Read about company. with this spread sheet you will be able to calculate busbar voltage drop and select the proper bus bar size. In practice, the replacement of copper by aluminium is not done on the basis of equivalent resistance or voltage drop but rather on that of equivalent heating; this amounts to multiplying the cross-section by 1.4 to 1.5 only, in order to take into account the improved cooling of the larger surface. The average resistance or temperature increase from 0.3 mm Al tab was 0.6 times higher than 0.3 mm Al tab irrespective of busbar selection. The shape and size are either flat strips, solid bars or rods that allow for more efficient heat dissipation due to the high surface area to cross-sectional area ratio. In power-intensive electrical applications, a busbar (often also spelled bus bar or bussbar) is a critical element for conducting significant current levels between functions within the assembly. (Described on page 9) It is this process that allows aluminium to be considered as a viable alternative where copper is predominant. Silver plate versus tin plate is a little different. Insulating Tube use of the tubing provides equipment designers an ability to reduce the air spacing between busbar heat shrink sleeve by providing insulation enhancement.
