Types of Overhead Conductor

Conductor is a physical medium to carry electrical energy form one place to other. It is an important component of overhead and underground electrical transmission and distribution systems. The choice of conductor depends on the cost and efficiency. An ideal conductor has following features. It has

Conductor Resistance Test of Electrical Power Cables

This test is used to determine the DC resistance of copper or aluminum conductors . Resistance of a conductor tells us how easily a conductor allows the flow of current through it. Higher the resistance, lesser the current will flow though the conductor. Resistance of a conductor is influenced by co

Wrapping Test for Conductors

This test is done on aluminum wire used as conductor in power cables to determine its ductility. Ductility of a conductor is nothing but the property of how easily it can be wound and twisted. Higher the ductility, easily the material can be wound and twisted without its breaking. This property play

Test for Thickness of Insulation of Power Cable

This test covers the technique to confirm the thickness of insulation and sheath of electric power cables . Adequate thickness of insulation and sheath is provided to power cable meet up the voltage stresses and mechanical stresses imposed on the cable during its service life. The measurement of suc

Tensile Test of Conductors

This test is performed only to confirm tensile strength of aluminum wires used for conductor in electric power cables . This test is significantly performed on conductor material to judge the strength of this material. A cable conductor is often subjected to pull from one end during laying, installi

Annealing Test for Wires and Conductors

This test is normally carried on annealed copper wires, aluminum wires for welding cables and solid conductors of electric power cables. The current carrier conductors of power cable is subjected to twist and bend during laying and installation hence it should be flexible enough to take any desired

Fiber Optic Cable Types & What They Are Used For

What are Fiber Optics Cables Used For? Fiber optic cables (also known as optical fiber cable) are network cables that contain many strands of fine glass fibers known as optical fibers, which are kept well-insulated within the body of the cable. These cables are created for the use of long-distance,

Electrical Power System: What is it? (Power System Basics)

What is a Power System? An electric power system is defined as a network of electrical components used to supply, transfer, and consume electric power. The supply is done through some form of generation (e.g. a power plant ), the transfer is done through a transmission (via a transmission line ) and
