Fire sleeve: thermal protection and cable safety

Fire-resistant sheathing is a technical solution designed to protect electrical cables and components against high temperatures, flames and critical environments. It plays a vital role in securing industrial facilities by ensuring a Thermal and mechanical protection, and fire resistance in compliance with the strictest requirements.

Used in sectors such as rail, energy and automotive, fire-resistant conduit ensures service continuity and system security in the event of exposure to extreme conditions.

At ADDEV Materials, we support manufacturers in the selection and integration of appropriate thermal protection solutions, with a portfolio of technical sleeves from recognised manufacturers.

Fire retardant sleeve for industrial applications

In industry, fire-resistant sheathing is used for:

  • Protect electrical wiring
  • secure critical facilities
  • limit the risks of fire spreading
  • Ensure system continuity

It is indispensable in environments with high security requirements.

Comparison:

  • extreme thermal protection
  • Heat shrink tubing → standard protection
  • braided sleeve → mechanical protection
  • main electrical → general protection

The fire-resistant casing is designed for critical environments.

What is fire-resistant lagging?

The fire-resistant duct is a technical duct designed to withstand high temperatures and protect cables against:

  • direct flames
  • heat projections
  • extreme thermal environments

It is generally made of high-performance materials such as:

  • fibreglass
  • Silicone
  • high-temperature polymers

It offers a key solution for fire risk environments.

Fire sleeves vs. other solutions: What's the difference?

Fire sleeve vs heat shrink tubing

  • flame retardant
  • thermal protection standard

Fire sleeve vs braided sleeve

  • fire retardant → thermal protection
  • braided → mechanical protection

Fire-resistant cable management system vs standard electrical conduit

  • fire retardant → critical environment
  • standard → environnement classique

In a nutshell

  • Choose one fire sleeve for a Extreme thermal protection and fire safety
  • Consider other conduits for less demanding environments

How to choose the right fire-resistant duct

The choice depends on :

Fire resistance rating

The choice depends on :

  • maximum temperature
  • Exposure duration

Security review.

2. Type of material

As required:

  • silicone → flexibility + thermal
  • Fibreglass → high strength
  • polymers → specific performance

To be adapted according to the application.

3. Environmental constraints

To consider:

  • humidity
  • chemicals
  • abrasion

Ensures durability.

4. Standards and requirements

To check:

  • railway standards
  • industrial requirements

Ensures compliance.
