Book Description
Electrical Power Cable Engineering, Second Edition remains the foremost reference on low- and medium-voltage electrical power cables, cataloging technical characteristics and assuring success for cable manufacture, installation, operation, and maintenance. While segments on electrical cable insulation and field assessment have been revamped to reflect industry transformations, new chapters tackle distinctive topics like the location of underground system faults and the thermal resistivity of concrete, proving that this expanded edition lays a sound foundation for engineering decisions. It deconstructs the external variables affecting conductor, insulation, and shielding design.

Book Description
This text covers the computation of current ratings of electric power cables, a procedure essential in the determination of the maximum current a power cable can carry without overheating. It also helps engineers determine the cable size and type in order to prevent the need for re-installation.

Book Description
Power and communication cables are frequently installed adjacent to each other, and hybrid cables that contain both power conductors and communication lines are increasingly popular. Power and Communication Cables is a convenient, single-source volume written for utility maintenance engineers, cable production and design engineers, and students to expand their knowledge of both types of cables in the power and communications fields. With contributions from leaders in the field, this book presents a detailed treatment of solid-liquid, polymeric, compressed gas, and cryogenic cables used in power transmission and distribution. In the area of communication, the contributors address the use of metallic conductor multipair and coaxial cables, as well as optical fiber cables. Power and Communication Cables provides in-depth discussion of the design, manufacture, testing, installation, and operation of power and communication cables. You will find essential information on the properties of materials and learn how they influence cable characteristics. Moreover, this interdisciplinary reference provides theoretical and practical insights into various aspects of cable engineering in both power and communication systems.

Book Description
Power Cable Technology provides a precise understanding of the design, manufacture, installation, and testing of a range of electric power cables—from low-voltage, 1,000/1,100V cables to extra-high-voltage, 400kV cables—with reference to future trends in the industry. The authors’ mantra is: know your cable. Thus, the book begins with a comprehensive overview of power cable design and manufacturing through the ages, and then: Describes the characteristics of the materials currently used in the production of various power cables Explains how to calculate the die orifice for drawing wires, how tolerance in manufacturing affects material weight and consumption, and how and why lubricants are used Addresses the formation, stranding, and insulation of the electrical conductors, as well as the sheathing, armouring, and protective covering of the power cables Delivers an in-depth discussion of quality systems, quality control, and performance testing Covers the many nuances of cable installation, including laying, jointing, and terminating Throughout, the authors emphasise consonance between design theory and practical application to ensure production of a quality power cable at a reasonable cost. They also underscore the importance of careful handling, making Power Cable Technology a must read for power cable engineers and technicians alike.

Book Description
Rating of Electric Power Cables in Unfavorable Thermal Environment is the first text to provide you with the computational tools and techniques needed to successfully design and install power cables in areas affected by such factors as outside heat sources, ground moisture, or impediments to heat dissipation. After thoroughly reviewing standard rating models, the author discusses several new techniques designed to improve cable ampacity, as well as new computational techniques for analysis of cyclic loads. To facilitate computational tasks he utilizes six representational model cables throughout the book, including transmission-class, high-voltage, distribution, and bundled types. End-of-chapter summaries, liberal numerical examples, and practical, real world applications make this text a valuable resource for making better design and operation decisions.

Book Description
A conductor is a piece of metal used to conduct electricity, known colloquially as an electrical wire. Wires are very good conductors, which mean that they have very little resistance. In fact, their resistance is so small that often we consider it to be zero. (In other words, we often treat wires as perfect conductors).In United States, conductors are measured by American wire gauge (abbreviated AWG) for smaller ones, and circular mils for larger ones. To give you some idea how thick these wires are; AWG 0000 wire is about 11.7 millimeters in diameter (a little less than one-half inch thick) and at the opposite end of the scale, AWG 40 is less than 0.1 millimeters in diameter (about as thick as a strand of hair from your head). The wiring inside the walls of your home is usually AWG 10 or AWG 12 wire. Of the metals commonly used for conductors, copper, has a high conductivity. Silver is more conductive, but due to cost it is not practical in most cases. Compared to copper, aluminum has worse conductivity per unit volume, but better conductivity per unit weight. In many cases, weight is more important than volume making aluminium the 'best' conductor material for certain applications. For example, it is commonly used for large-scale power distribution conductors such as overhead power lines. Conductors are usually surrounded by and/or supported by insulators and the insulation determines the maximum voltage that can be applied to any given conductor. The ampacity of a conductor, that is, the amount of current it can carry, is related to its electrical resistance; a lower-resistance conductor can carry more current. The resistance, in turn, is determined by the material of the conductor and its size. For a given material, conductors with a larger cross-sectional area have less resistance than conductors with a smaller cross-sectional area.This 3-hr Quick Book provides general requirements, classifications and application information for electrical conductors. The course is based entirely on Naval Education and Training Materials (NAVEDTRA 14176), Electricity and Electronic Training Series; Module-4 and covers Chapter 1 titled “Electrical Conductors”. Learning ObjectiveAt the conclusion of this course, the reader will be able to:• Recall the definitions of unit size, mil-foot, square mil, and circular mil. • Define specific resistance and recall the three factors used to calculate it in ohms. • Describe the proper use of the American Wire Gauge when making wire measurements. • State the factors required in selecting proper size wire. • State the advantages and disadvantages of copper or aluminum as conductors. • Define insulation resistance and dielectric strength. • Identify the safety precautions to be taken when working with insulating materials. • List the most common insulators used for extremely high voltages. • Recall the design and use of coaxial cable.
