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.

Why is aluminum used for cables instead of copper?
Al is lighter than Cu.
What is the cable size that are used in 11kv system?
It depends on the power rating of the circuit but a common size would be 95 sq. mm up to about twice that. 11 kV systems are usually 3-phase 3-wire. Underground cables use copper while overhead ones tend to use uninsulated aluminium or aluminium conductor steel reinforced (ACSR) cables.
What size wire do you need to run overhead to a 50 amp service five hundred feet away?
For that distance I would run AWG # 3 copper and install a sub-panel.
Composition of copper wire in generators?
how much copper is in copper wire
What is the current carrying capacity of sq mm copper and aluminium wire table?
For 3-core twin and earth cables up to 4 sq mm with reasonable air circulation, allow 8 amps per sq mm for copper and 5 amps per sq mm for aluminium. For permanent installations with high usage per day, use 4 amps per sq mm.
Why is copper good for making better pipes and overhead cables?
It conducts heat and electricity very well. It is good in pipes for keeping the heat in the water.
Why is lead used in high voltage cables?
Steel-reinforced aluminium cables are used for overhead lines because aluminium is much lighter than a copper conductor, despite not being quite as good a conductor as copper. The function of the steel reinforcement is to improve the tensile strength of the conductor.
Can Aluminum mylar-tape-shielded cables be used instead of Copper braid-shielded cables for instrumentation cables?
Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.
What is use as conductors?
Mainly metals. Silver is the best but copper is nearly as good and a lot cheaper. Aluminium is about 40% worse but is popular for overhead cables because they are lighter.
What is the element that is used for eletrical cables?
copper
What kind of wire is in PC ribbon cables?
Computer cables are often made of copper.
Booster cables - what is the difference in use between copper cald aluminum and 100 copper wire?
It depends on some factors which are not mentioned in the question. The main difference between 100% copper wire and copper clad aluminum is that IF they are the same diameter, then the copper will carry and stand up to more electrical current than the aluminum. If the diameter of the aluminum cables have been upgraded in size, to match the current carrying capacity of the normal copper cables, then the only remaining difference is that copper withstands much more bending and coiling beforethe metal begins to "work harden," and some of the individual wire strands begin to break. In other words, the copper stands up to use better than aluminum. When buying booster cables, read the lables, and make sure that the maximum number of Amps, for which the aluminum cables are capable of carrying, is equal to or greater than the highest rated copper cables. Therefore, IF the copper clad aluminum cables are rated for the same current carrying capacity as copper cables, then there is NO difference in use between the two types.
What products does Cables Unlimited offer customers?
Cables Unlimited offers a wide range of cables for fiber optic installations and copper installations. Some of their products include power cables, coax cables, wireless tower cables, and patch cables.
What is the meaning of YFY and YWY in copper cables?
yfy means
What is electric cables made from?
Usually copper with plastic insulation.
Why isn't sodium used for overhead power cables?
The power cables are mostly built with aluminum and not with sodium because sodium is highly reactive. Aluminium on the other hand is reactive as well but it only reacts one and them becomes aluminum oxide. Sodium keeps on reacting therefore is too dangerous.
What are telegraph cables made of?
Many early telegraph cables were made of iron wire, but all modern ones are copper.
