The demand for high-performance submarine power cables is increasing as more and more offshore wind parks are installed, and the national electric grids are interconnected. Submarine power cables are installed for the highest voltages and power to transport electric energy under the sea between islands, countries and even continents. The installation and operation of submarine power cables is much different from land cables. Still, in most textbooks on electrical power systems, information on submarine cables is scarce. This book is closing the gap. Different species of submarine power cables and their application are explained. Students and electric engineers learn on the electric and mechanic properties of submarine cables. Project developers and utility managers will gain useful information on the necessary marine activities such as pre-laying survey, cable lay vessels, guard boats etc., for the submarine cable installation and repair. Investors and decision makers will find an overview on environmental aspects of submarine power cables. A comprehensive reference list is given for those who want further reading.

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.

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.

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.

How high energy consumption transformed postwar Phoenix and deepened inequalities in the American Southwest In 1940, Phoenix was a small, agricultural city of sixty-five thousand, and the Navajo Reservation was an open landscape of scattered sheepherders. Forty years later, Phoenix had blossomed into a metropolis of 1.5 million people and the territory of the Navajo Nation was home to two of the largest strip mines in the world. Five coal-burning power plants surrounded the reservation, generating electricity for export to Phoenix, Los Angeles, and other cities. Exploring the postwar developments of these two very different landscapes, Power Lines tells the story of the far-reaching environmental and social inequalities of metropolitan growth, and the roots of the contemporary coal-fueled climate change crisis. Andrew Needham explains how inexpensive electricity became a requirement for modern life in Phoenix—driving assembly lines and cooling the oppressive heat. Navajo officials initially hoped energy development would improve their lands too, but as ash piles marked their landscape, air pollution filled the skies, and almost half of Navajo households remained without electricity, many Navajos came to view power lines as a sign of their subordination in the Southwest. Drawing together urban, environmental, and American Indian history, Needham demonstrates how power lines created unequal connections between distant landscapes and how environmental changes associated with suburbanization reached far beyond the metropolitan frontier. Needham also offers a new account of postwar inequality, arguing that residents of the metropolitan periphery suffered similar patterns of marginalization as those faced in America's inner cities. Telling how coal from Indian lands became the fuel of modernity in the Southwest, Power Lines explores the dramatic effects that this energy system has had on the people and environment of the region.

From simple to sculptural, the original cable patterns explored in this must-have resource create a foundation of techniques for designing signature knitwear. Basic twisted stitches, complex interpretations of cables, reversible cables, adding texture and color, turning stitches around, constructing cables with I-cord, and wrapping stitches to create the illusion of cables are some of the integrated techniques detailed in this guide. Contained within are more than 15 original cable patterns for pullovers, jackets, bags, socks, and accessories. Also included is information on a new charting system for predicting cable behavior as well as tips on cabling without a cable needle, choosing the best yarns for specific cable effects, and designing original cable patterns.
