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.
Why A.C.S.R conductors are prefer for transmission and distribution lines?
ACSR is often used because it is cost effective. aluminimum is cheaper than copper,and is a good conductor, it is lighter which allows structures to be built cheaper (less stress on them), and the steel core provides great strength. Win-win.
Overhead cables are made of almunium not of copper explain?
Much of the newer overhead cables is made of aluminum with steel reinforcing it for strenght purposes. Aluminimum is much cheap, and much lighter, thus it is cheaper to use vs. copper for high voltage transmission, and copper has a lower resistance which means more electricity can get through the wire/ cable, which means more electricity can get around the world quicker. most people should use copper becasue it has a lower resistance where aluminuim has a bit of a high resistance not to much but a bit so that is why you use copper not alominuim.
What does load cell used?
It used loads for it.
Why ujt used as an oscillator?
why ujt used as amplifier
What is the name of aluminimum when it is dug out of the ground?
Aluminimum
Which element is lightwent does not corrode and is used in construction and cookware?

Is aluminimum a solid at room temp?
Yes

What kinds of products are made from south America forest?
aluminimum
What metal is mostly used with copper coated wires?
Wires are made of copper and sometimes coated with silver for use at frequencies above 1 GHz. Wires used on overhead power lines are usually stranded aluminimum with inner strands of steel.
Sag produced in the conductor of a transmission line depends on?
-The tension of the cable (the tighter, the less sag, but this can cause other problems if too tight) -The temperature outside (the higher the temperature, the more it will sag) -The amount of current flowing through the cable (the more current, the hotter the conductor will get = more sag) -The type of cable (aluminimum will sag more than copper; ACSR will sag less than straight aluminimum).
Why A.C.S.R conductors are prefer for transmission and distribution lines?

How conductivity effects power?
Conductivty is an electrical property of conducting materials. Silver has the higest conductivity, then copper then aluminimum. Conductivity does not really change with electrical wiring so the power will not be directly affected.
How do you find the engine pan plug on a 1.9L 1995 Ford Escort Estate wagon?
Access the plug from behind the passenger side front wheel. Reach up toward the front of the vehicle and touch the bottom edge of the engine oil pan. Just run your hand back and forth on the rear-edge of the engine oil pan. You'll feel the 5/8" bolt. That's the great thing about the Escort... you can change the oil without having to get under it. It only has to be jacked-up just enough to fit an oil drain pan underneath it. The oil filter can be easily reached from the top. The drain pan is aluminimum and aluminimum is soft. BE SURE not to overtighten that drain plug!
What is the difference between Magnet wire and copper wire?
Copper wires are made of copper and aluminimum wires are made of aluminimum. Don't work aluminimum wiring unless you know exactly what you are doing. It will react with copper wire and wiring devices and will start a fire. There is special grease and wiring devices to prevent this that you need to use. If you have aluminimum wire, make sure you do your homework. ------- The electrical capacity of any type of cables/wires are depending on the heat withstand capacity of the material wich can be calculated with the product of square of current, Resistance of the material and Total time for flow of current. I2RT. Resistance again can be calculated as R=rho*L/A where rho is the resistivity, L is the length and A is the area of cross section. So for a fixed current flow and fixed Length of wire the area of cross section of the cable is directly propotional to the resistivity. resistivity of copper is 1.68x10 power -8 and that of Pure Aluminum is 2.82x10 power -8. So.. for a specific current flow, an aluminum cable size shall be 1.7 times that of copper cable. This also is not recommented as the Aluminum resistivity varries with the alloys and even with casting. 2.5 times the size of copper can be recommented for Aluminum cables. Also as the temporature expansion of Aluminum is 3 times that of copper. So all the termination and joining areas shall be treated more sensible that of copper. No need to be afraid to use Aluminum cable if you work with the proper recommented size.
How the electricity suppliers try to keep energy losses to a minimum?
The main way they do it is to try and reduce the resistance of wires as much as possible so that power is not lost in heat in the cables. To do this the main method is to use thicker wire, which has less resistance and lower losses. However copper and aluminimum for wires and cables cost money so the idea is to try and reach a balance between wire costs and the cost of wasted energy.
