Bus duct is suitable for power supply systems with AC three-phase four wire,three-phase five wire system,frequency of 50-60HZ,rated voltage up to 660V,and rated working current of 250A-5000A.It undertakes power distribution tasks and is used for connecting low-voltage distribution panels with large and medium-sized loads.It is mainly used in modern workshops,factories,and high-rise buildings.The outer shell of the bus duct is formed by rolling,with a small volume and exquisite appearance,greatly improving the load capacity of the factory.It can carry a load of 60Kg at the center of the bus with a span of 6m,and the deflection does not exceed 10mm.

　　Aluminum alloy bus ducts are made of sufficiently sturdy materials to ensure the safety of transportation and lifting during installation.When using ropes to lift bus ducts,thick cloth or corrugated paper should be placed under stress to protect the bus ducts from damage.When hoisting bus ducts above 2500A,they should be clamped with sturdy wooden boards and tied with ropes to prevent deformation of the bus duct casing.Before connecting the aluminum alloy bus duct,the contact surface or insulation material should be checked for damage,and at the same time,it should be checked for dirt,dust,or other foreign objects.If there are any,they must be cleaned thoroughly.After connecting a complete circuit,if the insulation resistance is found to be abnormal,it is difficult to check the cause again.Therefore,insulation resistance must be tested for every section of the bus duct connected.When installing according to the layout plan,ensure that the dimensions of each section of the installation line,positioning dimensions,reserved section dimensions,and interface section dimensions meet the requirements of the drawings.

　　When the aluminum alloy busbar trunking project is suspended,the ends of the connecting parts must be re wrapped and sealed with plastic cloth to prevent contamination of the joint parts.Fire prevention is very important in high-rise buildings,and fire-resistant barriers should be used for bus ducts in high-rise buildings and horizontal empty walls for fire prevention treatment.At the beginning of a fire,it can prevent smoke,fire,and heat from spreading through the bus duct unit to the monitoring room or floor,and even prevent water leakage during firefighting.The installation of bus ducts is extremely convenient,using connections with automatic compensation and single bolt clamping terminals,with strong adjustability,making the installation process of bus ducts very convenient and flexible,greatly saving installation time.

　　The bus duct is extremely safe and reliable,using a separated air insulation type.The safety clearance and creepage distance between phases are much greater than the standard requirements;The internal insulation components are made of high-strength engineering plastics,which improves the resistance and thermal stability of the bus duct;The special structure adopted by the joint can prevent misoperation during installation;Install a safety barrier at the socket,and only when the barrier is opened can the plug-in box be inserted.When the socket is not in use,the protective baffle can be closed and sealed with lead to prevent dust or foreign objects from entering the socket,and to prevent power from being disconnected from the incoming end of the meter.This improves the protection performance of the busbar duct,prevents misoperation,and greatly enhances the safety performance of the busbar.When plugging in the plug-in box,there is no need to cut off the power supply,and the ground wire is always connected first and then disconnected.
