  Guidance for model selection:
  As shown in the above table,current-carrying capacity of insulated flexible busbars is depending on sectional dimension and temperature of busbar.Therefore,the following elements shall be taken into consideration:
  ①Current-carrying capacity(A)
  ②Acceptable busbar heating(△T)
  ③Acceptable busbar width(W)
  The computation formula of busbar heating(△T)is as follow:
  △T=Ta-Tc
  Tc:Ambient temperature.
  Ta:Busbar temperature after being charged with electricity(Important note:Ta≤105℃for electrical equipment in general).
  Sample of selection(for reference only):
  Requirements:The ambient temperature for the equipment operation is 40℃,current carrying capacity of the copper bar shall be 510A,the highest temperature of copper busbar does not exceed 100℃,and width of copper busbar shall not exceed 40mm.
  Model selection:According to the formula,the highest temperature allowed could be woked out as 60℃(100℃-40℃=60℃),so the flexible copper busbar with specification of 32×1×4 could be selected:copper busbar of this specification has a temperature rise of 50A under the load current of 520A,so this selection is possible,and there is sufficient margin of safety.

  Over 50 clients all over the world,especially in America
  Two production lines
 
  Strengths of insulated flexible Cu busbars compared with flexibles
  A:Lead time:less processing procedure,shorter lead time,more suitable for mass production
  B:Appearance properties:the insulated flexible Cu busbars do not need the process of high-temperature molecular welding,this can be avoided internal oxidation;Finished flexibles need electroplating,this may cause acid corrosion.
  C:Flame resistance:the insulation flame retardant grade is UL94-V0,this is the highest flame resistance grade.But,welding flexible is setting heat-shrink tube on external,and the flame resistance grade of heat-shrink tube is VW-1.So,the insulated flexible Cu busbars are better than flexibles.
  D:Cost analysis:to compared with flexibles,the process of flexibles is complex,and the cost of surface treatment is higher,while,due to the strict environmental requirements,all plating are centralized management in electroplating industrial district,so the distance is longer,and the cost of transportation is higher.However,for the flexible insulated bus bars,we only purchase the electroplated copper strip,and we what the process we only need to do is processing(bending),so the process is less,the delivery is faster,and the cost is lower.There exist some rejection rate for the flexibles,but Insulated flexible busbars can basically achieve 100%pass rate.
