical 400-kV transmission line will consist of two, separate, three-phase circuits suspended on each side of each tower, with each line consisting of four bundled conductors. That's 24 conductors.

What is the major material used in constructing transmission lines?
The major material used in the construction of transmission lines is aluminum alloy. Steel is also used to reinforce the lines. No insulation is used for overhead transmission lines.
Why use transposition tower in long transmission tower?
Transmission towers are usually made of steel to help support over the head power lines. They are used in high voltage AC and DC systems and can come in different shapes and sizes.
Distance between transmission tower and telecommunication tower?
Transmission towers are usually paired or grouped and used to convey high-tension power lines over distances. Do not confuse with antennas used for radio or TV transmissions. a telecommunications tower is used for broadcast purposes -radio or tv or both. neither type of tower is necessarily manned- power- transmission towers are normally unattended and high up. There you have it. good to see an interest in civil engineering structures- things are looking up!
What are the relay used in transmission line?
mho rerlay is used in long transmission lines
What is the purpose of ground wires in overhead transmission lines?
connection of the ground of all the transmission lines and used as a communication cable between protection devices

What is length of the towers that is used on transmission lines?
That is depends on the factor of sag and clearance required. And also on the level of voltage transmission used.
Where is Television transmission tower in los angeles?
They used to be on Mt. Baldy - above Pasadena.
What types of wire are used in transmission lines?
Stranded aluminium, with a steel core.
Why transmission lines are thicker than TV cable wires?
Transmission lines are thicker than TV cable wires because the transmission lines are used to transmit both low freq and high freq signals. And the losses of the transmission lines depend the resistance of the line which inturn depend upon length and area. As we have to transmitt the signals over long distances the transmission lines are thicker in size.Whereas in TV cable wires the construction is totally different in which transmission of signals is in between two conductors thereby avoiding losses.Therefore there is no necessity for these lines to be made thicker. That is why transmission lines are thicker than TV cable wires.
Why copper is used in electrical transmission line?
Copper is a good conductor and is fairly strong. It generally is not used in power transmission lines due to cost - generally aluminimum is used.
