Technical requirements for hig線白h and low voltage bus d歌鐘uct

1. The dense bus duct provide身拍d by the high and low voltage b吃街us duct has good dynamic and t問她hermal stability and large transmi雪樂ssion capacity. The conductive bar ad多地opts 99.99% copper bar. The友輛 selection of copper bar meets 坐場the gb5585 standard. The in為河sulating material is 還相selected, with good insulation perfo快吧rmance and fire resistance and 子樹aging life of more than 40 years. 2.快銀 The overlapping part of copper bar sh那服all be silver plated and 體志embossed. 3. The shell of身窗 dense bus duct is made of cold-rolled水要 steel plate. The shell s錢從hall have sufficient strength, 在水good surface treatment and員影 anti-corrosion performance, flat 秒信outer surface and beautiful c技近olor. Cold galvanizing, ra厭也l7032 epoxy resin powder 在西electrostatic spraying and matte or日科ange peel are added, and the inner 討化surface is cold galvanizing. 4. The lo有地w-voltage dense bus adopts single-ch有請ip copper bus conduct亮行or, its section and s草車upporting span meet 能民the requirements of 物報short-circuit thermal stability 兒可and short-circuit dynamic s城西tability, support span and avoid re火問sonance zone, and the straight-line se秒子ction and continuous secti短工on of bus copper conductor is 6m請吧. 5. The bus conductor l但人ayout shall consider the balance o森銀f conductor current distribut問笑ion, and the current imb我空alance shall not exceed 4% in phas還信e and 5% between phases. 6. The 一能specific size and tra秒學nsition connection device of the 鐘人low-voltage dense bus c醫紙onnected to the transf國銀ormer and switch cabine山志t shall be organized by the ow關水ner to participate in the liais低請on meeting attended by the De從機sign Institute, the 離拍switch cabinet factory, the tran相國sformer factory and the supplier and見黃 demander. After determini秒錯ng the connection mode, the supplier冷低 of high-voltage and low-voltage bus du裡微ct shall conduct on-s水那ite measurement accor志都ding to the minutes of the liai笑吧son meeting, and consider the conven長微ience of maintenance快老 and disassembly of joints.
