What Are Electric Cables? These electrical cables are mainly made of metals. These metals include copper, silver, and aluminum. As silver is scarce and more expensive, most cables are made using copper and aluminum. They mostly provide the same effect and service but can differ at certain times. There are three main components of an electric cable. They are conductor, dielectric, and sheath. The dielectric is used for insulation and this survives the high service voltage and isolates and separates the conductor from the other objects. The sheath is used as a covering and a protective layer, producing a buffer between the outside and inside.
Top 3 Types of Cables
If we talk about the types of cables, then, there are many, but if we focus on the best types, we will find three main types.
- Firstly, comes the single conductor cables. Single conductor cables are of two varieties. One is the standard cable. This is used in chargers, mainly the ones for. The reason behind this is because these cables are flexible, so they can be bent and stretched, to provide more comfortable and easier charging. The rigid single conductor cables are used when the wires are expected to be lengthy and even. So, yes, they are used in the overhead cables we see attached with the transformers. These cables transmit and conduct electricity better and more efficiently, so this is why they are used in these cases. The most common single conductor cables are the thermoplastic high water-resistant nylon coated cable (THWNCC) and the thermoplastic high heat resistant nylon coated cable, also known as (THHNCC).
- Multiconductor cables are a type of standard cables or wires, but each of the cables has at least two (or many more in some cases) individual conductors, inside of a common and same jacket. They are used to connect appliances that need high power input to work, mainly heavy appliances like washing machines, dishwashers, refrigerators, etc. Multiconductor cables are non-metallic, and they consist of a live wire, which carries the current, a ground wire, well known for providing a path to a safe place for the extra electrical charges. Lastly, there is a neutral wire, which makes sure all of the electricity is fully used, none of it is wasted. it does so by connecting the circuit back to the original power source. All of these are enclosed in a cover of a protective plastic sheath. As plastic is a great insulator, this layer makes sure there is no heat or electricity loss, simultaneously, protecting from electric shock.
- Metal clad cables are the last on the list. They are encased in a spiral metal casing, and this case is usually made of aluminum. Just like the other cables, they consist of a life, ground, and a neutral wire. These clad cables are used in industrial applications. This is because the cables are built in a way where they can withstand heavy loads. As the name suggests, there is metal involved in the manufacture and yes, metal is used for the casing material. This case is protective and is well known for providing protection, making sure the wires do not fail. They also reduce the risks of fire or spark, resulting in safer use. The cons side of these metal-clad cables is filled by them being a bit more expensive than the rest. As they ensure safer usage and are well known for carrying heavy doses of voltage, simultaneously preventing loss of energy, it is one of the topmost electrical cables, and needless to say. You will have to pay a bit more if you want all of these facilities.
WALTON makes sure the insulation or dielectric is strong enough to bear the service voltage and does not reach the conductor. Simultaneously, the sheath does not let any moisture enter and all the cables are saved from chemical attacks and fire.
WALTON confirms all the materials are of the best quality. They use impregnated paper, butyl rubber, polyvinyl chloride cable, polyethylene, and Cross-linked polyethylene for insulation.
The inner sheath is strong for bearing the inner pressure and is made of lead.
For the protective layer, they use paper and hessian to avoid damage by corrosion and electrolyte. The serving is waterproof.
The last layer that provides mechanical strength is made from thermosetting or some sort of thermoplastic material. This restricts water, corrosive materials, dust, and dirt from going inside.
The pricing of cables starts from BDT 500 on average and can lead to a couple of thousands. This pricing usually depends on the type of cables, and the features they produce. The safer they are, the more they cost. How much time it takes to assemble them and how much involvement is required is also a deciding factor.
How to Take Care?
Wires are known for lasting 10 t0 20 years, on average. But it is seen that sometimes they break earlier than usual, and this same thing keeps repeating. So where exactly are you going wrong? To make sure the wires you buy last longer and give the value for your money, you need to resist bending your cables excessively. Alongside, you also need to stop wrapping them in bundles too tightly. Doing either of these will cut down the longevity of your cables as when you do these, the resistance increases in your wire, the current takes more time to pass, making the cables heat up. As a result of all these the cables wear out sooner than usual.
While buying the cables, first and foremost, you should check for the cable construction. Make sure they have a good conductor, along with the other important cable components. Then, you should see the cable installation and the distribution features. You need to make sure whether the cables you are buying can withstand the load you want them to bear because if not, it will be a total wastage of money. The most important thing is the insulation and the finish covering as they act as the protective layer of cable. There are certain percentages labeling on the cable that will help you have a clearer idea about the insulation.
All of the mentioned factors are found in WALTON cables and their suggestions and service will lead you to your desired cable.
