Q: On page 44 of the April 1997 issue of Cabling Installation & Maintenance, you responded to a question concerning stranded versus solid cable attenuation. Patch cords are the best example of this. Each has distinct advantages, with the right choice for an application depending on the specific project details. I'm looking at this and thinking why have such heavy cable especially since I'm running about 10 ft. A stranded cable is composed of several small wires grouped or wrapped together to form a larger conductor. I had suspected about 10% to 15% attenuation, but had never heard any specific numbers. Depending on your application, you should restrict their use to short distances. I think the problem is probably that it's ribbon cable, not that it's stranded wire. Solid and stranded wires see frequent use in electrical equipment, such as cable assemblies and wire harnesses. I am getting my parts list together for wiring the house with cat5e. When i opened up speakers the wiring from speaker connections to crossover and speakers is 20 gauge wire. Plus, anything over 5M (in general) should always be solid due to the extra resistance of stranded wire over its length. I have known since day one that stranded cable would have more attenuation than solid cable because of the "skin effect" in high-frequency transmissions. It looks sharper, and usually has 3 prongs that are offset for the conductor to . Although both types within each category are made to meet the same cable configuration and electrical performance specifications, their physical properties place different restrictions on cable segment length . Solid conductors are more likely to break if subjected to frequent flexing than stranded conductors. As a result, you won't have to replace your stranded cables as often as will be necessary with solid cables. It's best to keep lengths of stranded patch cables under 6.0 metres. Most patch cables are made of stranded cable. Stranded Category Cables have a higher attenuation than solid category cables. Trying to push in stranded wire is frustrating. IMO anything larger than #12 should be stranded. Stranded cables almost always use heat treated materials, which cause the skin of the strand to be stronger than the core. Because solid equates with more rigid, it is best suited within an application that doesn't require much flexibility. The difference is stranded has a higher loss factor than solid center, it is however more flexible. in-wall). No matter if your cable is Cat3, Cat5, Cat5e, Cat6 or Cat6a rated, it is also classified as either "solid" or "stranded". So stranded cables experience 20-50% more attenuation than similar gauge solid conductors. The Cat5e easy RJ45 connector provides an easy to see wire pattern. Compare wire and cable conductor strand types, quickly and easily with our clear diagrams and simple explanations. Be sure you use the correct end for the wire if you want a reliable connection. All cable runs are indoors--between 30 feet and 150 feet maximum--and the cable is Helix/Hi-Temp, 4-pair. unread, Oct 31, 2015, 8:43:00 AM 10/31/15 . Cables as per BS 6724 shall meet the . The video illustrates the basic difference between solid and stranded wire conductors.Solid wire conductors are made from single piece of solid wire, whereas. The stranded variety is a more viable . patch cables). There is a difference, and you should get patch panels, ends, and cable that are all either stranded or solid. This was done as part of the NetDay `96 project. Stranded cables can withstand an incredible amount of vibrations and flexing without fatiguing and eventually breaking. Solid Core Cable This type of cable uses one solid copper wire per conductor and is used for permanent infrastructure links between two wiring centres or between a wiring centre and a wall box. Instead, stranded cable is typically used to create patch cables. They are also extremely flexible. The solid Ethernet cable is one solid wire of copper while the stranded ethernet cable is a serial (normally 6 to 18) of small wires twisted to form a simple wire (much like a rope) with the same diameter as a solid wire. Note that in many areas, plenum rated cable has to be used in dropped ceilings and the like. It has a lower attenuation and is less costly than stranded cable, however it is designed for horizontal and vertical structured cabling […] Flexibility - Solid cable is relatively stiff and resistant to bending, while stranded cable is pliable and bends easily. So in general a 14 Ga stranded wi. It is tougher than a stranded conductor, but rigid and less flexible than a stranded conductor. Solid vs. Stranded Resistive Wire. Instead of one solid copper wire like solid cable, stranded cable has multiple copper strands that form one wire. Fire Wire Solid vs. Stranded. Skip to first unread message . And here is the kicker for DC. It's best to keep lengths of stranded patch cables under 6.0 metres. The affect you want to know here is attenuation. And the more strands a conductor has, the greater the flexibility. The RJ45 terminators have a better, and more flexible and complete connection to stranded wires than solid wires. That is where stranded wires are use in areas such as patch cable that may get moved frequently. I will answer in general skipping complex issues like high frequencies etc. Of course monoprice.com is my friend. What does stranded do that solid doesn't. Sent from my iPhone using Tapatalk Solid cables are tougher than stranded conductors, but they are less flexible. - If you need a great deal of heat within a limited amount of space, you may wish to coil the wire. All good speaker cables sound the same, including plain ol' cheap lamp cord. system June 5, 2012, 5:22pm #1. Actually solid wire has better electrical characteristics, stranded is normally used for patch cables and stuff that will be handled a lot. This type of cable is slightly more rigid, but has a very distinct advantage over stranded cable: It can carry a much stronger signal than stranded wire. Stranded cables are much more flexible and can withstand more bending compare to rigid solid conductors that can fail if flexed too many times. Solid wire in heavier gauges are impractical for this very reason. Concentric Strand A concentric stranded conductor consists of a central wire or core surrounded by one or more layers of helically laid wires. For lower frequencies it isn't really a bid deal, but anything over VHF-HI it can start to become a factor depending on the length. Solid cables consist of a single solid strand of metal wire. Note: There are different C8P8/RJ45 ends for Solid and Stranded wire. Solid conductors are constructed of one, single piece of metal. They are designed for longer distance horizontal and backbone cable runs, PoE (power over Ethernet), and HD applications. An example of solid core speaker cables would be the Alpha Core MI 1 which is a single ribbon of wire for each polarity. After using #10 stranded I hate going back to #10 solid. Stranded cables are flexible because of the stranding structure. In low voltage cabling, we hear the terms solid and stranded on a regular basis. Skin Effects. In contrast to the keystone jacks above, the actual RJ45 jacks that go on each end of a . - If you need a very heavy duty heating element, stranded wire can be twisted into a cable with a larger cross section than a single strand wire. 5y. These cables are used in permanent and semi-permanent installations. 4. It works wonders when paired up with 1000ft Cat5e plenum cable to offer better performance. Stranded cable is a type of cable where the wires inside the cables are made up of multiple smaller wires constructed together. Solid cable would not stand up to the abuse that a patch cord can take, so patch cords are made out of stranded wire. The cable itself is more flexible, and rolls up well. This type of wire's core is made up of non-conductive material for insulating. In regards to low voltage dc communication, why would stranded wire be spec'd vs solid wire. This means solid copper Ethernet cable is designed for installation in spots where the cable is not going to be stressed by handling. Unfortunately, the installers were supplied patch-cord stranded cable, not solid wire--16,000 feet of it pulled into five buildings. EZ-RJ45 Cat5e Feed Through Connector - 8P8C - Solid & Stranded Cable. Look at Table 8 Chapter 9 NEC on the right hand side of the table. The best wire and cable for your needs will depend on a myriad of factors - temperature, internal/external conditions, load and application requirements. 2.5, 4, 6, 10 mm^2.The former 3 are stranded or solid, the latter 2 always stranded.It's very difficult to bend the thick wires when they are solid, so they stopped producing solid 10 mm^2 wires, used to wire old-fashioned fuses and circuit breakers.The ampacity of these conductors is 10,16,20,25,35 Stranded: the copper wire is a bundle of several smaller copper strands that are roughly equivilant to a single 20-24 AWG strand. Since attenuation is higher in stranded cables than in solid cables, stranded cable runs should be kept short to lower the chance of introducing even more attenuation into the system. Stranded cables tend to have more performance disadvantages than solid cables. system June 5, 2012, 10:37pm #3. The main, distinct difference between these two is the overall flexibility. Basically solid wires have less resistance per 100 ft than stranded cable (i.e. This Solid: the copper wire is one 20-24AWG strand. Solid wire (24 gauge) is good for use as jumpers in solderless breadboards. Because these cables are more flexible than solid conductors, they are excellent for portable uses and applications where repeated flexing is common. Virtually all of the "behind the walls" wiring should be solid conductor. LG mini split wired wall thermostat stats 18/3 stranded non shielded wire. Solid wire is cheaper as compared to stranded wire due to its complex process of production. Stranded cables are easier to route in comparison to solid cables. that have 3/4" conduit to device with only a 18/2 cable inside. Since I am buying a spool of solid cat5e for the in-wall runs, does it make a difference if I also use the solid cabling for patch cables from the panel to the switch? Stranded copper Ethernet cables have their place too. The stranded wires combine to form a conductor with the same diameter as a solid cable. I plan on adding some in the wall network lines to my new home. Started reading people opinion on strand vs solid and was curious about other folks results. Diagram courtesy cableorganizer.com. Both solid and stranded wires are normally given a gauge designation indicating its equivalent diameter. Solid cables offer superior and more stable electrical properties over a wider range of frequencies than stranded wire. Also learn why and when you should used these types of cabling.Find more informa. Solid wire does not suffer this loss and that is why solid wire is the best conductor of electricity. Even though the cables are bent, cables can't be easily harmed since each . Use stranded wire for everything else. A cable that has a single stroke of copper wire per conductor is termed as solid cable. Solid wire holds its shape, so you can route wires along a path and they'll stay there. You can often see stranded cable also be referred to as stranded wire. DC resistances are given. So‚ the stranded cables are well-suited for applications that require flexibility and movement. There's $12- $14 savings between solid and stranded per 500'. can certainly sound different, because they can add coloration. They have a more rigid structure and are more likely to break under the stress of frequent flexing or bending. And the solid wire has lower resistance than stranded. It's been shown that stranded cable has anywhere between 20 - 50% more attenuation than solid cables at longer distances. Choosing between solid and stranded conductors is one of the first decisions made in a custom cable design. We have been using stranded #10 AWG MC cable for the last year or so. You can generally only find stranded in pre-terminated patch cables because it is nearly impossible to do a proper crimp on the end by hand and still pass all the EIA/TIA tests. The most basic difference is obvious when you peel back the jacketing and look at the […] BTW, *badly* designed cables (usually the most overpriced ones!) have solid insulated bare copper conductors. Strand count can also impact cost - the more strands that make up a wire, the greater the cost. Solid Solid cables have a core made from a single metal line, typically copper or copper-clad steel. Solid cables are relatively rigid and can stand up to bending while stranded cables bend easily and are pliable. Solid cables can withstand being pulled through wall jacks and walls while stranded cables are more probable to distort and shred. Within each of the 8 individual wires, there is a solid piece of copper wire covered with a thin PVC jacket.
