4.1、Procedures and Notice of Equipment Installation
4.1.1、The following tools and equipments should be prepared in advance before installation:
Crane,Wrench,Torque Wrench,Sleeve Wrench(24#、19#、17#、14#）,Screwdriver,Wooden Hammer,Track level bar,Square, Emery paper,Copper Brush(or Steel Brush),Cleaning cloth, Painting equipments,Argon arc welding equipments,Welding Machine,Cleaning tools,Conductive paste,Fluid alant, Asbestos Cloth,Bus location Supporter,Rope or Steel ropes with rubber bushing.上海中级口译官网
4.1.2、The welding of Bus and Shell should be done by qualified
argon arc welder.The filth and Oxide film at the welded junction should be cleaned before welding.The purity of filling welding wire should not be lower than L2(not lower than99.5%).While the ambient temperature is lower than10℃,in order to ensure the quality of welding wire,measurements such as raising temperature before welding and heat prervation during welding should be taken.The total cross ction of welding wire should not be smaller than1.25times of that of the welded conductor’s total ction.
