Shrink sleeve

from Wikipedia, the free encyclopedia
Shrink sleeve for a telephone house connection

A shrink sleeve is a sleeve that is used, among other things, in telecommunications technology to close the connection of two or more cables in a water-tight and almost airtight manner.

It consists of plastic coated with glue or hot glue , which is placed around the area to be sealed as a mat and heated with a Bunsen burner . As a result of the heating, the sleeve contracts, the adhesive melts and thus seals.

Occasionally the term shrink sleeve is further specified with the term shrink sleeve or cable repair sleeve. Shrink sleeves can be closed tube-like structures, in which case they can only be attached to completely separate cables. There are also shrink sleeves that are open and are fixed on the side with a rail (picture); these can be used as a seal over leaks or for simple cuts without completely separating the cable. If, on the other hand, only a small defect on the jacket is to be repaired, for example, shrink sleeves are used in the manner described above.
