Busbar refers to a product made of high conductivity copper(copper bars)and aluminum materials,used for transmitting electrical energy and having the ability to collect and distribute electricity.The main conductor used for transmitting electrical energy in nuclear power plants or substations.Through it,the electrical energy output from generators,transformers,or rectifiers is transmitted to various users or other substations.Bus duct is a sealed metal device composed of copper and aluminum bus columns,used to distribute large power to various components of a distributed system.The busbar trunking system is an efficient distribution device for conveying current,especially suitable for the increasingly high buildings and large-scale factories with the need for economical and fair wiring.

　　Busbar duct accessories include plug-in box kits,plug-in interfaces,connectors,elbows,flange ends,cable entry boxes,busbar end seals,horizontal brackets,spring brackets,flexible connections,variable capacity joints,tees(T-joints),elbows(horizontal and vertical),expansion joints,which may not be used on every project.It depends on the situation.Low voltage dense busbar trunking consists of straight sections,elbows,tees,flanges,cable transfer boxes,terminal seals,and plug-in boxes.Connectors are generally included in the quotation for straight sections,although some manufacturers may quote separately.Straight sections,elbows,tees,flanges,cable junction boxes,terminal seals,plug-in boxes,connecting copper plates,insulation boards,insulation through screws.

　　Scale accessories refer to auxiliary components randomly equipped.Although the scale configuration of each model is different,common scale configuration components include memory and paper supply box.Of course,the size of the memory and the capacity of the paper feed box vary for different models.The situation of scale configuration can be understood by consulting the product manual.If there is a lack of scale configuration,it will to some extent affect the use and functionality of the product.Optional accessories refer to components that can enhance and improve product functionality beyond the scale configuration,and require additional purchase.Unlike the scale configuration,not using optional accessories will not affect the basic functionality of the product.There are many types of optional accessories,and different products support different optional products.Therefore,when choosing optional accessories,you should consult the product instructions in advance to avoid being unable to use them.

　　The spacing between support points for the horizontal laying of sealed busbars should not exceed 2.5m;When laying vertically,special attachments should be used to support the floor slab.The vertically laid sealed busbar should be fixed with brackets when the incoming box and the end are suspended.Expansion joints should be installed when the length of the blocked busbar in a straight line exceeds 40m.At the expansion or settlement joints where the busbar crosses the building,the mechanical joint processing of the busbar slot accessories should adopt measures that are suitable for the movement of the building structure.The connection of the enclosed busbar should not be set at the location where it passes through the floor or wall.Fire isolation measures should be taken when passing through firewalls and fire-resistant floors.The overlapping surfaces between busbars and between busbars,as well as between busbars and electrical appliances,should be cleaned and coated with electrical compound grease.
