Understanding electrical wiring labeling.
Different types of electrical cables and their specifications pdf.
Below are common cables you may use in your projects.
Types of screening twisted pair tp screening conductor types.
It is also called conductor.
Electrical wires and cable have markings stamped or printed on their insulation or outer sheathing.
From unshielded power or control cable used in areas not prone to interference e g.
Generally lower loss extended frequency range and uniform impedance.
Shielded cable used for sensitive electronic circuits or to provide protection in high voltage applications.
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.
Nm b cable nm stands for non metallic which refers to the flexible typically pvc sheathing surrounding the cable.
Conductors are of different materials.
It is electrically superior to flexible cable with 100 shielding effectiveness figure 9.
Various degrees of screening are used according to the cable type and application.
Within a metal control cabinet to foil or braid shielded cable for areas of high emi or electrical interference.
Single cable from time to time this name is used for wire submersible cable.
Conductors are the only power carrying path in a power cable.
Because of low cost and long durability coaxial cables were used in computer networking for nearly two decades 80s and 90s.
Different types of electrical cables each have their own specific purposes and applications.
Copper and aluminium conductors are the two types of electrical cables used in the electrical wiring.
Coaxial cables have been in use for the last four decades.
Electrical cable is a wire which is helps to conduct the current in the circuit.
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.
Solid class 2 stranded class 5 flexible class 6 extra flexible mostly used for cords and welding etc.
Typical outer conductors are.
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.
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.

Cable is an important object in the electricity.
Twin lead this type of cable is a flat two wire line.
In my last post i talked about what are cable insulation and various type of insulation.
But in the overhead line we use copper aluminium aluminium conductor with steel reinforced acsr galvanised steel and cadmium copper.
This type of cable can easily flex and it is designed to handle low level voltages.
Standard wire cable co.
Coaxial cables are no longer used to build any type of computer network.
