Fire protection for cables
Fire protection for cables – retrofitting instead of replacement
Problem 1: Retrofitting Halogen-Containing Wires and Cables: Many existing buildings contain older, halogen-containing wires and cables alongside modern, halogen-free cables. In the event of a fire, these release harmful, corrosive gases – a significant risk to people and equipment. A complete replacement is often not economically viable. Therefore, solutions are needed to retrofit halogen-containing cables , for example, by sheathing, sealing, or enclosing them.
Problem 2: Fire protection for halogen-free cables : While halogen-free cables are safer than halogenated cables because they do not release toxic gases, they are more flammable and not self-extinguishing. (See: Electronics Practice: Fire protection with halogen-free safety cables and wires )
Problem 3 Explosion protection for cables and wires: In the area of chemical plants and critical infrastructure as well as in the area of military installations, explosion protection for cables and wires represents an important safety measure to minimize the effects of explosions.
Advantages of retrofitting fire protection for cables and wires:
- Fire protection for halogenated cables and wires
- Easy retrofitting – ideal for existing buildings
- Additional mechanical protection and explosion protection through protective conduits for cables and wires in industrial and technical areas as well as for 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 dangerous fumes can be significantly reduced – without having to replace the cables .
Possible fire protection measures for cables:
✅ Cable routing in flexible fire protection conduits
The fire-resistant conduit offers protection against explosions, impacts, and high temperatures and is suitable for various applications, including retrofitting fire protection measures for halogenated cables. The conduits are available in two versions: fire-resistant (FR), ideal for fresh water, seawater, and fire suppression 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.
