The main component of an electric power cable is its core. The conductor is the element that carries power from one point to another. This is why it is made of a highly conductible material. In most cases it is copper or aluminium. One of the longest ranging debates in the field is about copper Vs aluminium — which one works best!
Copper was the conductor used in the first power distribution system that was developed by Thomas Edison for the New York City. It was the favoured metal for almost all first experiments with electricity, such as telephone and telegraph. This is because it is one of the most conductible metals, second only to silver.
In fact, the conductivity of copper has increased as processing technology has given us a purer metal. In 1913, the International Annealed Copper Standard was adopted to compare copper’s conductivity against other metals.
Although aluminium joined the party a bit late, it soon became the conductor of choice because of its properties. The aluminium used as conductor in most electric power cables today is actually an alloy of aluminium. In fact, the alloy AA-8000 was actually developed to mirror some of the advantages of copper.
Now let us do a comparison of both conductors:
Conductivity: There is no doubt that copper has better conductivity than aluminium. In fact, aluminium has just 61%conductivity of copper. This makes copper a more efficient carrier of electricity.
Weight: Although aluminium has less conductivity than copper, it more than makes up for this in weight. In the end, we compensate for copper’s conductivity by simply increasing the weight and bringing it at par with copper. For half the weight we can get the same resistance.
Price: Another advantage of aluminium in electric power cables is its low cost. Aluminium is one of the most commonly found elements, where the occurrence of copper is not as abundant. With better technology copper prices have also fallen and we do see some designers switching back to copper. However, copper prices, because of their limited availability, often fluctuate wildly. This makes it unsuitable for long-term projects.
Properties: Copper alloys can usually give one 20-40% elongation. Aluminium, on the other hand, only gives us 18% elongation. However, some aluminium alloys, developed to increase elongation, do better. AA-8000, used in power circuits was developed to copy the properties of copper.
Diameter size: Because of its far higher ductility, we can get copper conductors with a smaller cross section. This property is further aided by copper’s lower susceptibility to problems arising out of electrical contact. This gives it multiple advantages. To begin with, we can have thinner cables that are easy to install.
The smaller cross-section of the copper means that copper wires are also less stiff, which further aids their installation. With copper we can also get very fine starred cables. While we can also achieve fine stranding in aluminium, it is never quite as fine-stranded as copper. The individual wires are also thinner in the case of copper. This is why the ‘extra fine stranded’ cables always contain copper conductor.
Cost of installation: In this case, both copper and aluminium have their advantages. Where weight is a consideration, as in the case of shipping, aluminium wins because of its lighter weight. Lighter aluminium core cables do not require heavy supports in elaborate projects like power grids. But where weight is not an issue, copper cables are often easier to install because these are more flexible.
Durability: Copper has better resistance to corrosion than aluminium. It is also better at handling stress. Aluminium also cracks when it is subjected to vibrations. This is a problem in power cables where electricity often makes the cables vibrate. Vibration is also a concern in motors and transformers.
Recently, a combination of copper aluminum has emerged as a viable solution. The electric power cables carrying both aluminium and copper wires combine the quality of both elements.
Electric power cables can have copper or aluminium conductors. While aluminium is cheaper and lighter, copper is more durable, flexible and has better ductility. It also has better conductivity than aluminium and is hence, used more frequently than aluminium.
It is probably a universal truth that we expect our belongings to be durable. Whenever we buy something, we generally look for traits of sturdiness which indicate durability. This expectation is not limited to personal or household items but also to commercial items that we might be buying for our business purposes.
Looking for qualities of robustness is one thing, and maintaining a product so that it remains in a good shape is another. A lot of times, a product disintegrates not because of its quality but because of maintenance or usage issues. A few simple tricks can help ensure longevity of many items. Today, we will discuss how to take care of wires and cables efficiently.
The Three “Ins”
All wires and cables manufacturers have a set of instructions on the things that you should avoid to ensure that the wires and cables do not get damaged. These instructions include conditions that these cannot withstand, inspection or maintenance timeframe, ideal usage, etc. The guidelines can really make a difference in how long your wires and cables remain intact.
Additionally, manufacturers’ warranty requires you to abide by the instructions because any damage caused due to your handling will not make the manufacturer liable. This just does not apply to wires and cables but to almost all products that have a warranty.
This is an extension of the instructions that we discussed above. Different types of wires and cables have different qualities. For example, some are meant for high voltages, some are resistant to weather, others might be extremely safe because of the insulation. These qualities make each type of wire and cable ideal for a purpose.
Wires and cables manufacturers have installation guidelines as well. Some wires and cables might not be safe if the connection is exposed, others might need no contact with moisture, etc. If the installation is not proper, the wires and cables will get damaged and cause a lot of hassle.
An inspection of all types of wiring prevents accidents and also ensures longevity of your cables. Sometimes, a small section of cable or wire may have cracks or signs of damage that can prove to be fatal. If you overlook such damages, there are chances of short circuits resulting in a longer fault and bigger damage.
Unlike other electrical equipment, inspection in this case cannot be a regular affair because of the nature of connections. Therefore, follow the wires and cables manufacturers’ advice in terms of after the timeframe that the wires and cables can withstand.
If you ponder, all of us have access to these instructions, installation and inspection guidelines. But, we generally do not pay heed to these and it results in deterioration of wires and cables. A fault can cost a lot of money both to replace the products and also to get the connections redone. The trouble caused as a result is a bonus. Therefore, abide by your manufacturers suggestions and enjoy worry free connections.
Faulty operation, electrocution, fire hazards are some of the hazards involved when cables are pinched and exposed. XLPE power cables suppliers will explain how an exposed and damaged power cable can be a threat for your laptop in this post.
Exposed and damaged laptop power cable can bring serious electrical problems with it. These include incorrect power flow or intermittent delivery of power. Incorrect power flow can result in spikes that can damage sensitive components installed inside the laptops, such as drives or chips.
The device may also deal with a lack of adequate power. Electrical spikes and inadequate power supply can make severe damage over time.
Excess power, whether supplied through spikes or poorly regulated power supply, results in heat damage. Heated cables and power cables will get damage and user will not be able to avail quality performance. There is a risk of combustion as heat builds in the device. When the excess heat reaches the flashpoint of nearby furniture or carpeting, it may blaze the materials. This may result in major fires that threaten the whole office and buildings.
Injury and death
You may get severe skin burns and even death by electrocution. Power cable manufacturers always advice not to handle damaged and exposed cables while they retrieve power from any source. Cables that are connected to a socket have the potential to give nasty burns by drawing power from the wall into the hands of the person who touches the cable.
A life can end with an electric shock. You may also get severe injury, such as involuntary muscle reactions, physical shock, muscle paralysis, and burns. Death by electrocution poses very real hazard for those who are handling exposed and damaged power cables for the laptops.
There are special bodies that have set strict guidelines related to use and operation of power cables, especially in sensitive areas, like hospitals, restaurants, etc. Code violation includes the use of improperly grounded power cables near water sources.
For more information on damages of power cables and its threats, you may contact XLPE power cables. They are supplying premium quality range of power cables and wires along with the guidelines for installation and usage. You must follow these guidelines properly to avoid hazards that may cause by mishandling or misuse of power cables.

The term “savings” is not introduced to the people just like that. Power cable manufacturers want that people should make judicial use of electricity and power cables. You can conserve energy by taking actions such as weatherstripping/insulating your home and buying high efficient appliances. These options are usually the smartest and most economical than you think. Greener, cleaner energy supply may offer the cleanest supplies of required energy, but lowering the energy we still need to take the first step prior selecting the greenest, cleanest supply.
You need to understand that when you save energy, you not only save money, but also reduce the demand for such fossil fuels like coal, natural gas and oil. Lesser burning of fossil fuels results in lower emissions of carbon dioxide, which is the primary contributor to global warming and other contaminants.
You can consider some of these energy-saving tips. Though, these tips won’t save your money instantly but in the long run. And you can measure their CO2 savings in tons every year.
The small investments you make actually makes a difference. When you buy more LED bulbs and replace your CFCs and halogen bulbs with them, your energy costs is saved by 95%. LED bulbs provide more light and consume little energy as compared to ordinary bulbs.
Always wrap your water heater in an insulating jacket. Use less hot water by installing low-flow shower heads. Switch off your lights and fans while leaving any room.
Bring quality power cables from prominent manufacturers. There are power cable manufacturers offering best quality wires and cable solutions for domestic and commercial purposes. You can bring such products and get a continue electricity supply without any disturbance. Using worn cables will lead to mishaps. Always replace the old wires and cables with new ones when you notice wear.
When you read about the manufacturing of any power cable, you may found that there are distinct types of cables and wires manufactured by the companies. In this article, PVC cables manufacturers will share all technical aspects of PVC Cables i.e. their manufacturing process and major advantages in brief. Let’s read them.
Manufacturing process :
Copper conductor wire of the required size is inserted into the extruder. In the extruder, PVC is coated on the wire to a specific thickness. The extruded wire is coiled on the take off system after passing through the cooling tank. Manufacturers coil the wire into the length of 100m and test their products as per IS specifications.
PVC cables are available as thermoplastic dielectric. Manufacturers use PVC compounds for such cables that take great care of over load and short circuit currents with both fine and coarse protection systems.
Laying up - Cores are tested by the team online during manufacturing process for electric and physical attributes. For multi core cables, cores are laid up on laying machine, which are already equipped with sector correction equipments.
Insulation – The cables after laying up process are offered with insulation of premium quality of PVC polymer, which is softer than the outer sheath and are compatible with cables temperature rating.
Outer sheath – Cables are offered with polymer or pvc sheathing with several sheathing compounds characteristics.
What are the advantages of PVC cables?
There are lots of advantages offered by PVC material based cables. Let’s discuss them –
There are many tests performed by PVC Cable Manufacturers to check conductor resistance, thickness of thermoplastic and elastomeric insulation and sheath, shrinkage, ozone resistance, cold impact, heat shock, bleeding and brimming, etc.
You can find more details online. On internet, there are several articles published by experts. You can read them and avail more info on PVC cables.
Welding cable is usually classified as a type of industrial power cable. It’s much more flexible than THHN wire or any type of electrical wire. There are two types of flexible welding that I’ll tell you about and a few other types of single conductor flexible cables that are very similar.
Welding cables is commonly defined as one of the most popular industrial cable that is always more flexible when compared to other types of similar wires. Welding cables can either be insulated with rubber material or you can use PVC insulation too. Rubber insulated pipes are always more flexible when compared to PVC insulated wires.
The next important design consideration is copper strands that make industrial power cables even more flexible and good in strength. The wires with maximum insulation characteristics can be easily installed with industries even with rough surfaces. They are designed in different colors and dimensions as needed by clients or different industries. There are many power cable exporters and manufacturers in India that offer custom solutions for different projects to assure best outcomes.
Another popular invention by power cable manufacturers and exporters is DLO cables i.e. Diesel locomotive cables with added insulation or thickness to give extra protection to equipments. They are not as much flexible as DLO cables but much bigger and more powerful in nature. DLO cables may also run above ground and raceways when necessary.
Both DLO cables and welding cables are made rugged to use with harsh conditions as required by industries. You have to be extra careful when deciding on any type of industrial power cables. It could dramatically manage your budget and efficient too depends on cable used inside. You have to make sure that you are getting only affordable deals only from leading Power Cable manufacturers and exporters in India.
The feeling of building a new house is always satisfactory and sometimes overwhelming too. But deciding on where to fix your electronic device is always critical and challenging that cannot be dealt easily.
Here, we are discussing on some of the important facts that are necessary to focus on along the way and should be practiced carefully.
The focus of installing lights in your home is not just about where you wish to use it but how to control it. Dim lights that need smaller voltages always put an extra strain on usage of power resources to check how to avoid electrical issues and other related problems.
In this way, spending time in checking on electrical checklist for your home not only reduces requirement of extra cables and boxes but maintains your home in best way.
Electricity is the utmost essential element in the world since almost a century now. Electricity has become a part and parcel of everyone's life and so are the devices that work with it.
The most important part of electric power transmission are the electric power cables which facilitate appropriate distribution of power from the systems to varied appliances that we use.
Although most of us know what electric power cables are and how they transmit power when connected to devices, it is definitely also important to understand how they work and what they comprise of to perform the best, so as to remain safe and also attempt to analyze faults at any given time.
Electric Power Cables comprise of a bunch of electric wires or optical fibers technically wrapped in a sheath. Power cables are built according to the task they are intended to perform. For instance, the environmental conditions where they would be placed, voltage of power that would be passed through them and the capacity of current that they can carry; based on these aspects, a power cable's material is chosen and the product is designed and constructed.
Sometimes when power cables are to be used in very harsh environmental conditions, the power cables are made with durable materials like steel or aluminum respectively.
An electric power cable comprises of the following components and they are:
Now let's look into the major advantages of using electric power cables:
Alongside these exceptional features, power cables also come in a spectrum of varieties:
Electric power cables in India are manufactured and exported by various firms that have certain specifications for maintaining superior quality and they actually follow quality-assurance protocols so as to deliver excellent products to the local industries and to those located in other nations.
In the recent years, the power cables industry has taken giant strides creating better business prospects for manufacturers and exporters who could leave a good remark in the international power cable market.
