Sheaths: Protection and insulation for your cables and components

What is a sheath?

The ducts are flexible or semi-rigid envelopes designed for protect, isolate or organise cables, wires or electronic components. They are used in a wide variety of industrial sectors: electronics, rail, automotive, aeronautics, energy, automationetc.

 

There are several types of duct, each meeting specific requirements: thermal, mechanical, electrical, electromagnetic or chemical. Some ducts are heat-shrinkableothers are braided, armoured or reinforced to ensure level of protection adapted to the environment use. 

Advantages of ducts

The use of a technical enclosure ensures that the safety, durability and compliance of your installations or assemblies: 

  • Mechanical protection against impact, friction and crushing. 
  • Electrical and thermal insulation to secure the facilities. 
  • Resistant to chemicals, UV, moisture and flames. 
  • Reduction of electromagnetic interference (EMI/RFI). 
  • Easy integration into cable harnesses and wiring harnesses. 
  • Improved component life. 
  • Professional appearance and clean finish assemblies. 

Aeronautics and space 

Sheaths are used for protect on-board cable harnesses against heat, vibration and short-circuit risks. Models lightweight, self-extinguishing and low-smoke are often required in these critical environments. 

Automotive, industrial vehicles and rail 

  • Organisation of engine or cabin wiring 
  • Thermal protection in hot zones (turbos, manifolds) 
  • Reducing electromagnetic interference on multiplexed networks 

Electronics, electrical engineering and telecommunications 

  • Electromagnetic shielding for sensitive cables 
  • Mechanical protection in patch bays or cabinets 

Energy, automation, heavy industry 

  • Reinforced sleeves for abrasive or chemical environments 
  • Heat-shrinkable tubing for labelling, marking or sealing 
  • Sleeves for isolating connections or providing point protection 

Insulating sheath 

La insulating sheath is designed to prevent accidental electrical contact and protect against power surges. It is essential to ensure safety of equipment and operators. 

  • High dielectric strength
  • Complies with UL/CSA standards
  • Available in PVC, silicone, polyolefin, fibreglass, etc. 

Mechanical protection sheath 

Specially designed to withstand abrasions, impacts, crushing and tractionthe mechanical protection sheath extends the life of cabling, even in harsh environments (dust, liquids, high temperatures, etc.). 

  • Spiral, corrugated or smooth versions
  • In PA6, PET, stainless steel or polypropylene
  • Quick and easy installation with compatible accessories 

Heat-shrinkable tubing 

La heat-shrinkable tubing shrinks under the effect of heat (generally from 80-120°C) and ensures a high level of stability. insulation, maintenance or precise marking. 

  • Shrink ratio from 2:1 to 6:1
  • Sealing, marking, weld protection
  • Can be used manually or in automated processes 

Braided sheath 

Flexible, lightweight and highly resistant, the braided sheath is ideal for bundles of cables that are dynamic or exposed to abrasion. The braided design also allows the components to breathe easily. 

  • PET, aramid, fibreglass or metal braiding
  • Thermal resistance up to +200°C
  • Highly flexible cable routing with connectors 

Electromagnetic shielding sheath 

La electromagnetic shielding sheath is designed to block or reduce electromagnetic interference (EMI/RFI) sensitive systems (telecoms, audio, radar, engine control, etc.). 

  • Tinned copper, aluminium and stainless steel braiding
  • Effective high-frequency attenuation
  • Complies with EMC requirements 

Sleeves 

The sleeves are pre-cut pieces of sheathing, used for locally isolate connections or protect junctions. They are available in heat-shrinkable, braided or armoured versions as required. 

  • Available in kits or individually
  • Easy to install without dismantling
  • Suitable for thermal, electrical or mechanical insulation

FAQ - Ducting

A sheath is a flexible or semi-rigid envelope used to protecting, insulating or organising cables.

It can be thermal, electrical, mechanical or electromagneticdepending on the materials and application. 

La sheath heat-shrinkable shrinks when heated to fixing or sealing a cable.

La braided sheathThis more flexible system makes it possible to mechanical beam protectionwith excellent breathability and flexibility. 

Shielding is used to reduce electromagnetic interference (EMI/RFI) in sensitive environments (electronics, radio, telecoms, aeronautics, etc.). 

Yes, some sheaths (fibreglass, silicone, PTFE) can withstand temperatures up to +260 °C or more, while providing mechanical protection or electrical insulation. 

Yes, as long as you choose materials resistant to UV, humidity and variable temperatures. Polyolefin, PET or reinforced polyamide sheaths are often used for outdoor installations. 

A sleeve is a portion of pre-cut sheathing, often used locally on a sensitive area (connection, welding). The sheath is generally a product in roll or reel form, for the continuous sheathing of a cable.
