Heat shrinkable cable feed throughs switching from Ø5 to 160mm

• Waterproofness and superior protection : Once retracted, the sleeve heat shrinkable with adhesive ensures a sealed seal against water and dust. It protects the cable from vibrations and abrasion at the passage of the wall, where a simple rubber thread pass could show its limits in demanding medium.

• Adaptability and space gain : contrary to press-toup which requires precise threaded drilling and occupies space with its clamping nut, the cable pass heat shrinkable is easy to sit by slipping on the cable and then heating it. It fits the shape of the cable without additional rigid component, which reduces the congestion and allows to equip cables of various diameters with fewer references in stock.

• Enhanced electrical insulation : This type of crossing helps to maintain the electrical integrity of the system. Polyolethin cross-linked used offers excellent dielectric rigidity on many references, improving safety in the event of surge or incipient fire.

On the other hand, conventional towel presses (plastic or brass) offer a high seal index (IP68) and easy disassembly, but they can be heavy and not very flexible when installed. Heat-retractable cable passages eliminate metal parts and clamping points : no risk of release over time and no possible corrosion. However, they are for single use (we cut them to remove the cable), where a towel press can be reused. The choice therefore depends on the context : for a lightweight solution, integrated into a wiring beam and offering lasting maintenance-free sealing, the heat shrinkable often impose as a field-oriented solution.

Field implementation confirms the strengths of this component. For example, to move a beam of cables from the outside to a wet control cabinet, an industrial electrician opted for a cable pass heat shrinkable Adhesive rather than a classic toe press. After introducing the cable into the opening, he heated the sleeve : It has merged around the cable envelope and against the wall, creating a homogeneous seal. The presence of a thermo-fusible coating and a special surface ensured permanent watertightness, including when the opening was closed to the mortar in the case of a wall crossing. The result ? No infiltration or mechanical play, a cable held firmly in place, and a more compact installation inside the cabinet. This example illustrates how cable passage heat shrinkable provides a professional, narrative solution (each project tells its need) and resolutely oriented solution : a cable penetration problem is eliminated thanks to a simple component to be implemented, reliable in the long term and validated by the technical catalogues of large manufacturers.

Another example of the use of cable passage is the making of a connection between a tube ringed a cable. Indeed, every professional uses ringed tubes to walk his cables. But in ringed tube output (TPC type), how to manage cable output from the tubing Ringed ? Because there is an important space between the cable and inside the ringed tube. Through this space, pests (mulot, ...) can penetrate and snack the cable, water will enter, land, sand will penetrate the rhythm of climatic hazards, ... and the consequences will be disastrous. Cable passage is the solution. Its large diameter is two to ten times larger than its small diameter, which makes it possible to consider all the output configurations of a cable of diameter of a ringed pipe of diameter D, as long as D/d is less than 10 or D/d<10. The solution is fast, economical, easy to implement and sustainable.

As well as the themoretractable ends, the cable ends, the cable passage is a complement to the entire range of themoretractable ducts. It is both clever and simple, and will fit in specific situations.
