Fire Resisting Cable

Fire Resisting Cables

Fire Resistant Overall Screened Instrumentation Cables (Multipair)

RE-2X(St)H...CI

APPLICATION

The unarmoured LSZH sheathed cables are generally used for indoor installation and suitable for wet and damp

areas. Generally, the cables are used within industrial process manufacturing plants for communication, data

and voice transmission signals and services. Also used for the interconnection of electrical equipment and

instruments, the LSZH sheath can reduce toxic smoke and fume emission.
