The safe operation of dry-type air-core reactor, as a key element in power system, is of great importance to the power transmission reliability. In this paper, the structure characteristics of dry-type air-core reactor and thermal endurance properties of insulation material are described, the material and structure factor affecting the endurance of reactor, the influence of thermal and mechan- ical load to the structure and insulation coordination are analyzed. The temperature rise limit specifi- cations of China National Standard for different reactors are introduced; the influence of processing methods and design to its safe operation are presented; the operation maintenance and daily inspec- tion for assuring safety of the reactor are put forward.
