This article will take an in-depth look at stranded wires, braided wires, and wire strands.
The article will bring more understanding on topics such as:
Stranded wire is formed by thin strands of wire that are twisted, wound, and bundled together to form a cable-like, solid wire. Depending on its construction and fabrication, the bundles may or may not be enclosed in an insulating material such as PVC.
Due to its flexibility, stranded wire can be configured to meet the needs of a wide variety of applications. It is ideal for joining electronic circuit components in confined spaces where there is limited room. Aside from being very flexible and malleable, stranded wire has superior strength and resilience, which makes it difficult to break.
Braided wire is multiple strands of flexible wire that is wound on a spool in circular patterns around a core. The weaving process brings the various wires together and shapes them into flexible, strong, round braids. Its size is determined by the number of carriers on the braiding machine, which can vary from 16 to 48.
The shielding is made up of numerous tiny wires tightly woven in a standard mesh tabular formation around the conductor. In some designs, it can be flattened to achieve the desired width. A thin insulating layer covers the braid and other internal components of the cable.
A wire strand is made of two or more wires that are wound around a single center wire., which are then wound around the core. Wire strands are identified by two numbers, with the first number indicating the strand count and the second representing the gauge of each strand.
Wire strands can be wound in varying numbers of configurations. The higher the strand counts the more flexible the wire will be. The strands can be made from stainless steel and precious metals like tungsten, gold, and silver.
Stranded wire is widely used in several applications due to its anti-interference properties, long transmission distance, ease of wiring, and low price. They are used for wiring circuit boards, headphones, computer mouse cables, controller cables, and musical instruments. The flexibility and ease of stranded wire is one of the main reasons it is found in residential applications.
The center of a stranded wire is made of a resilient conducting material that contributes to sits high tensile strength. Aluminum makes up the external bundling wires aids in improving conductivity, and makes the conductor flexible.
A single solid conductor will not be as flexible as would be a stranded conductor and transportation would be challenging. Consider transporting a single conducting wire of 100m. A stranded conductor can be coiled and packed easily for transportation.
The following are some known facts about stranded conducting wires.
Braided wires are used as electromagnetic shielding noise reduction cables, and satellite cable connections. The ability of braided wire to shield interference and block electromagnetic interference (EMI) has led to their use in a wide array of applications.
Wire braids are manufactured from copper, which can be bare or braided depending on the application. Silver- or nickel-plated copper are common, with in-coated copper wire used because of its conductivity and resistance to corrosion. The braided wire begins as multiple strands of thin wire that are wound on rotating spools that rapidly rotate to form patterns around a core creating a weave that shapes the wire thing into a flexible and sturdy braid.
The size of the braid of wire depends on the number of carriers the machine has. Usually there are sixteen, twenty four, or forty eight carriers. Each carrier has a bobbin with as many as sixteen strands of wire. Construction is named using three numbers (such as 24-4-36) where:
A plain braided wire starts as a round braid and is made flat by a force roller on the capstan. A capstan is a huge roll that pulls the line through the braiding mechanism. A flat braid is as stretchy and strong as round braids, but it has a greater surface extent, which means it has less resistance when an electric current passes through it.
The wire strands are wound concentrically in a helix.
Stranded wire, also referred to as wire strand, is made by stranding together individual wire filaments into strands and wrapping them helically around a core to make rope. It is made of wire filaments, strands, and a core. Strands are multiple wires arranged helically and symmetrically with uniform pitch or lay.
Wire strand is flexible, strong, and ideal for support and lifting mechanical loads. It holds up in the face of tension, vibration, and movement. When made from the right metals, it can be a conductor of electricity and useful in telecommunications.
The thickness of the strands of wire strand makes it customizable. When the diameters of the wire are small, the wire strand is more flexible. When the thickness of the wire’s diameter increases, the stiffer the wire strand becomes. Some of the industries that rely on stranded wire products include aerospace, electronics, defense, automotive, chemical, communications, healthcare, and security.

Although the numerous small strands of wire are bundled together to make a flexible conductor, the strands can be arranged into a variety of symmetrical patterns to meet design standards.
This is a common wire arrangement. Concentric stranded wire is a conducting material that consists of a middlemost wire encapsulated by one or more coatings of helically arranged wires. The conductors are organized in concentric circles, with each layer after the first one consisting of six wires more than the previous layer. Concentric stranded wire arrangements decrease the necessity for filler material. The wires are bunched together firmly to uphold the wire’s form and help increase conductivity.
These stranded wire arrangements don`t have an exact geometry. The strands are bunched and some poised together in a similar direction. The alignment of wires is twisted together firmly to ensure they stay uniformly packed. The acceptance of bunched stranding entails their toughness and elasticity. The high malleability ensures them best for bending around constricted corners.
Rope stranding sets wires together into numerous small bundles. Individually, each component strand is self-stranded and then organized into concentric rings to create a rope-like cable. The roping improves flexibility. This permits greater movement in use that requires frequent moving in multiple directions. Bigger gauge wire can be used with rope strands, and it adds to the toughness and functionality of the wire.
A compact stranded conducting wire is often used where lesser diameter applications are needed. The separate strands of a bigger, round conductor are organized in layers in the same way. Once the bundle is set, they are compressed to take out all of the trilateral airspaces between the strands. The result is a much less finished conductor without airspaces and yet with the same extent of conductor cross section.
The most common resources used for braided wire are tinned copper and silver-plated copper. Other materials that can be used are nickel-plated copper, gold-plated copper, pure silver, pure nickel, and gold alloys.
Electromagnetic waves range from signals bouncing to and from our phones, radio waves, and even natural sunlight. Data mediums require shielding to reduce data interrupts and losses. Specially woven metallic wires deflect the interferences so that data transfers are smooth.
Foil shielding is a metal tape used as a substitute for braided wire. It offers exceptional protection against high frequencies, is less expensive compared to braided shielding, and folds and breaks because it does not have lattice reinforcement.
Strands are the products of the stranding procedure, where wires or cables with a certain cross section are arranged and twisted together to create an electric conductor with a greater cross section. The process improves mechanical flexibility, vibration resistance, and prepares strands for stranding or padding and heathing.
Layer length and the twisting direction depict the strand definition. There are two possible twist orders: left-hand and right-hand lays and are usually shown with S and Z respectively.
The strands can be separated into three different categories depending on their structure:
Bunched strands are packs manufactured in one phase with single wires or huddled multi-wires. The structure is uneven and the lay direction could be S or Z. This type of strand has the position of each of the individual wires not clearly defined. The exterior surface is irregular and the wire diameter and roundness are usually not accurate. This type of strand is not appropriate for a thin-wall lining process. This bunch is suitable for bendy or stretchy cords, building cables, and control cables.
This type of strand has a steady regular construction having a symmetric number of wires of (1 + 6 + 12 + 18 +24 + 30). The conducting material has 7, 19, 37, 61, or 91 wires. Concentric strands can be separated into two categories, namely: true concentric types and unilay types. True concentric kinds have different lay orders of the consecutive layers from inside to outer layers, while unilay types have even lay directions. Common characteristics of all concentric conductors are the accuracy of the outer layer surface and the accuracy of the conductor’s diameter. This strand is mainly suitable for thin-wall insulation processes that comprise of high-quality insulation materials.
In this type of strand, there is a regular arrangement but there is no symmetric number of wires (2 + 8 + 4; 3 + 9+ 16) as in the concentric strand. The outside layers are regular around a central wire and the outside surface is regular. These strands are appropriate for thin-wall insulation.
Semi-concentric and concentric stranded conductors can be compressed with rollers or dies to get a very smooth exterior surface with the least conductor outer diameter, thereby reducing the insulation material to be used in the insulating process.
The term strand refers to the mean of an assembly of 7, 19, or 37 clusters or concentric strands in an even construction set. These are referenced as rope lay bunch stranded or rope lay concentric stranded.
Stranded and solid wire are differentiated by their advantages and drawbacks. An evaluation narrows down the adoptions based on how the specific wire attributes relate to their intended use and the project necessities. A user must first consider their application’s requirements for climate resistance, flexibility, and toughness to splitting, severing, or failing. They then choose the most appropriate wire that will most closely meet the desired needs.
Some common differences of stranded wire and solid wire are as follows:
Solid wire is denser and thicker, which means a lesser surface area for dissipation. The numerous and thinner wires in stranded wire have air gaps and larger surface area with each individual strand, translating to more transmission of current and dissipation. When selecting between solid and stranded wire for housing wiring setup, the solid wire will offer greater current capacity.
Stranded wires provide a better elasticity, bendability, and flexibility, making them easier to go around obstacles than solid wires.
Stranded wires are very flexible and can withstand a lot more vibration and bending without breaking or failing. Solid wires require more frequent changes than stranded wires in applications with significant shifting or vibrations.
The single-core structure of solid wire makes it easier and much simpler to manufacture. Stranded wires require a more complex and cumbersome manufacturing process of twisting the thinner wires together.
For longer lengths, solid wires are a better selection because they have less electric current dissipation. Stranded wire will perform a lot better over minimal distances.
When it comes to comparing stranded and solid wire in terms of superiority, it is difficult to determine which is better than the other. Each choice offers different advantages in particular circumstances.
Foil shielding involves the use of metallic masking tape that can be made use of as a substitute for braided wiring. This kind of shielding offers exceptional protection against both high frequencies and other interfering signals, and on top of that, the associated costs are less than that of braided shielding.
The major drawback of this type of shielding is that it lacks a reinforcement of the lattice formation present in braided wiring and therefore the cables tend to fail as they cannot resist twisting and bending and cannot be laid down in a confined space.
Braided wire is handier and more adaptable because it plays a pivotal role in protecting the cable from both mechanical stress and EMI.
Braided wire only offers around 70 – 90% handling and adds bulk to the cable structure and this may not be best for applications that work with tight spaces or need 100% coverage. If shielded cable is required, consider doing a detailed background research on the task at hand. Usually, the consequences of selecting the wrong product are not worth the risk.
.Stranded wire has a structure that makes it flexible. It is handy when connecting electrical components in tight spaces since the wires can withstand constant movement. Companies use stranded wires for robotics, car doors, circuit boards, household appliances, and inside electronic devices.
Braided copper wire offers maximum flow of electrical current and is the best conductor of electricity, which is ideal for the operation of heavy duty machinery. Much like stranded cables, braided copper wire is flexible and pliable, making it easy to install in a wide variety of appliances and equipment. One of the major benefits of braided copper wire is its efficiency, which is comparable to coaxial cable.
Besides the numerous advantages that braided wire offers, these wires are known to be more economical than cables like coaxial cables. Because they can both transmit electrical power efficiently, they have specific characteristics which make them appropriate for specific home or business purposes.
While the solid wires are better suitable for robust appliances and outdoor uses, the braided ones are better for electronic devices and circuit boards. Braided wires are suitable for robotics and motor vehicle applications because of their flexibility and strength. When purchasing this variety of copper cables it should be confirmed that the suppliers are legitimate and have a solid reputation.
Conducting cables should only be procured from companies that use top-of-the-line raw materials and have been tested for safe use in home appliances or industries. Users can confirm the credentials of the dealers by checking for web reviews about the business organization and going through customer feedback on purchased products. This will provide insight on which manufacturers can supply safe and relatively cheap braided wires. Copper wires are still the most favored electric conductor when it comes to making electrical devices and appliances that require flexible and durable wiring.
In dealing with reinforced and prestressed concrete bridges, the prestressing system is made up of a wire, strand and connecting parts, anchorage, force stressing jacks, corrosion resistance, and ducting just to mention a few. The wire diameters usually range between 5 and 7 mm with a least tensile strength of around 1570 N/mm2 and are able to carry forces up to 45 KN. A strand is an assembly of numerous high strength steel wires twisted together. Anchorages are mechanisms used at all ends of the tendons, and the resultant forces are transferred into the base concrete by an anchorage mechanism after being coursed through by the stressing jacks.
A solid cable is constructed with just one strand and sometimes the core of a wire that has non-conductive matter for insulation. This kind of cabling is used for residential electrical wiring, wiring for laboratory breadboards, and other circumstances where wires are not required to be constantly moving about in the system.
Stranded cable is made up of a number of tiny gauge wires that are usually insulated and compressed with covering materials that cannot conduct electricity. This type of wiring is characteristically used in situations where the wire must be made to crawl about into cramped spaces and its strength will be put to use. It is yet again used in applications where there is substantial moving about, flexing, or vibrations of the working parts. Typical examples where such cabling is adopted include speaker wiring, headphone wires, appliance cables, etc.
There are circumstances, like the case of outdoor overhead electric cables and other heavy duty appliances, where the cables are exposed to corrosive materials, back and forth movements, and extreme weather conditions. Engineers have settled for solid cables as the best in such situations.
Solid cables are favored because they are usually more affordable than the stranded assortment and have relatively cheaper manufacturing costs. This type of cabling is simple and is very resistant to corrosion and mechanical wear and tear. Singular but thick strands of cables are relatively resistant to occurring threats and very easy to produce. Solid cables have a much more compacted diameter in comparison to stranded cables. This reduced extent does not lessen the current conductance ability of solid cables. In addition, the solid cables are usually not as vulnerable to failure as a result of deterioration and corrosion.
Though single solid cables have plenty of laudable features, they also have a number of drawbacks. One of the main challenges associated with solid cables is that they are commonly only sold in small volumes. If there is continuous flexing or vibrations, the cable will eventually wear down and fail, creating the necessity for a replacement. Therefore, solid cables are usually not optimal for usage in robotics and vehicles requiring significant movement. If the cable happens to be bent into obdurate shapes, the solid cable will not have the suitable amount of fortitude and malleability to remain intact.
Stranded cables are simpler to pack in tight spaces in comparison to solid cables. They are also extremely flexible and bendy. Stranded cables can resist a large amount of vibrations and back and forth flexing without wearing down and failing. As a result, users will not have to change the stranded cables as frequently as will be required with solid cables.
Stranded cables are good but far from perfect. Their diameter is large yet they provide the same carrying capacity as solid wires. They are also a lot more expensive because their production costs are significantly higher than solid cables. The costs are relatively higher because of the complex manufacturing procedure that is needed to develop these complex wires. Stranded cables are very likely to fail as an effect of corrosion from capillary action. It is also worth pointing out that stranded cables are usually not best for preventing electronic disturbances. The air gaps between each wire amplify the “skin effect” made by the magnetic fields along the cable. Take each of the factors noted above into consideration before choosing either solid vs stranded cable for a household or business project.
In summary, there are various types of wiring used in the industries and home level appliances. Some common types of wiring are stranded wires, braided wire, and wire strands.
Stranded wire refers to thin bundled wires that are compressed and covered up in insulating material. Stranded wires are more flexible making them ideal for joining electronic circuit components in confined spaces where their bending and twisting capabilities can be put to use.
Braided wire is a jersey-like shielding built around a cable to shield the wiring from electromagnetic interference and to improve its mechanical strength. The shielding is made up of numerous tiny wires tightly woven in a standard mesh tabular formation around the conductor. In some designs, it can be flattened to achieve the desired width.
A wire strand is when wires are wound up concentrically in a helix. The strands are wound around a central wire then around the core. Wire strands can be wound in varying numbers of configurations. The more strands there are the more flexible the wire will be.
It is therefore imperative that a wire should be carefully selected depending on the job requirement and area of application.
