Nexans has developed a new technology for fire-resistant cables by combining Mica taping with ceramic forming silicone rubbers.
The France-based company says the Infit technology combines the best aspects of Mica taping and silicone rubber but avoids the complications linked to both.
“A simple way to transform a standard cable into a fire-resistant cable is to add one or several mica tape layers between the copper conductor and the polymeric insulation,” the company told European Plastics News. “Nevertheless, the removal of the insulation for the cable wiring is difficult and makes this solution not user friendly.”
Silicone rubbers, on the other hand, are too easy to remove so display poor tear resistance, says Nexans.
Nexans therefore created Infit to combine the mechanical resistance of the mica tape insulation with the easiness of installation of silicone.
The technology will be especially useful for protecting security systems such as audio alarms and video surveillance cameras, which will be able to function for a certain time after the fire has started, says Nexans, although the company did not specify for how long.
Infit cables are already available in Switzerland and Sweden for building and marine installations. The company hopes to roll the technology out across its global markets during the coming year.
