Surface conductive paste coating process of Electrical Grade Aluminum Bus Bar
 
(1) with a file or a fine emery cloth (paper) finely polished coated surface (electrical connection interface), remove burrs and hemp dot (such as may prevent the coating surface is very smooth process, it doesn't matter if there is a small pitting); 

 
(2) Wipe grease on the coated surface with no water alcohol, gasoline or acetone; 
 
(3) after the coating surface smooth, clean, according to the following procedure for coating lap: precoating - thin layer of conductive paste - use wire brush in the precoating contact surface of conductive paste to wipe to use cotton (cloth) wipe the precoating conductive paste, then coated with conductive paste - 0.1 ~ 0.2 MM thick will tighten can contact overlap (without bolts contact, knife switches, plug contact according to the normal joint). 
 
Electrical Grade Aluminum Bus Bar is in processing, besides want to be good at the lap of the bus bar, also deal with the following specific craft. 
 
1. Line bending and copper Bus Bar, direct use of bending tools and equipment; 
 
2. The hardness of Aluminum Bus Bar is less than that of copper row, so special aluminum exhaust punching die must be used. 
 
3. There are more burrs after punching holes in the Aluminum Bus Bar, and it needs to be inverted with a special hole drill bit. 
 
4. The whole batch of heated shrinkage insulation (such as low pressure cabinet using Aluminum Bus Bar, all thermal insulation of low voltage cabinet, such as high pressure cabinet using Aluminum Bus Bar, all thermal shrinkage insulation);The heat shrinkable material wants to choose thinner, had better use the thermal shrinkage material that press phase-line mark color.
