Abstract: The power transmission and transformation project is an important link in the construction of the power grid, there are safety hazards throughout the construction process, and illegal operations can easily cause casualties. In order to reduce accidents and supervise the reduction of violations on site, this article lists the scenarios where violations are prone to occur during the construction of power transmission and transformation projects, and analyzes the hazards, causes, and solutions of three common violations. This has good reference significance for the construction management of future power transmission and transformation projects.
