What is alluminium conductor steel reinforced in electricity?
Aluminium conductor is reinforced by steel because it can give the strenght required to support the weight of the cable without streching the aluminium, which is very ductile. It gives a specific type of high-capacity and high-strenght cable, typically used in overhead power lines.
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.
Why is copper used as a conductor in transmission lines?
They are the most cost effective while maintaining good conductivity for electricity. Gold is the best conductor, but is too costly to make into wires.
What are composed of atoms A an oak tree B a steel cable C a human D all of the above?
D. All of the above. Hint: everything in the universe except a single atom is composed of atoms.
What type of energy does electrical cable have?
Electric.
What is the meaning of A2xwy in cable?
Aluminium conductor. XLPE. Nonmagnetic armour, PVC outer sheath
Can aluminum be used as a gland plate?
yes,for non Ferrous application and in the places where a single core cable is used. Else it not required to use a Aluminium gland plate
How deep do you bury 120v wire?
Minimum coverage for non vehicular areas; for conductors or cable not having a metal sheath or armour, under 750 volts, the required depth is 600 mm. For conductors or cable having a metal sheath or armour, under 750 volts, the required depth is 450 mm. Minimum coverage for vehicular areas; for conductors or cable not having a metal sheath or armour, under 750 volts, the required depth is 900 mm. For conductors or cable having a metal sheath or armour, under 750 volts, the required depth is 600 mm.
What is meaning of a2xway cable?
a- aluminium 2x- XLPE insulation wa- non mgnetic round wire armour y- pvc outer sheats
Why armour HT XLPE power cable required to Earth?
because when ever fault current occurs then the cable wont get damaged due to cable armored earthing to the gland for fault current to pass through groung
Difference between metallic sheath and armour in cable?
The metallic sheath prevents the ingress of moisture, while the armour protects the cable from damage from foreign objects.

What is AAAC cable?
All Aluminium Alloy Conductar
Why are copper wires used in as connecting wires?
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
What is the difference between single core and multi core wires?
Single core has one single piece of metal wire, maybe copper or aluminium, with insulation around it. It is not very good if you want the cable to flex and bend as it is more likely to just bend and stay there in the new position. Multiple-strand cable has lots of thin wires and this makes it more flexible and likely to spring back
What elements make electric cable?
Copper and aluminium are used for electric cables.
Why aluminium cable cost less than copper cable?
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
