Why dampers are used at the end of tower in transmission lines?
To 'damp' vibrations in the conductors.
What is the difference between bundled conductors and composite conductors?
Bundled conductors are used to reduce the effect of corona. As in place of a single conductor. two conductors are used in parallel the voltage gradient build up is less and thus the ionisation of the surrounding air is decreased. Therefore the effect of corona is reduced.
What is a pole transformer?
It is a type of transformer that you usually see hanging from a utility pole that feeds your house. It transforms the high transmission voltage down to the usable voltage that is used in the home.
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.
Why neutral for High voltage?
High voltage transmission and distribution lines utilise three-phase electricity. There are two commonly-used connections used in this system, termed a 'delta' and a 'star' (or 'wye') connection. A delta connection provides three energised conductors, termed 'line conductors', while a star connection provides three energised conductors ('line conductors') together with a neutral conductor. However, in the case of a star connection, provided the load is balanced, no current flows through the neutral conductor. In the case of high-voltage transmission and distribution lines, their loads are very close to being balanced, so there is no need to provide a neutral in the case of a star-connected system, as any slight imbalance can be compensated for in slightly different line currents.
What types of conductors are used in energy transmission?
Alluminium wire
Why dampers are used at the end of tower in transmission lines?
To 'damp' vibrations in the conductors.
What does a 3 pole circuit breaker do?
It provides power to 3 conductors simultaneously, and more importantly, disconnects all three conductors simultaneously in case of a fault. A three pole breaker is used with a three phase power system.
What are the components used for trnsmission lines?
There are no component is used in transmission line . the used things are- conductors for transmitting power to one place to another place. insulator for separate these conductors and some other basic things are required necessary for net of transmission line.
What is pg clamps in transmission line?
pg clamp is known for parallel groove clamp,especially used in transmission line to hold transmission conductors in parallel.
Hollow conductors in transmission line used to?
To reduce skin effect.CommentHollow conductors are not used on electricity transmission lines. Transmission-line conductors are normally manufactured of stranded aluminium conductors, wound around a steel-wire core. The steel core improves the conductor's tensile strength.Hollow conductors are, though, used as 'wave guides' in radio-frequency circuits. However, their purpose is not to reduce skin effect (in which most of the current flows close to the surface of the conductor), but to save copper -if most of the current flows close to the surface, then there's little point in using solid copper!AnswerHollow conductors are used on very high voltage underground cables, which are cooled by passing oil or gas through the conductors.
What are the different types of conductors used in transmission?
Overhead transmission lines use steel-cored stranded aluminium conductors. The steel supplies the necessary tensile strength, as aluminium is relatively weak. Copper is not generally used as it is significantly more expensive than aluminium.
What fluid is used in the rear differential of a suzuki king quad 700?
Mobil 424 hydraulic transmission tractor oil or Amsoil tractor hydraulic transmission oil

Why do copper or aluminum wires generally used for electrical transmission and distribution purposes?
Both metals have a low resistance to conductivity. They are extremely flexible and do not degrade under electrical transmission as do other metals. They are less expensive than the best conductors, silver and gold.
What are the advantage of stranded conductor over solid conductors in a transmission line?
In a transmission line, voltage is stepped up to a very high value. This is so as to take advantage of lower line current and smaller conductor size. At these potentials1, however, like charges repel, so most of the current flow is along the skin of the conductor. Stranded conductors, even wound wire over insulating rope, is more efficient, and more cost effective, than solid conductors.--------------------------------------------------------------------------------------------------1 Actually, this effect occurs at any voltage, but it is most notable at the very high voltages used in power line transmission systems.AnswerStranded conductors are used because of their flexibility compared with solid conductors. Normally, transmission lines consist of a steel-wire core (which provides strength) around which are wound stranded aluminium conductors.
