Abstract: Cable network is an important component of intelligent electricity distribution network. Its planning，
construction ，operation and maintenance are not only confined to power system，but also related to the coordination
between underground resources of multi-energy systems ，and the overall planning and construction of regional underground
pipelines. Therefore，it is very important to study how to effectively improve the lean management level of distribution cable
network. As a distributed shared database technology， blockchain has the characteristics of decentralization，
transparency，fairness and openness，which coincide with the requirements of the lean management on distribution cable
network. The management demand of distribution cable network is analyzed from planning and construction to operation
and maintenance. Then，the application direction of the blockchain technology in the lean management of distribution
cable network is explored from three dimensions，object，function and attribute. And by analyzing two application
scenarios of blockchain which are the occupation certification of underground pipelines and the fusion of decentralized
multi-agency and multi-energy systems，the application mode of blockchain technology in the lean management of
distribution cable network is illustrated. Finally，the opportunities and challenges of the blockchain technology in
developing lean management of distribution cable network are analyzed and summarized.
