The problems in using busbar heat shrink tubing.

1. Bending part with wrinkle. The solution is contraction the linear part first, and then bake from the curved periphery to the inside, while a person on the other end with a little force stretching the tube, it can solve the problem of wrinkles.

2. Cracking: the causes are: Copper burr or cutting edge of tube is not smooth, not even heating lead to serious local heating baking, or the quality problem of heat shrinkable busbar tube itself, such as the radiation is too high, too low tensile strength of tube, the tube surface defects such as small needle eyes,etc.


3.Some times, there are some air bubble between the copper bar and the heat shrinkable busbar, the main reasons are: 1) do not shrink from one end to the other end of tube, or shrink from the middle to the two ends according to the requirement of operation instruction. This method helps to exclude air, 2) without preheating to the copper bar, but shrink the tube on the copper bar directly


The most problems when heated is bending shrinkage will appear rupture, the solve method is heating the out part of bent first, and then heated the bent inward.
