Sleeve: protection and insulation solution for cables

What is a sleeve?

Le sleeve is a sheathing accessory used to isolate, protect or identify a cable or an electronic component in a way that localised. 
Unlike conventional sleeving, which comes in a roll, the sleeve is Pre-cut or packaged to orderenabling rapid, targeted implementation during installation, maintenance or industrial assembly. 

There are different types of sleeves depending on their technical function (insulation, mechanical, thermal and dielectric protection, marking, etc.) and their material (polyolefin, silicone, fibreglass, polyester, etc.). 
The sleeve is a a strategic element in securing harnesses and connections in critical industrial environments.
