Different Types Of Electrical Cables And Their Specifications Pdf

Conductors are of different materials.

Different types of electrical cables and their specifications pdf. 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 are no longer used to build any type of computer network. 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.

Single cable from time to time this name is used for wire submersible cable. But in the overhead line we use copper aluminium aluminium conductor with steel reinforced acsr galvanised steel and cadmium copper. It is also called conductor. Conductors are the only power carrying path in a power cable.

This type of cable can easily flex and it is designed to handle low level voltages. 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. Because of low cost and long durability coaxial cables were used in computer networking for nearly two decades 80s and 90s. In my last post i talked about what are cable insulation and various type of insulation.

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. Different types of electrical cables each have their own specific purposes and applications. Understanding electrical wiring labeling. Today i will discuss the cable classification and specification of electrical cable so let s go.

Nm b cable nm stands for non metallic which refers to the flexible typically pvc sheathing surrounding the cable. Electrical cable is a wire which is helps to conduct the current in the circuit. It is electrically superior to flexible cable with 100 shielding effectiveness figure 9. Twin lead this type of cable is a flat two wire line.

Solid class 2 stranded class 5 flexible class 6 extra flexible mostly used for cords and welding etc. Cable is an important object in the electricity. Electrical wires and cable have markings stamped or printed on their insulation or outer sheathing. Various degrees of screening are used according to the cable type and application.

Generally lower loss extended frequency range and uniform impedance. From unshielded power or control cable used in areas not prone to interference e g. Standard wire cable co. Shielded cable used for sensitive electronic circuits or to provide protection in high voltage applications.

Below are common cables you may use in your projects. Typical outer conductors are.
