Acquaintance with the structure of the power cable
Before buying a standard electric wire and cable, it is better to be familiar with the important parts of its structure:
Conductor: Conductors are the only power transmission path in electric cables and are made of various materials such as copper (ATC and ABC) and aluminum.
Insulation: Insulation, which is usually made of PVC, XLPE and various types of rubber, is placed on each cable conductor. The material used for insulation is selected based on the desired operating temperature.
Inner layer: This part of the cable, also known as the inner sheath, is mostly used in multi-core cables.
Armor: Armor protects the lower interconnected parts of the cable. Armor is usually made of steel.
Outer Sheath: The outer sheath or jacket is the final layer of the cable and is usually made of PVC or CSP.
What are the features of a good wire and cable?
Cable:
Of all the cheap metals, copper is the best conductor of electricity. The most important factors that must be considered to determine the conductivity of electrical wires and cables are resistance, cable size, and insulation materials.
If you intend to buy cheap and lighter wire and cable than copper, aluminum will be a suitable option. But since this metal has only 61% conductivity of copper, it is not the best choice in this field.
Wire resistance:
Choosing an electric cable with good quality and high strength is very important. You must be sure that the purchased wire is resistant to all environmental factors, including air temperature, and maintains its performance.
Coating and Insulation:
The covering of electrical wires is used to protect the cables against any physical damage. Insulators are usually made of steel strips and by increasing the strength of the cable, they make it safe from any damage. By buying high-quality Amol wire and suitable insulation, you will not need to buy and repair the cable again.
Resistance to water and fire:
Poor wiring can damage or disable electrical appliances or industrial machinery. Such cases may lead to consequences such as electric shock or fire accidents.
To avoid such problems, you should buy wires with proper thermal stability that can withstand high operating temperatures. Many cables with PVC insulation are resistant to environmental factors. Using high-quality wires and cables plays an important role in preventing voltage fluctuations and short circuits.
Energy durability and productivity:
One of the most important features that you should consider when buying electric wire and cable is its durability. Typically, high-quality copper wires used in the construction industry are highly resistant to problems such as rusting.
Using high-quality and durable wires will increase energy efficiency and help you reduce your electricity costs to a great extent.
How to detect the quality of the wire and cable?
Product Packaging:
When purchasing, make sure that the packaging is clearly printed and clearly shows the model specifications, supplier name, factory address and other such information.
The appearance of the wire:
Pay attention to the appearance of the product and make sure it is smooth and uniform in color. If the wire and cable is rubber, you can burn the insulation with a cigarette butt without damaging the surface.
Conductor Wire:
eThe wire conductor has a certain brightness and is relatively flexible. Pay attention to the cross section of the wire and cable core. Copper wires are light in color. If it is other than this, the product is defective.
Cable length:
When buying a cable, don't be tempted to buy a cheap 80 or 90 meter cable. The minimum standard cable length is 100 meters.

PVC coating:
The surface of a good and standard cable has a net texture, compact and uneven. If the appearance of the wire is smooth, it will slip when working.
