Requirements for laying wires in bus ducts and reasons for their popularity

Release time:: 2022-03-23 Click count: 674

  Bus ducts are easy and flexible for power distribution,sometimes assembled into busbars or busbars.Bus ducts are usually made of copper,brass,or aluminum metal bars that are both grounded and conductive.Different coating materials provide varying levels of conductivity limits and product lifespan.Busbars can also have various shapes and sizes,which can affect the current carrying capacity of the product.The term'current carrying capacity'refers to the greater amount of current that a conductor can carry before maintaining a critical degradation level.

  The reason for the popularity of bus ducts is to reduce facility costs,as less construction labor means lower installation costs,and electrical experts do not need to make expensive changes and external labor costs.Faster installation speed,as construction projects start and run faster,and can easily and quickly add,remove,or relocate power sources without downtime.The flexibility of the future lies in the fact that certain plug-in units can be disconnected and reconnected without the need for daily maintenance,and can be expanded or reconstructed faster and at lower costs.Environmentally friendly,as busbars typically require less installation materials and plug-in sockets can be reused and repositioned.The improvement of the structural integrity of the busbar system has been proven that changing the shape of the copper busbar can greatly improve efficiency,expose more copper surface area,increase balance current,and reduce its current carrying capacity.

  Bus duct is suitable for communication and exchange of three-phase four wire,three-phase four wire,and three-phase five wire power distribution.Bus duct products have the characteristics of light weight,compact structure,high conveyor current,reliability,and easy installation.The busbar trunking with plug-in sockets can easily locate the branch switch power supply based on the plug-in switch box.When installing the bus duct,it can be immediately received from the transformer to the distribution box,and then immediately received from the low-voltage switchgear as the main distribution line for the distribution system.According to the various bending modules of the bus duct,the installation of the bus system can be carried out in all building constructions,including levels,corners,replacements,and capacity changes.

  The wiring inside the busbar trunking should be connected to the same control circuit's phase and ground wires,and laid in the same metal trunking.The free online cable tray has a required capacity and cannot have connectors.The cables shall be bundled in segments according to the control circuit number,with bundling intervals not exceeding 2m.Different control circuits of the same switch power supply without anti-interference regulations can be laid in the same cable tray.Lines with anti-interference regulations should be protected with baffles or shielded with cable wires,and a grounding device should be installed on the side of the shielded wire cover.When using a multi-phase power supply system,the color tone of the cable sheath of the cable should be the same,that is,the protection zone line(PE line)should be yellow green,the ground wire should be light blue,and the phase lines should be:L1 phase light yellow,L2 phase emerald green,L3 phase bright red,etc.
