Underground Cable Thermal Backfill documents the proceedings of the ""Symposium on Underground Cable Thermal Backfill,"" held in Toronto, Canada, 17-18 September 1981. The symposium brought together research, design, and installation engineers from utilities, cable manufacturers, and universities to present and discuss developments in the field. The contributions of researchers at the symposium are organized into five chapters. Chapter 1 presents an overview of the state-of-the-art of cable backfill materials and soil thermal property measurements. The papers in Chapter 2 deal with developments in cable backfill materials. These include materials stabilized with moisture substitutes, pumpable materials, and materials stabilized with bound water. Chapter 3 covers thermal property measurements of soils and backfills. Through the automation of measurements and analysis using microprocessor based instruments and better control of experimental conditions, substantial improvements have been made in the area of measurement technology. Chapter 4 reports developments in the study of soil thermal stability and the implication thereof for thermal cable design. Chapter 5 discusses various aspects of thermal cable design, including methods for incorporating historical weather records to predict worst case soil and backfill thermal conductivities. This volume should serve as a useful introduction to the subject of cable thermal design for engineers involved in underground transmission and distribution systems.

The successful transmission of electrical power beneath the surface of the earth depends on a number of factors including ambient temperature, sheath bonding, cable laying depth, and especially the formation of dry zones around underground cables. Environmental Impacts on Underground Power Distribution studies the factors which affect the maximum current rating of subterranean power cables as well as various methods to maximize electrical current transmission. Focusing on the latest tools, methodologies, and research in the field, this publication is designed for use by electrical engineers, academicians, researchers, and upper-level students.

Fully updated, Electrical Power Cable Engineering, Third Edition again concentrates on the remarkably complex design, application, and preparation methods required to terminate and splice cables. This latest addition to the CRC Press Power Engineering series covers cutting-edge methods for design, manufacture, installation, operation, and maintenance of reliable power cable systems. It is based largely on feedback from experienced university lecturers who have taught courses on these very concepts. The book emphasizes methods to optimize vital design and installation of power cables used in the interrelated fields of electrical, mechanical, and, to some extent, civil engineering. An in-depth exploration of power cable characteristics and applications, it illustrates the many factors that can hinder real-world cable performance. Content focuses on low and medium voltages, considering that these are used for the majority of cables in service globally. This edition also details techniques for testing shielded power cable systems in the field, demonstrating how conductor material size and design depend on ampacity, voltage regulation, and other factors. Covering everything from manufacturing to testing, this resource will benefit: Cable engineers and technicians (working for investor-owned utilities, rural electric cooperatives, and industrial manufacturers) who need to improve their oversight and understanding of power cables Universities that offer electrical power courses Professionals who must master new power cable terminology, engineering characteristics, and background information that will aid them in their decision making responsibilities The author is a life fellow of the IEEE and one of the original developers of industry standards for cables and accessories. To simplify field fundamentals and techniques for less experienced readers, his book contains new, updated, and expanded chapters and an extensive glossary, in addition to useful references, tables, equations, and photographs. More experienced engineers will appreciate the book’s invaluable updates on the emerging materials, products, and concepts driving their dynamic field.
