Abstract: The methods to improve the transmission capacity of overhead lines mainly include the methods of increasing the cross section of conductors, adopting new capacitive conductors, increasing the capacity of existing conductors and technical transformation, etc.This paper analyzes the research and application status of these technologies, and focuses on the dynamic real-time capacity-uprating technology. Based on the capacity-uprating technology of overhead high-voltage lines, the main technical bottlenecks and development trends are discussed. And this paper’s aim is to provide relevant theoretical basis for the industrialization, economization and sustainable development of line capacity-uprating.

Key words: overhead high voltage line; capacity-uprating of line; dynamic real-time capacity-uprating
