Klappentext An introduction to a cutting-edge, environmentally friendly insulation material The installation and maintenance of high-voltage cables is an infrastructure problem with potentially major environmental impacts. In recent years, polypropylene has emerged as an environmentally friendly material for insulating high-voltage cables, particularly HVDC power cables and HVAC power cables. Polypropylene Cable Insulation begins with an introduction to high-voltage cables and the development of polypropylene insulation before describing the dielectric properties and applications of this insulation in both HVDC and HVAC contexts. The result is a thorough, accessible guide to an essential part of any environmentally friendly power grid. Readers will also find: Detailed explorations of the relationship between space charge behaviors and trap characteristics Discussion of topics including polarization and dielectric relaxation, electrical treeing degradation, partial discharge, and more Graphs and tables illustrating experimental results Polypropylene Cable Insulation is ideal for electrical power engineers, power transmission system operators, and any engineers or researchers working in power transmission and/or distribution cables.
