An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current. A cable assembly is the composition of one or more electrical cables and their corresponding connectors. Cable assemblies can also take the form of a cable tree or cable harness , used to connect many terminals together.

Tables of AWG wire sizes. The table below shows various data including both the resistance of the various wire gauges and the allowable current ampacity based on plastic insulation. The diameter information in the table applies to solid wires. Stranded wires are calculated by calculating the equivalent cross sectional copper area.

Electrical Wires & Cables

A data cable is a cable that provides communication between devices. First of all, I want to tell you why you need to know about the electrical cable classification and specification? Types of Electrical Cable. There are four major types of cables that are used: aluminium, copper, industrial and fiber optic. A wiring connecting between distribution boards.

Figure 1. Twisted-pair cabling has emerged as the dominant network cabling scheme, contributing to the vast expansion in Ethernet use. Late in , the Institute of Electrical and Electronics Engineers IEEE published a new set of standards introducing data-capable twisted-pair cabling for use in 10 Mbps Ethernet systems. The star topology and 10Base-T technology made installing and troubleshooting Ethernet systems much easier, and it made managing them much more efficient. Since that time, twisted-pair cabling has emerged as the dominant network cabling scheme, and has contributed to the vast expansion in Ethernet use that still continues today. There are now a dizzying number of twisted-pair cable types available, corresponding to a dizzying array of standards detailing the configuration and performance specifications needed to support the increasingly faster data rates and larger bandwidths of incoming technologies.

Types of Electrical Wires and Cables

Electrical cable and wires are considered as a same thing. In fact they are quite different. A wire is made of a single electrical conductor while a cable is a group or bundle of multiple wires inside a common sheathing. Both of them are used for carrying electrical current. Nowadays due to the advancement in technology, almost everything is powered by electricity.

Electrical Cable Types, Sizes, and Installation

Electrical cable is a wire that helps to conduct the current in the circuit. It is also called a conductor. Cable is an important object in the electricity. Copper and Aluminum conductors are the two types of electrical cables used in the electrical wiring. But in the overhead line, we use copper, aluminum, aluminum conductor with steel reinforced ACSR , galvanized steel and cadmium copper.


More often than not, the terms wire and cable are used to describe the same thing, but they are actually quite different. Wire is a single electrical conductor, whereas a cable is a group of wires swathed in sheathing. The term cable originally referred to a nautical line of multiple ropes used to anchor ships, and in an electrical context, cables like wires are used to carry electrical currents.
