The frame structure used is highly flexible, and once the structure is assembled, maintenance is no longer required. Different standard components can be installed in the cabinet to meet various requirements. The design of the system and the materials used can prevent the occurrence of fault arc to the greatest extent. Once a fault occurs, the arc can be extinguished in a short time.
