EN 50288-7 Cables
APPLICATION
EN 50228-7 unarmoured LSZH sheathed cables are generally use for indoor installation and suitable for wet and
damp areas. Generally, EN 50228-7 cables are used within industrial process manufacturing plants for
communication, data and voicetransmission signals and services. Also used for the interconnection of electrical
equipment and instruments, EN 50228-7 LSZH sheath can reduce toxic smoke and fume emission.
