  • The Application of this cable is circumstances where a very high degree of fire safety is required as the cable will function during a fire,has limited fire spread,has limited smoke generation and is halogen-free. The typical installation environment is indoor and indoor/outdoor in and between public buildings,in tunnels,metro lines and other places where one need very high degree of fire safety and support for critical communication. This cable is also suitable for shipboard application.The steel tape armouring makes the cable rodent proof.The primary means of installation are on cable ladders,raceways and cable trays. The cable may however also be directly buried. The cable can be installed outdoor in the open, but shall be not be installed directly exposed the sun.
