Armoured Cable Ensuring Electrical Protection

Electricity has become one of the most important parts of our lives. In fact, we cannot imagine a day without electricity. From the moment we switch on our geysers in the bathroom to the moment we switch off the lights before retiring to bed, electricity has become one of the most indispensable inventions of our time. When setting up a home, it is important to see that all the electrical wires and cables are installed in a safe way. Many a time, short circuits or blown fuses can lead to a large conflagration. It is thus, important to always use very good quality cables and electric wires.

With the advancement of technology, people have started using much safer equipment. There are now different types of cables based on the amount of protection it provides. For instance, Armoured Cable is one type of cable used nowadays which provides a great deal of protection from short circuits or any such electrical problems.

If you are planning to install electric wires and cables yourself, a very safe bet would be to use the Armoured Cable. Though they are generally used to carry bigger amount of electricity and fall under the category of power cables, there are many do it yourself videos which will give you step by step instructions to install these cables for your use.

There are different categories of Armoured cables available for added security- for instance the Steel Wired Armoured Cable is another variation where the wire used inside the cables is specifically made up of steel unlike copper or nickel like the others. The main advantage of having a cable made of this material is that the conductivity of such cables will be a lot more than the conventional Armoured Electric Cable. But at the same time, if you are planning to use it on a large scale level, then it would be best to use a normal one. These are a tad bit expensive than the traditional cables and if you are not planning to spend too much on your wiring then, it is best advisable not to go for it.

Cables are generally safer than installing normal wires because of the protective sheath around them. The sheathing provides insulation against any kind of electrical short circuiting. These are available at most of the electrical hardware stores and the shops. One best way to ensure that you get these at an affordable price is to make your purchase from the wholesale electrical shops. They give you such material at a price which is much lesser than the ones obtained in the conventional stores. Always check for the warranty of these products before making the final purchase. Buy from credible stores only.

What is Armored Cable?

Whenever the question of building wiring is raised, one comes across the term 'Armoured Cables'. After all, what is armored cable and why is it so important for electrical wiring systems. It's mainly include Steel /Aluminum wire armored cable and Steel/Aluminum tape armored cable. Let's know about it.

Armored Cable Definition

Armored cable is a power cable made up by assembling two or more electrical conductors, generally held together with an overall sheath. This electrical cable with high protective covering is used for transmission of electrical power, especially for underground wiring needs. However, these cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or may even be kept exposed. They are available as single conductor cable as well as multi-conductor cables.

To be more precise, armored cables can be explained as electrical cables with stainless steel or galvanized wire wound over the conductors and insulation. They often have an outer plastics sheath for main distribution supply and buried feeders.

Why is Armored Cable Significant?

As can be made out from its name itself, armored cable is significant due to the ultimate protection it provides keeping in view the most risky job of electricity transmission. It acts as a circuit protective conductor (CPC) and thus provides earthing to the equipment supplied by the cable. However, its earthing capability has been a much debated subject.

Armoured Cable Earthing

A single conductor armoured cable does not have a ground wire. Its sheath is only for protection purpose. Therefore it is always recommended that one core armor cable should not be earthed on both ends. When both the ends are grounded, a "circulating sheath current" can flow between the armour, to ground then back to the armour. Grounding only one end is meant to allow bleeding of any voltage that might be induced into the sheath without creating a circulating current.

Single core armoured cables do not have magnetic fields generated by the other two phases. In a three phase cable, the sum value of the three magnetic fields is zero. In a single core cable, there is no "cancelling" effect and therefore a voltage will be induced in the armour by the magnetic field surrounding the conductor.

To prevent any kind of problem, a single conductor metallic armoured cable having lead, aluminum, stainless steel, steel or copper armors should be bonded to ground, usually at the source end, then isolated from ground along its length.

Know about Electrical Wires and Underground Cables

One of the most significant parts of modern living is electricity. Entertainment activities and other things depend on electricity and applications running through it. Optimal conditions of electrical wires are essential for smooth running for electric systems. Two things are important when deciding what type of electrical wires should be used at home. One is size of the electrical wire and other is the safety issue regarding wiring conditions. Wire gauge system determines the size of the electrical wire. The amapcity increases if the wire gauge is smaller and vice versa. Amapcity is defined as the safe amount of current that does not make the wire hot enough to catch on fire. Safe plastic covered electrical wires, called NMC (non metallic sheathed cable), are ideal for indoor wiring. Many types of these non metallic cables are available. Popular wires include NM, NMC and UF electrical wires. Nm electrical cables are usually used for indoor wiring such as receptacle circuits and lighting.

NMC electrical cables, being well insulated and safe are used in damp areas or above ground. UF (the underground feeder) can be used outdoor in the ground. These cables are not safe to use above the ground because cable sheathing can be destroyed by sunlight.

Copper electrical wire, aluminum electrical wire, alloys and silver are the electrical cables which are different in performance and price. Copper wire is considered gold standard and most homes rely on it. Aluminum is cheaper than copper and can easily be shaped and bent, but is less conductive. An alloy is made from aluminum and copper to get the characteristic of both and is used in industries.

An underground cable is a type of electric power cable, which is installed in underground ducts. It is mostly used in cities where shortage of space and safety concerns prevent the use of overhead lines. Now, installing underground cable has become an easy task because many topnotch types of equipment are available for professionals to install. Cable winches, cable ploughs, cable trailers and electric blowers are the equipment used by professionals to install these underground cables. A professional CLP company must have a good collection of cable winches. Its main function is to drag the cable at uniform speed. Many different configurations of cable winches are available. They range from light weight to much larger, more elaborate equipment. Cable ploughs are also an extremely vital equipment, to dig the drenches to bury cable quickly. Cable trailers are used to transport cables in a smoother way. Electrical blowers are more efficient. Air is blown down a propelling cable at uniform speed with the help of these electric blowers. Underground cabling equipment is vital to install underground cables efficiently.

All About Armored Electric Cable

Armored cable is a power cable usually made by assembling two or more conductors held together by a sheath. Such a cable comes with high protective covering and is used for transmitting electric power. These cables may be installed as permanent wiring within building or buried under ground.

To be precise, armored cables can be recognized as electric cables with stainless steel or galvanized wire wound with a conductor and insulator. They have an outer sheath for distribution supply.

Significance of Armored Cables

Armored cables are apt for high voltage electrical transmission applications. These include a circuit protective conductor within that provides earthing to the cables. Single conductor Armored cables do not come with ground wiring. The sheath is for protection purposes only. Therefore when it comes to earthing, it is recommended that one core cable should never be earthed on both ends. To prevent an electric leak, a single conductor Armored cable having lead, aluminum, stainless steel, or copper armor should not be laid on ground.

Advantage Of Armored Cable

Armored cables are extremely flexible and this makes them the right choice for industrial purposes. The mechanism involved in these cables allows more flexibility and durability. The chromium content in the steel armor protects the cable from damage even in the harshest of environments. Armored cables can also withstand considerable levels of heat due to the presence of PVC bedding. The external protection in conductors allows better transmission of electricity, even under high pressure.

Purchasing an Armored Cable

If you are purchasing steel wire armored cable for strength and durability, then you must keep the following points in mind.
Color of cable for coding: Steel wire Armored cable comes in colors such as white, blue, black, red, etc. Black, red or blue colored wires indicate live wire. White is neutral, green is for earthing.

Materials for making a wire: The most common material used for making an Armored cable is copper and aluminum. Thus, choosing the most suitable conductor requires proper product knowledge.
