Digital-intelligent technologies are profoundly transforming the construction and management paradigm of ultra-high voltage power transmission and transformation projects. From the perspective of industrialization, this paper elucidates the theoretical connotations and logical connections among digital-intelligent technology, lean construction and quality traceability, analyzes their industrialization value, identifies bottlenecks such as inconsistent standards, data silos, talent shortage and unclear input-output expectations, and proposes promotion strategies from four dimensions to provide reference for the digital-intelligent transformation and high-quality development of the power industry.
