Use of heat shrinkable tube

Before use to determine the correct specifications of the heat shrinkable tube and the heating tool, and the specifications of the heat shrinkable tube often slightly greater than the need to protect line position, just a little bit big to tighten, use the steps for the interception of a suitable length of heat shrinkable tube of the heat is used after the location of the cable to protect tools and special heat blower on the heat shrinkable tube of a uniform heat shrink. 

Before shrinking, it needs to be fixed simply with hands or tools, but after shrinking a little, it can be loosened and fixed with a hot fan until all contraction is completed.

Note for use: when choosing the heat shrinkable tube, the specification should not be too large to avoid too long heating time or too large shrinkage; When heating, pay attention to control the temperature and orderly from one end to the other end of the heating or from the middle to both sides of the empty tube air so that there is no bulging phenomenon.
