Of all the types of electrical wires around, these are the ones most commonly used.
Most coaxial cables have a copper core, which is a solid wire that carries the electrical signal. The core is insulated with a layer of plastic called the dielectric, which separates the core from the cable's outer layers. Coaxial is mainly used for TV and internet because it can carry a lot of information over long distances without losing much signal. It is also pretty immune to interference, making it perfect for use in places like homes and businesses where other electronic stuff might mess with the signal.
Fiber-optic cables are way better than coaxial cables when it comes to speed and distance. They are made of glass or plastic strands that are way smaller than a human hair. Info travels through light, which is super fast. Fiber optic is used for the internet, telephone lines, and even TV because it can carry loads of information in a blink without losing any signal over long distances. Plus, it doesn't get messed up by electrical interference like coaxial can.
There are a ton of different types of electrical wires. But the most commonly used ones are copper and aluminum. Copper is the go-to choice for wire because it conducts electricity like a boss. It is super flexible too, so it's easy to work with. Aluminum is cheaper and lighter, so it is also popular.
Even as inflation affects the Indian economy, the cost of wires keeps changing for these reasons.
The materials used to make the cables have a lot to do with their prices. Most electrical cables are copper or aluminum. The price of copper will affect how much the wire costs, too, since the cable maker has to pay that much. Even though aluminum is cheaper, it is still costly compared to other materials.
Cables have an insulating layer to protect them from getting short-circuited. In addition, this layer is made from plastics like PVC. Depending on what kind of insulation is needed, the cost may be higher or lower. For example, HDPE insulation is more durable, but the price goes up.
The larger and more complex the cable, the higher the price. Any B2B buyer who wants multi-core cables or those with different insulation types will pay more than for simpler cables. Also, long wires will cost more since it takes more material to make them.
PVC insulation is made from polyvinyl chloride, a very common and handy plastic that makes wires last longer. It is also super cheap, which is why people use it all the time. It is flexible but still hard enough to handle tough jobs. That is why it is still a great choice for making electrical wires indoors or in places where wires do not get really hot.
XLPE insulation is made from cross-linked polyethylene, which is hotter and tougher - literally. The process "cross-links" the plastic molecules to make the insulation more durable and stick around even when it gets really hot. However, this is a more expensive option than PVC.
Many cables are imported, so the price of rupees to dollars or any other currency will affect how much the cables cost here.
India has a plethora of electrical wires, so the following factors must be considered when selecting one.
The coil or core of the cable is very important because it conducts electricity. A thicker coil can carry more current. A thin coil works for light and low machines. Large industries need thick coils to power machines. As for coiling, multi-strand coils provide more flexibility and durability. Single strand cables have higher conductivity and are, therefore, used in fixed installations. Where and how much flexibility is required should be considered before selection.
What insulates the wire determines where the cable can be used. PVC insulation is the go-to because it is affordable and super versatile. It works for most home and office uses. But for really high temperatures or special jobs, XLPE insulation is better, even if it costs more. Do not forget the copper conductor because it is the best insulator.
Some cables, like the armored ones, have extra layers to safeguard them from physical damage. If the wire will be in an area where machines or animals could cause harm, go for armored protection. The armoring material could be steel wire, tape, or strips, depending on the level of defense required.
Cables are used for different purposes. Some are for homes, some for industries. Cables for homes do not cost much but help power a house on normal voltage and current. Wires that carry power over long distances, such as transmission lines, are built for safety, conductivity, and durability. Wires used in manufacturing or heavy machinery need to handle extreme temperatures, mechanical stress, and heavier loads.
The working environment determines what kind of wiring is needed. Cables for outdoor use are built to stand up to the weather. Those for underground installation resist water and chemicals. Marine-grade cables can withstand salt, water, and extreme weather. The ones in hot areas use heat-resistant insulation.
In India, the Bureau of Indian Standards and the International Electro technical Commission set general quality rules. These agencies assign letters for different types of wires based on their unique qualities. Select cables that have the right letters and approvals depending on where and how they will be used.
Taking care of electrical wires helps prevent damage and lowers the risk of fires or other accidents. Here are some things that can be done.
Do not let heavy things fall on the cables. Also, inspect wires tied around many places for strain or stretching. With time, these cables worn down, so replace them as well.
At least give the cables a simple once-over every few months. Check for bare wire showing through the insulation, any fraying, or major cracks. Catching things early makes fixing them easier.
Do not use electrical wires for things they are not meant for, like using extension cords with power tools inside or running cords from one room to another through doors or windows. This puts a lot of stress on the cables. Limit the usage of cords and extensions and run wires in open and safe areas only to maximize their durability.
Keep an eye on how hot wires feel to the touch while in use. If one gets extremely hot, this is a bad sign. Turn off connected devices and let it cool down to check later. Call a pro if any wire overheats - it could be a fire risk.
Any wires that have major visible damage, like exposed copper, deep cuts, or burn marks, need an expert to assess them. Do not delay calling in a pro for seriously damaged wires - it could be dangerous. DIY fixes on badly worn or damaged wires are risky. Professional repairs will ensure safe long-term use.
Follow these guidelines to keep wires in good shape.
A1: Using high-grade insulation and regularly inspecting the wires for damage helps avoid wiring deterioration.
A2: No, these wires are insulated with regular PVC and cannot endure extreme conditions. One should use XLPE insulated wires for heavy dust, heat, or humidity.
A3: Copper wires have more tensile strength and electrical conductivity than aluminum. This makes them ideal for heavy industries. However, aluminum wires are more cost-effective and lighter than copper.
A4: Buyers should choose cables with additional protection like armored wires. They safeguard the cable from intense pressure or heat.
A5: Multi-strand copper cables are great for domestic use because they are flexible and can carry a lot of current.
