Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an inlet and outlet line sealing structure of a power distribution cabinet. Background Art

[0002] A distribution box is an electrical device used to distribute power to different electrical equipment. The main function of a distribution box is to distribute power to ensure safe and stable operation of the circuit. It protects electrical equipment from dangerous situations such as short circuits, overloads, and leakage. The installation and setting of the distribution box must be carried out in strict accordance with relevant standards and specifications to ensure safe use of electricity.
