This book concentrates on the mechanical aspects of distribution wood pole lines, including live line working, environmental influences, climate change and international standards.
A general overview of the use of utility distribution poles, including for electric supply and communications applications Overhead Distribution Lines: Design and Applications provides information on the design and use of power and communication distribution lines. An excellent resource for those in the power and communication utilities industry, this book presents information on the physical characteristics of utility poles, overhead supply and communication cables, installation practices, joint-usage issues, and safety rules, including the National Electrical Safety Code (NESC), California-specific rules, and others. It describes how to select the proper poles for specific applications. The especially valuable final chapter provides examples showing how it all works in practice, providing a background allowing more effective use of related industry software. Rather than delving into detailed design and installation techniques, this book serves as an overview for engineers and non-technical audiences alike. At the same time, it serves as a compendium of technical information not readily available elsewhere. This unique book: Offers an overview of pole structures, pole installation and maintenance, wires and cables, and cable installation and maintenance—with examples Provides information on national standards documents such as the National Electrical Safety Code (NESC), ANSI O5.1, California General Order 95, and more Explores the "sag–tension" relationship between wires and poles Includes appendices that cover properties of messenger strands, wireless attachments, solution of equations to determine sag, under uniform and point loads Overhead Distribution Lines: Design and Applications offers readers an understanding of the basic principles and various issues related to electric supply and communications distribution lines. It is a valuable resource for utility engineers, as well as those without a technical background.
The only book containing a complete treatment on the construction of electric power lines. Reflecting the changing economic and technical environment of the industry, this publication introduces beginners to the full range of relevant topics of line design and implementation.
This book covers structural and foundation systems used in high-voltage transmission lines, conductors, insulators, hardware and component assembly. In most developing countries, the term “transmission structures” usually means lattice steel towers. The term actually includes a vast range of structural systems and configurations of various materials such as wood, steel, concrete and composites. This book discusses those systems along with associated topics such as structure functions and configurations, load cases for design, analysis techniques, structure and foundation modeling, design deliverables and latest advances in the field. In the foundations section, theories related to direct embedment, drilled shaf ts, spread foundations and anchors are discussed in detail. Featuring worked out design problems for students, the book is aimed at students, practicing engineers, researchers and academics. It contains beneficial information for those involved in the design and maintenance of transmission line structures and foundations. For those in academia, it will be an adequate text-book / design guide for graduate-level courses on the topic. Engineers and managers at utilities and electrical corporations will find the book a useful reference at work.
The definitive guide to distribution and transmission line technology--fully updated Completely revised to reflect the 2012 National Electrical Safety Code (NESC), The Lineman's and Cableman's Handbook, 12th Edition, provides in-depth information on overhead and underground distribution and transmission lines. The latest OSHA, ANSI, and ASTM standards are emphasized throughout. This authoritative resource presents basic principles, equipment, standards, and safety regulations, allowing electrical workers to avoid costly errors, diagnose and repair power failures, and ensure optimum safety. A wealth of illustrations and photographs make it easy to understand the material, and self-test questions and exercises help reinforce key concepts. Comprehensive coverage includes: Electrical principles and systems * Substations * Circuits * Construction * Wood-pole, aluminum, concrete, fiberglass, and steel structures * Distribution automation * Emergency system restoration * Unloading, hauling, erecting, setting, and guying poles * Insulators, crossarms, and conductor supports * Line conductors * Distribution transformers * Lightning and surge protection * Fuses * Switches, sectionalizers, and reclosers * Voltage regulators * Transmission tower erection * Stringing, sagging, and joining line conductors * Live-line maintenance * Grounding * Street lighting * Underground distribution * Vegetation management * Distribution transformer installation * Electrical drawing symbols * Single-line and schematic diagrams * Voltage regulation * Units of measurement, electrical definitions, electrical formulas, and calculations * Maintenance of transmission and distribution lines * Rope, knots, splices, and gear * Climbing and wood poles * Protective equipment * OSHA 1910.269 * Resuscitation * Pole-top and bucket rescue
This collection contains 36 papers on structural issues in the electrical transmission industry that were presented at the 2006 Electrical Transmission Conference, held in Birmingham, Alabama, October 15-19, 2006.
