The CFW series busbar, as a high current transmission and distribution system, is mainly used for the connection between power transformers, low-voltage distribution panels, and heavy loads. It has the characteristics of fast installation, convenient use, and reliability, and is suitable for power supply in automotive manufacturing, motor manufacturing, industrial furnaces, and high-rise buildings. At the same time, CFW Bus duct system uses fire barriers when passing through the wall, which can prevent smoke, fire and heat from spreading to adjacent rooms or floors through Bus duct units in case of fire hazard, and even prevent water penetration during fire fighting. CFW Bus duct system is widely used in industrial and mining enterprises as an ideal large current transmission and distribution equipment.
