Problem 1: Retrofitting fire protection for halogenated cables

In older buildings, in addition to halogen-free cables, there are often also cables containing halogen in use. These are deployed in case of fire. highly toxic, corrosive gases free, endangering people, damaging electronic systems and massively increasing building damage.

A complete replacement of all lines is often not economical in practice. Therefore, the following are required: Retrofittable fire protection solutions, such as:

• fire-retardant sheathing

• fire-resistant seals

• Protective sleeves or enclosures for cables and wires

These measures reduce the fire load, delay the spread of fire and significantly improve personal safety – without interfering with the existing installation.

Problem statement 2: Fire protection for halogen-free cables and wires

Halogen-free cables are considered safer because they are safer in case of fire no toxic gases release. However, many halogen-free cables more flammable and frequently non-self-extinguishing. This can cause fires to spread more quickly along cable routes.

Additional fire protection is therefore also advisable for halogen-free cables, especially in:

• Escape and rescue routes

• Technical centers and data centers

• Industrial and energy plants

Retrofittable protection systems increase fire resistance duration and contribute to compliance with current fire protection concepts.

Problem statement 3: Explosion protection for cables and wires

In Chemical plants, energy infrastructure, industrial plants and military installations plays a role in addition to classic fire protection, also in the Explosion protection for cables and wires a crucial role.

Special protective hoses and enclosures can:

• reduce the effects of pressure waves

• Protect cables mechanically

• Limiting secondary damage to safety-relevant systems

In doing so, they make an important contribution to operational safety and the protection of critical infrastructure.

Retrofittable fire and explosion protection for existing cables and wires

With specially tested products, halogenated cables can be effectively shielded against fire and the emission of hazardous fumes can be significantly reduced – without having to replace the cables.

Possible fire protection measures for cables:

✅ Laying cables in flexible fire protection conduits

The fire protection hose offers protection against explosions, impacts and high temperatures and is suitable for various applications, including the retrofitting of fire protection measures for halogenated cables. The protective hoses are available in two versions: fire-resistant (FR), ideal for fresh, sea, and fire-fighting water, and fire- and oil-resistant (FOR), suitable for liquid hydrocarbons and aggressive chemicals. Installation is quick and easy, requiring no welding or hot work, and the system is virtually maintenance-free after installation.

• Robust sheathing of flammable cables in a flexible protective sleeve

• Offered diameters of the protective sleeves:

  • 1 inch (approx. 25 mm)

  • 1.5 inch (approx. 38 mm)

  • 2 inch (approx. 51 mm)

  • 4 inch (approx. 102 mm)

  • 6 inch (approx. 152 mm)

In addition, we offer Robust split cable protection tubes with half shells for installation in the ground, also for retrofitting or for construction sites.
