1. Safe and reliable: the compartments in the cabinet are all independent small compartments separated from each other; perfect "five prevention" interlocking function, reliably preventing misoperation and erroneous entry into the live interval; quick closing grounding switch to achieve reliable protective grounding.
2. Flexible solutions: The switch cabinet has a complete set of solutions, which can flexibly form various system solutions to meet customer requirements; according to the application environment and special requirements, it can also provide high altitude series products, double bus series and various non-standard solutions.
3. Strong practicability: the cabinet shell has high sealing strength to prevent the equipment from being invaded by sundries and insects.
Intelligent Logistics System
Three-dimensional warehousing system: 20-meter high-bay warehouse, storage density increased by 300%; WMS intelligent scheduling, inventory turnover rate increased by 50%.
