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.

Different types of Cables and its uses

According to the nature of applications different types of cables can be used in domestic, commercial and industrial set ups. Cables are categorized in number of parts first is single conductor cables and other is multi conductor cables. Lets we discuss about these cables and their features that are helpful f
Aluminum Cables: These cables are the types of electrical cables that are mainly used for high power applications. These types of cables are famous for their high conductivity. The Aluminum cables contain the features of light weight, non-magnetic and ductile. It also contains silver-white metal that are reflective to heat and can be recycled also. These types of cables mostly used for those applications like motors, electric lights, Telephone lines etc.
Copper Cables: Copper cable mainly used electrical cables that are widely used for industrial segments and the important elements are mining, electronics, telecommunication, transportation. Telecommunication sectors mainly used these cables just because of their light weight, ductile and flexible nature. You can find Copper Cables in integrated circuits, electrical bus bars, electromagnets, microwave ovens and electrical switches.
Industrial Cables: These cables are specifically designed to oppose severe temperature and find application in those areas like oil refineries, aviation, chemical plants, pharmaceutical companies etc. The industrial cables are highly resistant to oil, grease, chemicals and flames, etc. Some types of industrial cables include coaxial cables,armored instrumentation cablescontrol cables and many other industrial power cables.
Fiber Optical Cables: Fiber optic cables are made of one or more transparent fibers which are cover with a protective jacket. These cables are categorized in three parts as Simplex Fiber Optical Cables, Duplex and Multi-Fiber Optical Cables. Simplex fiber optical cables have one optical fiber, Duplex fiber optical cables have two optical fibers and the multi fiber optical cables have several optical fibers. These cables are mainly used in telecommunication and computer network.

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.

What Are The Criteria For Selecting A Quality Power Cables

These days, power conception by general public and various industries are increasing day by day. To meet the Growing requirements of quality power distribution for industrial and residential use, electricity distribution systems are hurriedly undergoing upgrades. Looking to safety measures and quality of services, converting the overhead line to high quality underground(UG) cables in low tension and high tension electricity distribution networks. power cables are the major component of new generation Power distribution system. Technical requirements for power and control cables are:
a) Armoured copper/ aluminium power and control cables: Extruded PVC sheath inner , single round galvanised steel wire armoured and provided with PVC sheath outer. Both outer and inner sheaths shall be ST-1 as per IS: 5831.
b) Unarmoured copper/aluminium power and control cables: extruded PVC sheath inner and provided with PVC sheath outer. Both outer and inner sheaths shall be Type ST-1 as per IS: 5831.
Insulation for cables. XLPE insulation for cables have a higher current carrying capacity, light weight and short circuit rating 250°C as against 160°C for PVC. An excellent electric properties of XLPE are high dielectric strength and very low dielectric losses. Due to water tree growth in XLPE, specially designed insulation materials called WTR-XLPE. WTR-XLPE insulation materials lead to a much longer in-service life for power cables. Inner sheath and outer sheath insulation shall be applied by separate extrusion. Insulation should not be damaged when exposed to the bad weather conditions. There are some of the important factors should consider when buying power cables:
(a) About Manufacturer
(b) Voltage grade
(c) Successive length
(d) Size of cable
(e) International standard Mark
(f) Year of manufacture
Quality cables have high tensile strength and perfect resistance to high temperatures. WTR-XLPE cables work in both moist and dry conditions. Cross linked polyethylene cables have distinct advantages such as lighter weight, better electrical and thermal properties, less maintenance, and easier terminating and jointing procedure etc. Always choose to buy a power cables from International standard system certified cable manufactures. Choosing electric cable for power distribution and house wiring is very difficult. All the cable manufacturing companies and suppliers convince their substandard product to buy. Before selecting the brand, always cross check the quality of the product and its manufacturer's system standard certification. Quality product can only deliver 100% safety with satisfaction. Always cross check about product quality, and its manufactures to buy a cost effective, long reliable service life power cables.
