The understanding of transmission line structural loads continues to improve as a result of research, testing, and field experience. Guidelines for Electrical Transmission Line Structural Loading, Third Edition provides the most relevant and up-to-date information related to structural line loading. Updated and revised, this edition covers weather-related loads, relative reliability-based design, and loading specifics applied to prevent cascading types of failures, as well as loads to protect against damage and injury during construction and maintenance. This manual is intended to be a resource that can be readily absorbed into a loading policy. It will be valuable to engineers involved in utility, electrical, and structural engineering.
Prepared by the Task Committee on Electrical Transmission Line Structural Loading of the Electrical Transmission Structures Committee of the Special Design Issues Technical Administrative Committee of the Structural Engineering Institute of ASCEFully revised and updated, Guidelines for Electrical Transmission Line Structural Loading, Fourth Edition, MOP 74, provides the most current and relevant loading concepts and applications specific to transmission line design. A valuable resource for the development of a loading philosophy for electrical transmission structures, the information presented can be applied to an individual project or at a regional level. Key topics addressed in this manual areUniform procedures and definitions used in the industry for the calculation of loads,Design procedures addressing uniform levels of reliability for transmission lines,Up-to-date techniques for quantifying weather-related loads,Procedures for calculating design loads and determining their corresponding load factors, Updated techniques for quantifying wire system and other non-weather-related loads,Failure containment philosophy,andPractical examples providing more detail on the application of load recommendations. This Manual of Practice will be an important guide to engineers involved in electrical utility and structural engineering.
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.
This collection contains 46 papers discussing electrical transmission line engineering presented at the Electrical Transmission in a New Age Conference, held in Omaha, Nebraska, on September 9-12, 2002.
This Standard provides a uniform basis for the design, detailing, fabrication, testing, assembly, and erection of steel tubular structures for electrical transmission poles. These guidelines apply to cold-formed single- and multipole tubular steel structures that support overhead transmission lines. The design parameters are applicable to guyed and self-supporting structures using a variety of foundations, including concrete caissons, steel piling, and direct embedment. Standard ASCE/SEI 48-11 replaces the previous edition (ASCE/SEI 48-05) and revises some formulas that are based on other current industry standards. This Standard includes a detailed commentary and appendixes with explanatory and supplementary information. This Standard will be a primary reference for structural engineers and construction managers involved in designing and building electrical transmission lines, as well as engineers and others involved in the electric power transmission industry.
Primarily for the three parties named in the subtitle, this manual offers information and recommendations on principles and procedures that have been shown effective in enhancing the quality of construction projects the projects themselves not the finished product. Among other aspects, it discusses
This book covers structural and foundation systems used in high-voltage transmission lines, conductors, insulators, hardware and component assembly. Furthermore, this text provides the essential fundamentals of transmission line design. It is a good blend of fundamental theory with practical design guidelines for overhead transmission lines, providing the basic groundwork for students as well as practicing power engineers, with material generally not found in one convenient book. Featuring design problems with solutions 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 to be a useful reference at work. This book presents the current state of electrical technology applied to the calculation and design of high voltage power lines, both aerial and underground, by means of an original approach based on the simple exposure of theoretical bases that allow the reader to apply them in the subsequent resolution of numerous real engineering examples. The examples in each chapter are developed in detail and have been selected in order to address the diversity of electrical and mechanical calculations required by the design of high voltage power lines. The book consists of chapters dedicated to the electrical design of lines, mechanical calculation of conductors, supports and foundations, design of grounding facilities and calculation of underground lines. There is no other book that gathers, in such a detailed way and with a focus eminently practical, all aspects related to the design of high voltage lines.
