The Advantages and Disadvantages of Installing Bare and Tinned Copper Wire
Wires and cables are specifically used to transmit energy. Gold, silver, copper, steel, and iron are known to be good conductors of electrical energy. Electrical energy is used by everyone since most of the technologies that man had invented are relying on electrical energy to operate. Man is also using electrical energy in his daily tasks. It had made his job easier. Electrical energy can be a source of heat during the winter months. Since the discovery of its use, different types of cables and wires have been invented and innovated for the reason that the various uses of wires and cables had also expanded. Telecommunication systems are using a cable to transmit information from one place to another. One of these wires that have been used by industrial companies and homes is bare and tinned copper wires. These types of wires are used by many for various purposes. It is a type of copper wire that is without an insulator but is coated with tin to prevent fraying of the strands. It is known to be non-corrosive and it is also a great conductor of electricity. Its use in settings where there is constant exposure to moisture. It used primarily in overhead power sources where it cannot be reached by human hands.
Bare and tinned copper wire is also used to ground electrical systems. When used in this type of setup, it should not be used to transmit electric current due to the fact that it is lacking in insulation and to prevent electrocution of those individuals who will accidentally touch the wire without any protection. Electrocution can be fatal. This type of wire is available in various sizes and tempers. It can also be used on other purpose but one should be very careful with it especially if it is used to transmit electricity no matter how low the voltage will be.
Bare and tinned copper wire can be purchased in solid or stranded type and in soft or hard-wired. You can purchase this type of wire by the meter or by the spool. You need to measure the total length of the location where you will install this type of wire to prevent shortages or excesses of the wire you purchase. You need to browse various sellers online to compare the prices offered by these sellers. If you intend to buy a huge quantity of wire, choose a seller that offers free shipping to their customers who order materials from them by bulk. You also need to check the credibility of the seller before purchasing especially if you are transacting with them online. This is to ensure that the wire you have purchased is manufactured within the standards specified by the NEC and other government agencies that are designated to ensure the safety of the wire users. Your failure and of the seller to follow the guidelines provided by these agencies may make you liable in instances that there is an accident due to you or the seller’s negligence. You can also ask the seller for other customized services such as cutting the wires in your desired length.
Solid bare copper wire, which is also known as ground wire, is a stock item for WesBell. Our Romex®, which is a type of Electrical wire, comes with a standard ground wire in all of its cables. If you’re running separate THHN electrical wires then you might need some of our solid bare copper.
Solid Bare Copper
Solid copper is an uninsulated copper wire used for grounding. It comes in most electrical cables such as Romex® and UFB cable as a ground wire. MC cable comes with a ground wire as well, but it has THHN insulation in a green color to designate it as a ground wire. The reason it has insulation is so that it can be run outdoors and in conduit without the scare of moisture hitting the bare copper wire.
Our bare copper electrical wire has a military approval code of AA59551 on each and every gauge size available. Solid copper #8 is the most popular AWG size used based on the volume of electrical wire here at WesBell Electronics. Some customers order our solid bare copper for arts and crafts projects as a hanger or basket handle along with many other variations.
We have 100′, 500′ and 1000′ spools available for purchase online or you can call our customer service representatives if you need something in between or a higher quantity for a better price. We offer free shipping on all of our electrical wire and cable on orders over $500 so that you don’t have to worry about figuring out the best shipping rate.
AA59551 Mil-Spec Approved Bare Copper Wire
Mil-spec approved wires are one of the toughest kinds of wire that you could use for your electrical connections. The word “mil-spec” is not just a word; it stands for “military specifications approved” which means that this type of wires is what the military uses for their high-end computer connections and other military equipment. The AA59551 mil-spec approved wire is one class of copper wire that serves two general purposes. It can serve as a ground wire for electrical wires and it can also be used to be the cable for ground wires. The most common material that is used for this type of wire is copper. Specifically, manufacturers call these wires as made of bare copper, i.e. wires that are made of solid copper. The advantage of using bare copper wires for electrical wire or ground wires is that they generally have no insulation. You also need not worry about the size because they also come in the size range of 26 AWG to 2 AWG – a wire gauge for all the sizes you might need.
As was said earlier, the most common use of solid bare copper wire is for grounding since it has virtually no insulation at all. AA59551 mil-spec approved wires can come either in a solid version or a stranded version. Although generally, manufacturers produce a much more solid version of bare copper wires than the stranded version because of the higher demand. This means that if you intend to have a stranded version of solid bare copper wires, it would be best to call or e-mail the manufacturers first so they could provide you a quote of this version. Solid bare copper wires are also used as an additional conductor for cable wires such as in MC cables. The solid bare copper wire, as a ground wire, will usually be damaged first when moisture, gas, oil, and other solvents hit the cable, so if you are going to make wires yourself, it would be good to add a strand of bare copper wires in those wires.
AA59551 mil-spec approved wires are also qualified to have a tin coating. If the bare copperware is generally used for grounding, the tinned copper wires also serve the same purpose with just a little difference. First, tinned copper wires have tin. This tin coating makes the soldering process of the wire a whole lot easier. This is because the soldering lead has higher adherence to tin than to bare copper. The high adherence of soldering lead to tin makes tinned copper wires much more recommended for those who need to solder wires but are not actually experts. Examples of these people are those who are up for a soldering project but are not exactly majoring in electricity-related courses. Pretty much like it bare copper counterpart, the tinned copper also doesn’t have much insulation and have gauged from 26 AWG to 2 AWG. The conductive and non-insulating properties of this wire also make it AA59551 mil-spec approved.
3 Types of Bare Copper Wire
1. Soft Drawn Bare Copper
Soft drawn bare copper wire is the most popular version and probably what you’ll find when searching for the bare copper or solid copper. The term soft drawn explains it pretty well because the copper is solid but soft enough to bend and wrap around corners. Bare copper is used for grounding and overhead drive transmission installations.
2. Hard Drawn Bare Copper
Hard drawn copper wire has a coating over it to give it a bit of protection and to strengthen the wire. You’ll notice when holding it that the soft drawn is much easier to bend than the hard drawn. Sometimes a stiff wire is easier to install when the application isn’t bending around corners. Both types of bare copper are approved with Mil-Spec AA59551.
3. Stranded Bare Copper
If you require superior flexibility then you should consider using stranded bare copper. Using multiple thinner strands bundled together will give the wire more movement and bendability which may be helpful in some situations. All three types of bare copper conduct the same amount of electricity. The differences lie in the type of installation and preference of the user.
