How should the market price be calculated for bus ducts and their product design specifications of different types of enterprises?The bus duct is generally divided into three-phase four wire system and three-phase five wire system,as well as a special three-phase three wire and DC system two-phase system.Calculation of copper bars;Before quoting,students need to clarify which line system it is.Then we determine the specifications for selecting copper bars based on the size of the production busbar trunking,and calculate the volume data of the copper bars(the volume calculation is the length of a single copper bar multiplied by the cross-section of the copper bar,and then multiplied by the number of bars.For smaller grounding wire specifications,another calculation can be used).After calculating the volume,multiply it by the unit price of the copper busbar to obtain the price of using busbar trunking copper busbar.

　　Calculation of shell:There are various forms of bus duct shells,including ordinary carbon steel,aluminum magnesium and gold,as well as high-strength extrusion type.The design of ordinary carbon steel shell can be based on the volume of the shell multiplied by the price of the plate.The thickness of the plate material for carbon steel shell needs to be determined according to the size of the bus duct,usually around 1.5mm~2.5mm.Aluminum magnesium and gold,high-strength extrusion type,if not produced by our own company,we need to inquire with these distributors CESKO for pricing.All product casings also need to fully consider the price impact factors of surface information processing.In addition to the language shell,it is also necessary to consider the ampere specifications of the bus duct,the selection of conductor materials,and the number of on-site users to comprehensively analyze and consider its price.

　　The currently popular bus duct structures include air insulated and sandwich sealed types.Air insulation general accessories require insulation pads,heat shrink sleeves,connecting screws,etc.The sandwich dense fittings require insulation pads,heat shrink sleeves,polytetrafluoroethylene films,connecting screws,etc.,and the quantity of secondary insulation pads.The joint part consists of joint copper bars(whose specifications should comply with the specifications of bus duct copper bars)and joint insulation boards.Specific prices can be inquired with Guangdong Cisco General Electric Power Technology Co.,Ltd.
