The book "Handbook for the calculation of wires and cables" by F. F. Karpova is an indispensable assistant for engineers, electricians and engineering students seeking a deeper understanding of the basics of electrical systems design. This guide is not just a collection of formulas and tables; it is a holistic guide that covers all aspects of the selection, calculation and application of wires and cables in various operating conditions. In this work, Karpov shares his many years of experience, offering readers not only theoretical knowledge, but also practical recommendations. The book begins with the basics, such as the physical properties of the materials from which the wires are made, and their effects on electrical parameters. Next, the author delves into more complex topics, including the calculation of wire sections, the choice of cables for various types of loads and conditions, as well as safety and overload protection issues. Each section is written with clarity and accessibility, which makes the material understandable even for those who are just starting their way in electrical engineering. This book will be of interest not only to professional electricians, but also to students of technical universities who study electrical engineering and related disciplines. It will be an excellent addition to the training materials and will help to consolidate theoretical knowledge in practice. The guide will also be useful to designers working in the field of construction and modernization of electrical systems, as well as those who are engaged in the repair and maintenance of electrical installations. The topics raised in the book cover a wide range of issues, such as the choice of cables for residential and industrial premises, the features of laying wires in various conditions, as well as the impact of temperature and environment on their operation. Karpov emphasizes the importance of choosing the right wire sections to prevent overheating and ensure the reliability of electrical systems. In this context, the book becomes not just a reference book, but a real textbook that can save from many errors and misunderstandings. The author's style is simple and accessible. F. F. Karpov is able to explain complex things in simple language, which makes his books especially valuable for a wide audience.
