Construction Of Power Cables

by Sagar Chauhan Digital Marketing Analyst

The power cables are designed to transmit or distribute electricity or electric power. The design of these cables is made as per the requirements of power distribution and power transmission. One or more insulated electrical conductors are assembled together in a sheath to form the power cables. The electricity is transmitted by the use of these wires in the power cables. Most power cables are installed in various buildings as permanent wirings. The wiring is done inside the walls or the ground. However, the wiring at some places could also be done in the open space. Most manufacturers of the power cables strive to incorporate flexibility into it. These can be used for varied applications like mobile tools, portable devices, and different types of machines. The buyers of the power cables also specify their requirements to the manufacturers for getting the design of their choice. Want to know the details of the construction of the power cables? Well, keep reading ahead!

Construction Of Power Cables
The power cables that are installed underground or inside the walls have several advantages. They are safe from any kind of external damage like storms, low maintenance, heavy lightening, and other such issues. Moreover, there is a less chance of the occurrence of any faults or drop of voltage or bad appearance when the wires are installed inside the walls or underground. Moreover, the power cables are rated as per the short circuit and voltage drop before they are allowed for sale in the market. The basic construction of the power cables by using various parts is mentioned below:

·    Conductor: The conductor comprises the power that is carried or transmitted in the power cable. Manufacturers prefer using the conductors that are made of aluminum or ATC/ ABC copper material. The conductor size is decided as per the resistance of the conductor.

·    Insulation: The cable conductor needs insulation. This is done by using different types of rubber, poly vinyl chloride or PVC, and cross-linked polyethylene or XLPE. For selecting the insulation material, the operating temperature is taken into consideration. Also, manufacturers use different colors or print the numbers on the insulation for identifying the cores.

·    Beading: The beading could also be called the Inner Sheath. This sheath binds all the insulated conductors together for forming the multi core cables. The beading is usually made of the PVC material or rubber material.

·    Armouring: Two types of armouring can be done: G.I. steel strip and G.I. wire armouring. These strips or wires are placed on the sheath present inside the cable. This process helps in creating the earthing shield for the cables that have current inside them. It is also used for safety.

·    Beading: The second type of beading is known as Outer Sheath. To give excellent mechanical protection and earthing for the cable, the process of beading is used.

·    Outer Sheath: The final process is to create the outer sheath of the cable by using the PVC material or rubber. It protects the wire from chemicals, weather, and any other mechanical issue.

Now that you know the construction of the power cables and the materials that are used in this, you should be able to select a reliable power cable manufacturer in India or any other country.
