LSZH Flame Retardant Overall Screened Instrumentation Cables (Multipair)
RE-2X(St)H
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.
