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.
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.
ACSR - Aluminum Cable Steel Reinforced
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
Cable reels are commonly made from steel or aluminum due to their strength and durability. Aluminum is often preferred for lighter weight applications, while steel provides more strength for heavier loads.
Aluminum conductor steel reinforced (ACSR) is a type of electrical cable composed of an aluminum outer conductor and a central steel core. The steel core provides strength to the cable while the aluminum conductor carries the electricity. ACSR is commonly used in overhead power transmission lines due to its high strength-to-weight ratio and conductivity.
It's strong enough, lighter than steel and cheaper than carbon fiber and titanium.
Aluminum is preferred to steel for handlebars because it is lighter in weight, offers better vibration damping properties, and is more resistant to corrosion. This makes aluminum handlebars more comfortable and durable for cyclists.
