Which conductor do you use in overhead lines installation?
Kapilnamandixit
There are lots of choices for type of conductor - ACSR is a very common one. In my experience aluminum is the most often used metal. ACSR uses aluminum to carry the current, and also has a steel core that provides added strength.

Can I get example of Insulated overhead power lines more than 50kV with Images?
Voltages in that range do not use insulation around the conductor. They are bare conductors and use air and separation from one another for the insulation factor.
What is the voltage of British rail overhead lines?
On the main railway network, overhead lines use 25kV AC. In the past, some lines used 1500V dc overhead and 6.25kV ac overhead as well, but these have all been closed or converted. Tram and light rail systems use other systems.
To use your left hand to derermine the direction of the voltage developed in a moving conductor in a stationary magnetic field ou must point your?
The answer choices weren't provided. To use your left hand to determine the direction of the voltage developed in a moving conductor in a stationary magnetic field you must point your forefinger in the direction of the lines of force.
What is the cu cable size in 400a load?
A 0.15Cu cable has a rating of 382 amps summer and 476 amps winter. 0.2Cu allows 425/530 amps. That is for outdoor use in overhead lines.
Iec 60502 2xfgy 61kv xlpe can you use the armour as grounding conductor?
NO some armored cable has a ground some sealtite has copper in the helix wit the drain shield some liquite has no conduction at all all armor is a helix which is a coil and acts as insulation at hi frequency xlpe cross linked polyethylene is an insulator service cable is never used for grounding grounding electrode conductor grounding equipment conductor grounding conductor are all separate from service cables if a tall trucks hits an overhead cable you dont want to lose the ground in short NO
What type of metal is a great conductor of electricity?
Silver is the best conductor of electricity, with copper a close second. Gold is third on the list followed by aluminium. Power distribution systems commonly use copper for underground power lines and aluminium for overhead lines.

What situations use copper as a conductor?
Phone lines, power lines, and household cables.
How is copper used for electrical wire?
All the time. It's the best conductor of all the metals except silver which is too expensive to use and not much better than copper anyway. For overhead lines, aluminium is preferred because it is less dense and the towers to support the wires can be made more cheaply.
Why is metal use for electricity?
Metal is used because metals conduct electric current. The best conductor among the metals is silver, followed by copper, then aluminium. Copper is used for electrical wiring in the house and for underground supplies, while the lightness of aluminium makes it the metal of choice for overhead power lines.
What has the most common element used in wires?
Copper is used in electric wires because it is the best conductor of electricity that is known, apart from silver which is slightly better. For overhead wires a common material to use is aluminum because it is much lighter, although not such a good conductor. Overhead high-voltage wires usually use aluminium stranded wire with one or more steel strands in the centre to give strength.

Why are copper wires preferably used in electrical installation?
copper next good conductor to silver . it is cheaper .malleable ductile mechanically strong abundantly available so we use
Is a glass jar a good conductor of electricity?
Not at all. Glass doesn't conduct electricity. in fact they use glass as an insulator on electric lines.
Why we are not using iron as a electric conductor?
Sometimes we are (high tension lines) - but it weighs too much and has too high a resistance for "normal" use.
Why is 23.5 degrees used for two of the latitude lines geographers use?
Because those lines mark the places farthest north and south where the sun can ever appear directly overhead at any time of the year. The overhead sun reaches those places on June 21 and December 21 every year. It always stays between those two lines, and never crosses either one.
Why do Geograhper's use 23.5 degrees for two of latitude lines?
Because those lines mark the places farthest north and south where the sun can ever appear directly overhead at any time of the year. The overhead sun reaches those places on June 21 and December 21 every year. It always stays between those two lines, and never crosses either one.
