The answer to the question “When would be necessary to make use of the armored type cable?” is highly dependent on the application. There are many different kinds of electrical cables, but one of the most prevalent is called an armored cable. Armored cable varieties are well-known for the protective coating that surrounds their core and shields it from a variety of damaging situations, including excessive tension. The cable is useful for a broad variety of purposes, including the installation of subterranean wiring and the provision of electricity from the mains. Sadly, the majority of us are not aware that there are various different varieties of armored cable, therefore we typically opt for the type that is the most prevalent. The Steel Wire Armored (SWA) Cable is without a doubt the most well-known metal-clad cable in existence today. Nevertheless, it is not the only cable that possesses armoring. Before deciding on a specific type of armor cable to use for your planned application, you should first educate yourself about the meaning of the term "armor cable." Just like regular electrical lines, cables that include armoring can be used for a variety of applications. When selecting the improper type of armored cable, the end result is frequently a number of unfavorable effects, one of which is the need for repeated cable repair and replacement. This could end up being quite expensive in the long term. When searching for an electrical wire armored cable, there are a few things that are really necessary for you to be aware of. For instance, you need to have a comprehensive understanding of the many categorizations of wires that have armoring. Obtaining information of this critical nature can be quite tough, particularly for persons who have no prior experience in the field of power cables. You will be able to escape these unfavorable circumstances with the assistance of the five essential pieces of knowledge that are provided in this free post. Spend some time on it, read it carefully, and make sure you understand all that's important to know before moving on.
- What does the term "armored cable" mean?
An electrical cable is considered to be armored if it has an additional layer of protection built into it to prevent the inner components from being worn down by abrasion. Simply said, this cable type is sturdier than the standard electrical cables that are typically used, and it performs exceptionally well for its intended purpose. When working with this kind of wire, sadly, most people find that they are let down in some way. These sorts of disappointments are commonplace when the wrong type of cable is selected. The majority of people have the misconception that an armored cable can only be made out of steel. Any choice that is made on the basis of this assumption is frequently the incorrect choice. There are three main categories for cables that have to armor, and these are as follows: SWA Cable, which stands for steel wire armored cable The most well-known type of cable that have armoring is unquestionably one that is constructed using steel wire. The highly conductive copper conductor, the XLPE or PVC inner sheath, and the steel wire armor that makes up the outer sheath of this cable are the components that make up this cable. Because of its steel armoring, it is able to endure any mechanical extremes that could cause the cable to get damaged. As a consequence of this, the armored electrical cable is useful to have when dealing with applications involving the main power supply. The makers of armored cable produce this cable in two separate forms, namely low-voltage and high-voltage variants of the product respectively. The high-voltage variant can withstand voltages of up to 33 kV, while the low-voltage form can withstand voltages of up to 11 kV. It is strongly recommended that you base your decision on the cable that you want to use. In light of the fact that this cable is heavy and difficult to manipulate, you would be better off using it as a grounding armor cable. STA Cable, which stands for steel tape armored cable This armored cable is appropriate for wiring applications with a maximum current demand of 35kV or less. The outside sheath of the cable has a steel tape armoring that serves as part of the cable's structure. The fact that it is simpler to produce a STA cable than a SWA cable is the primary reason for the STA cable's lower price. However, it would not be good to prioritize the price of the armored cable over whether or not it is suitable for the purpose you have in mind. If you want to install some wiring in an area that is infected with rats and termites, this cable is an excellent choice. It is also widely used in the wiring installations associated with construction, underground mines, and applications relating to petrochemical industries. Before you commit to a particular armored wire, you need to make certain that the minimum bending radius of that wire is suitable for the application you have in mind. An armored electrical cable, regardless of its classification, shall not bend more than the minimum number of times recommended by its manufacturer for the bending radius. This minimal bending radius is often displayed somewhere on the outside sheath of the cable. Cable Encased in Aluminum Armor The fact that aluminum armored cable can only be used with single-core wires is one of the reasons it is not very common. Because of aluminum's non-magnetic characteristics, it makes an excellent choice for use as armoring in applications using a single core. Any attempt to apply steel armoring in a cable with only a single conductor would result in the cable overheating.
- When Is It Appropriate to Use Armor-Plated Cable?
An armored cable wire offers sufficient defense against the dangers posed by mechanical forces. Therefore, you can utilize this type of electrical wire in locations that have a high potential for being damaged by mechanical forces. To name just a few, these areas consist of things like outer walls, the subsurface, and industrial establishments. Strength and the capacity to withstand a variety of different kinds of external extremes are the characteristics that stand out most prominently in any armored cable wire. These kinds of conditions frequently involve being subjected to ultraviolet (UV) radiation, water, rat infestations, and different kinds of mechanical risks. In most cases, the usage of conduits is not necessary when using cables that have armoring. On the other hand, several regional codes mandate the utilization of pipes for any and all underground installations. As a consequence of this, before to carrying out any kind of subterranean installation, you should examine the wiring legislation in your area. You must be aware that there are numerous types of armored cables, each of which is designed for a unique purpose. For instance, the only use for an armored fire alarm wire is in the installation of an alarm wiring system. In a similar vein, an armored marine cable is particularly well-suited for use in contexts connected to maritime environments. To put it another way, you need to make a decision depending on the unique wiring requirements that you have.
- When Is the Use of Armored Cable Appropriate?
In the absence of conduits, armor-clad cables offer sufficient coverage in terms of protection and longevity. People are typically compelled to utilize conduits in locations that are vulnerable to external threats such as corrosion and cable abrasion; however, this is not always the case. Therefore, it is accurate to state that an armored cable is ideal for usage in locations where there is a high risk of hazards. The locations that are most likely to cause irreversible damage to a conventional electrical cable are those that are exposed to dampness. Because it is resistant to the effects of moisture, a wire that has been coated in metal is an excellent choice for this kind of setting. In dangerous areas, such as beneath stairwells, barns, and basements, to name a few examples, it is generally recommended to utilize armor-clad cables rather than traditional cables. If you select the appropriate type of cable, these cables can offer the highest possible level of both safety and longevity. An XLPE armored cable is your best bet when working with high voltage, so look into getting one of them. It is also very important to keep in mind that the amount of current that cables are capable of carrying varies based on a variety of parameters, such as the size of the wire, the number of cores it contains, and the length of the wire. For instance, a 6-millimeter three-core armored cable with XLPE insulation is capable of transmitting up to one thousand volts. It is not possible to say the same thing about the various other types of armor-glad electrical lines. WHAT MAKES METAL-CLAD AND ARMORED CABLES DIFFERENT FROM EACH OTHER? The primary distinction between an AC wire and an MC wire is that the metal-clad cable possesses a standard ground wire, whereas an AC cable relies on a jacket in conjunction with a wire or thin strip to secure the grounding. The grounding of an AC cable is accomplished by a combination of these two components. In conjunction with the bonding wire, the metal armor can also perform the function of contributing to the earth. The armor is not a functional component of the grounding in type MC wires. The fact that AC electrical cables are only used indoors and are not designed to be used in wet or damp environments is another distinction between MC and AC electrical cables. The fact that AC cables do not come with PVC jackets is the explanation for this situation. The use of a PVC jacket confers weather resistance on MC electrical cables, making them acceptable for installation in outdoor settings. AC cables, in contrast to MC cables, are not designed to be buried directly. Before MC cables were available, AC cables were the most common type of armored cable sold, and this was long before MC cables appeared on the market. They made their first appearance in the National Electric Code in 1903 when it was first published. MC cables, on the other hand, are an alternative that is more flexible and up-to-date nowadays. AC Cable has you covered if you require an armored cable for use inside your home. In that case, you should choose a cable that has a metal sheath.
