Multiple stranded cable is used in transmission lines because the high voltage potential of each line causes the electrons to tend to run only on the surface of the line due to repulsion. You want to maximize the surface area of the line, hence the multiple stranded lines, so that you maximize the efficiency of the line. In fact, some transmission lines have a non-conductive core, adding strength while maintaining low weight.
Stranded wire is used in locations where there is mechanical vibration, such as your car or supplying power to a motor. Solid wire will mechanically weaken and break in conditions where there is continuous vibration.
To make the conductor flexible.
The minimum size wire that engineers spec for industrial and commercial installations is #12 and it usually is stranded not solid wire.
Either one can be used. Electricians prefer to use a solid wire and use the screw terminals rather that the pressure terminals. An eyelet can be formed with solid wire where as using stranded wire takes a bit more preparation to use. The stranded wire has to be wound tighter at the termination end. This is so that when the stranded wire is tightened under the screw terminal the wire does not splay into individual strands some of which do not get under the terminal screw. With some of the strands not tightened under the screw, this is the same as using a smaller size wire. The breaker feeding the receptacle is matched to a specific wire size. The now smaller wire size has a breaker greater than the ampacity of the wire. This could lead to overheating of the wire under full load and eventually cause a breakdown of the insulation. Once the insulation has broken down, the breaker will trip due to a short circuit. This wire will have to be replaced. This could involve opening the wall board to remove the burnt wiring should this happen.Most residential wiring is done with solid copper wire. In industrial applications, stranded THHN wire is used because many wires are run through conduits from service boxes and many different colors and gauges can be run to different locations. I personally would not use stranded in a residential application.
They should be the same but have different purposes. Stranded wire will flex easier than solid wire. And if one strand breaks there are sufficient numbers of other strands to continue the electrical current. When a solid wire breaks all connection is lost.
Need to know the wire # size to compute wire fill in conduits
Wire is sized by the amperage of the load. Without knowing what the load amperage,the voltage and whether the load is three phase or single phaseat the dock, an answer can not be given.
Stranded aluminium, with a steel core.
You would use a set of wire strippers made for stranded wire and proper size. If the strippers are made for stranded and solid make sure you use the size identifications for stranded not solid!
Appliances cords are made of stranded wire because of the flexibility of these types of cords.
Wire can be fabricated in two different forms. Solid wire refers to a single wire, while stranded wire is a wire which is made up of more than one single solid wire twisted together. A stranded wire is much more flexible, and less subject to breaking from flexing than a stranded wire of the same size.
The minimum size wire that engineers spec for industrial and commercial installations is #12 and it usually is stranded not solid wire.
Wire rope has finer strands and more of them. Because of this, rope is more flexible and stronger. Rope tends to unroll and stranded wire will stay bent.
no
Stranded wire is the choice as you have tight bends and a short run, solid wire isn't very good in this format.
They are interchangeable and stranded wire is slightly more expensive but is used for its flexibility. For fixed installations such as house wiring, solid wire is used. <<>> The interchangeability of the wire is based on the wire's insulation value. Automotive wire's insulation value is sometimes only 30 volts. Home wiring voltage value is 300 volts. Always check the insulation value of the wire before using it to make sure that it is within the range of the voltage that you are using.
Overcoat: Individual strands of tin copper stranded together & then covered with a tin coating. Topcoat: Bare (untinned) copper wire, stranded, then coated with pure tin.

bare copper is pure copper, while tinned copper is having light coating of Tin over it, preferred where soldering phenomenon is req. while the bare copper is good conductor then tinned copper.
