Flexibility is the main advantage of stranded wires; however for high frequency AC (i.e. radio frequencies), stranded wires increase the surface area, minimizing the skin effect (i.e. high frequency current avoiding the core of a wire, increasing its resistance at that frequency). This is not an issue at typical power frequencies (e.g. 60Hz) as the skin effect is still insignificant at those frequencies.
The advantage of stranded wire over solid wire is the flexibility of the conductor when it needs to be bent. At a certain size, solid wire would be impossible to pull into conduit or make terminations in cabinet junction boxes.
It has to be kept in mind that the more you flex or bend copper conductors the harder the copper becomes. A good experiment is to take a #14 solid copper wire and a #14 stranded piece of copper wire and start bending them. Count the bends it takes before the solid wire breaks and compare it to the number of bends it takes to break the stranded wire.
Stranded wire because it is made up of a number of smaller strands in the conductor, allows this conductor to be flexed more than solid wire there by making it easier to work with.
By bundle conductors, I am assuming that you mean stranded conductors. If you actually mean bundles of wires, then the bundles could be either stranded or solid and your question does not make sense. Stranded conductors have two main advantages over solid conductors. The first is flexibility. Stranded conductors are much more flexible than their solid counterparts. The second main advantage is skin surface area. Alternating current tends to travel towards the outer skin of a conductor. This is known as the skin affect. Stranded wire has a lot more skin surface area than solid wire does. There may be more advantages, but these are the two I could think of off the top of my head.
The most common way of making an electrical connection is with a device called a wire nut. Solid wire connections should be twisted together with a pair of pliers before installing the wire nut to hold the splice tight. Twisting stranded wire together with a pair of pliers does not allow the wire nut to grip the wires as tight as it should. Stranded wire should be held together side by side (in parallel) and let the wire nut twist the wires together to make a solid splice connection.
In a transmission line, voltage is stepped up to a very high value. This is so as to take advantage of lower line current and smaller conductor size. At these potentials1, however, like charges repel, so most of the current flow is along the skin of the conductor. Stranded conductors, even wound wire over insulating rope, is more efficient, and more cost effective, than solid conductors.--------------------------------------------------------------------------------------------------1 Actually, this effect occurs at any voltage, but it is most notable at the very high voltages used in power line transmission systems.AnswerStranded conductors are used because of their flexibility compared with solid conductors. Normally, transmission lines consist of a steel-wire core (which provides strength) around which are wound stranded aluminium conductors.
white wires are neutral. green wires are ground wires.
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.
RM-Conductor of Multiple stranded wires of circular cross section.
Splice uses stranded wires while joint uses solid wire.
The electrical terminology for this device is a wire nut. If the two #10 wires are solid, twist the two stripped ends together with pliers and apply the nut to the wire ends. If the two # 10 wires are stranded lay the two stripped ends parallel to each other and apply the wire nut. Do not twist the stranded wires together.
Stranded conductors are made up of many smaller solid conductors. In order to bunch the solid conductors to make the stranded wire they have to be held together. The simplest way of doing this is to twist them together. Once the solid wires are twisted together they are drawn through a machine that applies the insulation coating which holds the solid wires together. The final result is a insulated stranded conductor that has good flexibility. With this flexibility multiple stranded conductors can be easily be drawn through conduit systems that incorporate up to four 90 degree bends between junction boxes.
Probably "non-stranded" ... the wire is a single solid conductor, not a bundle of much thinner wires.

Wires are made of copper and sometimes coated with silver for use at frequencies above 1 GHz. Wires used on overhead power lines are usually stranded aluminimum with inner strands of steel.
Two basic types of wire are used: solid and stranded .Solid wires are single strand conductors.Stranded wires are the most common and are made up of a number of small solid wires twisted together to form a single conductor.

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.
No Wires.... Disadvantages = 1) Less secure 2)Slower
