What is purpose of the steel core in some large overhead conductor?
The wire you refer to is ACSR. Aluminium Conductor Steel Reinforced. The steel core is used to give the wire structural strength. When the conductor is spanned across great distances between poles or towers the total weight of the conductor between spans would be too much for just the aluminum wire to support. The steel center core is also known as the cables messenger.
Can you use aluminum wire for 240 volts 20 amp 200ft?
Yes you can. This is what ACSR over head wiring is. Aluminium Conductor Steel Reinforced.
What is the current carrying capacity of ACSR conductor at 45 degree ambient?
To answer a current carrying capacity question the size of the wire has to be stated.
What lines send the electricity over nationwide network?
If you mean conductors instead of lines the wire is ACSR. Aluminium Conductors Steel Reinforced.ACSR is a concentric-lay-stranded conductor consisting of a single core wire or a stranded steel central core with one or more layers of stranded aluminium wires.
Are copper wires and not steel wires used in electric circuits although both copper and steel are electrical conductors?
Steel is not used as an electrical conductor because, although it is a conductor, it's not a very good conductor -as is copper and aluminium, for example. A steel-wire core is used, however, to reinforce aluminium conductors on transmission tower lines
What is wire factor of All almunium steel reinforced conductor size 0.176 S.W.G?
What is wire factor of almunium conductor steel reinforced size 0.176 S.W.G?
Is steel spoon is conductor or insulator?
A steel spoon is an excellent conductor of heat.ANSWER: Conductor
What size insulated wire can handle 20kV?
Insulated wire is not used for high voltage installations. For transmission installations ACSR is used. It is Aluminum Conductor Steel Reinforced cable that is strung from tower to tower. The insulation comes from the separation of the conductors and the amount of insulators that support the wires from the tower frames. Common insulators have a rating of 5000 volts. To get to higher voltages they are strung together boosting the insulation rating by 5000 volts each time another insulator is added to the string.
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 type of bindinwire is used for binding of steel?
The most highly recommended type of binding wire used to bind steel is stainless steel binding wire. Annealed steel wires and galvanized steel wire can be used as well.
Why is aluminium suitable for making electrical wire?
Electrical transmission wires are made from aluminum and steel. The cable in the electrical trade is known as ACSR. The letters stand for aluminum conductor steel reinforced. To keep transmission costs down, long spans of cable are used between towers. To use copper in such spans would require more towers to support the heavier wire conductors. The straight use of aluminium would not work either because of the softness of aluminum and if flexed sufficiently would break. A steel messenger wire with the aluminum conductors wrapped around it fit the bill for a light weight and strong cable. Due to the steel messenger wire installed in this type of cable, it is able to span great distances between towers and high voltages can be applied to it because of the wire spacings and distance between other cables on the same tower.
What are high voltage electric wires made of?
Primary utility wiring uses an ACSR cable, (Aluminium Conductor Steel Reinforced). The multiple strands of aluminum wires are wound around a center steel cable. The steel center is used to allow longer spans between poles or towers. Ordinary aluminum wire can not be long spanned because its weight would break the wire. All other high voltage wiring is done with different insulation thicknesses dependant upon what the voltage is. The higher the voltage the thicker the insulation. Insulation of the wires stops when the conductors carry kilo voltages usually above 5000 volts.
