Extensible braided sleeve or Spiral wrapping band

This is probably the variant of tubing The most widely used expansible. Made of interlaced polyester monofilament, it opens widely when compressed in length, and tightens as soon as released. Its main advantages : excellent resistance to abrasion while remaining very light, and a great flexibility that facilitates its installation even in the corners. In an electric motor or cabinet, the braided sleeving keep the cables well grouped by avoiding friction against the walls. Many study offices also plebiscite it for visual rendering : a beam covered with a braided sleeving is clean, well organized and gives an impression of professional work.

Another alternative is the spiral wrapping band (or wound) is presented as a plastic ribbon wrapped in the shape of a helical spring. It does not completely protect each wire over its entire surface, but it effectively groups the conductors and, above all, offers the possibility to pull a cable out at any place of the beam. Maintenance technicians appreciate it for this reason. : Needless to disassemble the entire beam to add or remove a cable, just slightly spread the turns in the right place. Reusable, this tubing allows you to insert or remove threads when you like. It is frequently found in workshops and computer science, where wiring configurations often change, as its installation and removal are fast and without tools.

The market offers other models of expandable ducts, less visible at first glance but very useful in particular cases :

• Braided sleeving Fireproof PET (self-extinguishing) – These sheaths combine flexibility and fire resistance. Compliant with UL94 V0 (self-extinguishing) standards and often with rail standard EN45545, they are widely used in rail and aeronautics where fire safety is paramount.
• High temperature textile sheaths – Made from self-extinguishing materials (glass fibres, aramides...), they are designed for areas where heat or flame are risk factors. For example, they are found near motors or power circuits to protect cables in the event of overheating.
• Expandable elastomer sheaths (rubber, silicone) – Very flexible, they often serve as temporary protection. For example, they can be wired to prominent mechanical parts or wired beams during transport or handling in order to avoid hooks and damage. Once the installation is complete, these temporary sheaths can be easily removed.

To better illustrate the interest of these expansible ducts, here are two concrete examples from the field :

• Case 1 – Braided sleeving on an automotive beam : In an automobile prototyping workshop, the maintenance engineers dressed the engine beam with a braided sleeving expandable. The installation was fast and unadulterated : the tubing easily expanded to the necessary places (connectors, bypasses), then tightened to maintain all wires. Thanks to this protection, the beam was able to move closer to moving mechanical parts without risk of friction or wear. The final result is a well maintained and protected beam, giving the engine compartment a clean and professional look.

• Case 2 – Spiral wrapping band Computer environment : In a company computer room, a technician used tubing Spiral to organize a set of network cables and power supply behind servers. The cords were grouped in a few minutes using the spiral wrapping band, which removed the disorder of threads entangled. A few weeks later, when additional equipment had to be added, the technician simply removed the turns of the tubing at the place desired to bring out a new cable, without having to disassemble any installation. This flexibility saved valuable time and kept a well-ordered computer bay despite the changes.
