Abstract: Complete sets of automatic ring network cabinets are generally used to realize distribution network automation for urban 10 kV cable lines. The main difference between the installation method and the complete set of switch cabinet on the column is that the complete set of 10 kV automatic ring network cabinet is assembled in the factory. Therefore, the construction site pays more attention to handover and acceptance. Ensure that the ring main cabinet body, cable head, optical fiber and other facilities can meet the requirements of safe production. Improve the operation reliability of distribution automation equipment and reduce the workload of operation and maintenance.
