Usually it will be aluminum.
Steel.
SWB - Steel Wire Braid
Current in the single core cable would induce a magnetic current in the steel cable, though a transformer effect. This would heat the steel armored strands, and the circuit would increase more electrical power from the load supply point. The earthing of the cable glands would complete the circuit and the return current would flow in the earth bonding cable between the two points. This is called Eddy currents generated in the cable by the twist of the steel armored around the central core, current flowing in one direction
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.
Aluminium Conductor Steel ReinforcedOuter strand - AluminiumCenter strand - steelACSR having high conducting capacity usually used in overhead transmission line to carry high voltages.
The reason for this is that aluminum has much higher electric conductivity than steel, but otherwise its mechanical properties are much worse. Steel core actually carries a cable.
Compared to what? It's cheaper than steel, or aluminum, and so far it's cheaper than plastic.
It is cheaper and easier to manufacture than aluminum, fiberglass, carbon fiber or stainless steel bodies.
It is lighter, cheaper and will not rust, but still strong enough for handlebars.
Aluminum roofing may be cheaper and much more affordable than steel roofing however, steel roofing has proven to be much more reliable. It can resist different weather conditions and lasts much longer than aluminum.
Yes. A typical high voltage conductor is type ACSR - aluminum conductor, steel reinforced. aluminum conductor is wrapped around a central steel cable that gives it strength, the aluminum carries the current.
Steel is cheaper and easier to weld, and form into complex shapes. There are some cars made from aluminum.
Aluminum is the primary ingredient. With ink and sometimes various coatings. They are highly recyclable, it being cheaper to produce aluminum from existing metals than to create it from raw ore.
aluminum is cheaper, however it has also been shown that those afflicted with alzheimer's had high levels of aluminum in their brain tissue. whether there is a link or not, we do not know. however, i am going the route of stainless steel for that reason
ACSR - Aluminum Cable Steel Reinforced
Aluminum is easier and cheaper to mass produce than is steel. If you recycle aluminum, you get more money for aluminum than for steel only because manufacturers have for decades focused on aluminum as the cheaper way to manufacture so many things. Aluminum is lighter in weight; is more easily bent into desired shapes; can be easily separated from other metals (chemical process); and is easily shipped to manufacturing plants. As one example, in the earlier days, airplanes contained steel and were heavier, cost more in fuel, etc. Now, all airplanes are made of aluminum shells, are lighter in weight, use less fuel because it is lighter in weight, and all of the aluminum can be recycled. Same with automobiles.
It's strong enough, lighter than steel and cheaper than carbon fiber and titanium.
