Features: With the construction and development of urban and rural power distribution networks, the rapid growth of power distribution volume nationwide, and the increasing workload of 220kV and below power distribution tasks, it is essential to ensure the safe, economical, and reliable construction and operation of 220kV and below power distribution networks. Based on the spirit of urban and rural power grid construction and transformation and current national industry standards, combined with the actual situations of power distribution network and equipment planning, design, installation, construction, operation, maintenance, and testing, a set of "Power Distribution Technology Handbook" has been organized for writing, divided into three volumes: Low Voltage Part, 10-35kV Part, and 110-220kV Part. This book is the "Power Distribution Technology Handbook (10-35kV Part)" volume, primarily introducing the design of 10-35kV distribution line measurements, meteorological selection of phase conductors, overhead conductors and lightning rods, pole tower and foundation grounding, insulators and hardware, etc. It also covers power distribution line construction tools, processes, and construction design, re-measurement and layout, foundation and pole tower assembly, overhead line installation, insulated wire selection, and construction management. Additionally, it includes power distribution line inspection, lightning protection and pollution flash prevention measures, voltage quality and adjustment, line loss calculation and loss reduction measures, and operation management. The handbook also discusses power distribution line maintenance requirements, insulator and hardware replacement, tension wire and cross-arm replacement, pole tower maintenance and heightening, grounding maintenance and foundation upkeep, conductor and lightning rod maintenance, and live-line maintenance. Furthermore, it covers the types and characteristics of power cables, cable laying, splicing of cable heads, raw materials for epoxy resin cable heads, cable terminal heads, intermediate joints, heat-shrinkable cable heads, and common tools. The handbook also explains the principles and structures of power distribution transformers, operation and fault diagnosis, testing and installation selection, parameters, installation selection, and technical requirements of oil-less, vacuum, and SF6 circuit breakers and their operating mechanisms, operation and fault handling, testing and maintenance. It also includes the parameters, structures, selection, and coordination requirements of reclosers and load switches, as well as the structural wiring, selection, installation, and commissioning requirements of switchgear, prefabricated substations, capacitors, fuses, current transformers, lightning protection equipment, etc. This handbook can serve as a reference tool for production personnel, workers, technicians, and management staff in urban power supply enterprises, district and county power supply enterprises, rural power supply enterprises, and distribution substations engaged in power distribution planning, design, installation, construction, operation, maintenance, and experimental inspection. It can also be used as a reference book for power distribution workers, technicians, and relevant professional students in industrial and construction enterprises.
