Today i will discuss the cable classification and specification of electrical cable so let s go.
Different types of electrical cables and their specifications pdf.
Different types of electrical cables each have their own specific purposes and applications.
It is also called conductor.
These markings provide important information about the wiring and insulation including the wire size and material the type of insulation the number of wires contained inside a cable and any special ratings or characteristics of the wire.
Nm b cable nm stands for non metallic which refers to the flexible typically pvc sheathing surrounding the cable.
First of all i want to tell you why you need to know about the electrical cable classification and specification ok let s consider you are an electrical engineer or a technician and it means you are on work.
Conductors are the only power carrying path in a power cable.
Single cable from time to time this name is used for wire submersible cable.
Within a metal control cabinet to foil or braid shielded cable for areas of high emi or electrical interference.

Various degrees of screening are used according to the cable type and application.
Conductors are of different materials.
Cable is an important object in the electricity.
Types of screening twisted pair tp screening conductor types.
It is electrically superior to flexible cable with 100 shielding effectiveness figure 9.
In my last post i talked about what are cable insulation and various type of insulation.
Because of low cost and long durability coaxial cables were used in computer networking for nearly two decades 80s and 90s.
Electrical cable is a wire which is helps to conduct the current in the circuit.
Generally lower loss extended frequency range and uniform impedance.
Typical outer conductors are.
Electrical wires and cable have markings stamped or printed on their insulation or outer sheathing.
Mainly in the cable industry we use copper atc abc and aluminum conductors for power cables there are different types of a conductor as class 1.
Coaxial cables have been in use for the last four decades.
Specifications of coaxial cables.
Cable types and specifications semi rigid cables semi rigid coaxial cable has a solid outer conductor and is manufactured by drawing seamless tubing over the insulating material and center conductor.
Shielded cable used for sensitive electronic circuits or to provide protection in high voltage applications.
Coaxial cables are no longer used to build any type of computer network.
Twin lead this type of cable is a flat two wire line.
Conductor sizes are.
This type of cable can easily flex and it is designed to handle low level voltages.
From unshielded power or control cable used in areas not prone to interference e g.
Below are common cables you may use in your projects.
But in the overhead line we use copper aluminium aluminium conductor with steel reinforced acsr galvanised steel and cadmium copper.
