Heat shrink tubing

Release date:2019-01-08 author:admin Click:

Suzhou Feibo Heat and Cold Shrinking Products Co., Ltd. is a professional manufacturer of high and low pressure heat shrink tubing. Our heat shrink tubing are divided into 1kv, 10kv and 35kv. With the different pressure levels, their using range is different. But the effect is similar, they all play the role of protective insulation.
In this issue, we will discuss which need to be paid attention to when heat shrink tubing is placed on the copper strip.
I believe that most customers will find that after heat shrinking will be cracked in a short time after purchasing and using the heat shrink tubing. The main reason for this is that on the copper row, we found that the copper row during the production and storage process, it is easy to cause surface scratches and some uneven burrs. If heat shrink tubing is placed over these burred copper bars, the heat shrink tubing will be scratched and cracked after a period of operation. The main reason is that heat shrink tubing relies on a large internal stress to shrink, and our heat shrink tubing is soft when heated, so it is easily scratched. Therefore, before shrinking, it is necessary to check whether the copper-aluminum busbar has burrs and correspondingly treat the surface of the copper-aluminum busbar to be smooth, so that we can use heat shrink tubing
It may be found that when heat shrink tubing is heated, it is not closely attached to the copper strip, and foaming occurs in some places. The main reason is that because the copper platoon is not preheated, the heat shrink tubing is directly shrunk. When shrinking, It is gradually heated from the middle to the both ends, so that the internal air can be eliminated and it will not be removed.
The above is the problem that should be paid attention to when heat shrink tubing is heated on the copper row. Welcome to consult and suggest.
