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.
How is electricity transmitted in cables?
Electricity is transmitted in cables through the flow of electric current, which is carried by conductive materials, typically copper or aluminum. The cables are insulated to prevent energy loss and protect against electrical hazards. High-voltage transmission is often used to minimize energy loss over long distances, with step-up transformers increasing voltage at the source and step-down transformers reducing it for local distribution. This efficient system allows electricity to travel from power plants to homes and businesses.

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 overhead electric cables made up of aluminium and not copper?
Overhead electric cables are typically made of aluminum rather than copper due to aluminum's lighter weight and lower cost, which makes it easier to install and supports longer spans between poles. Aluminum also has a higher resistance to corrosion, particularly when treated with protective coatings, enhancing its longevity in outdoor environments. While copper has better electrical conductivity, the advantages of aluminum in terms of weight and cost efficiency make it the preferred choice for overhead power lines.
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 kind of wire is in PC ribbon cables?
Computer cables are often made of copper.
What is the element that is used for eletrical cables?
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.
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 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 electric cables made from?
Usually copper with plastic insulation.
What causes copper cable turn black?
Copper cables can turn black due to oxidation, which is a natural process that occurs when copper is exposed to air and moisture. This leads to the formation of copper oxide on the surface, giving it a black color. Additionally, exposure to sulfur compounds in the environment can also contribute to the blackening of copper cables.
