EN 50288-7 Cables
APPLICATION :
EN 50288-7 unarmoured LSZH sheathed cables are generally use for indoor installation and suitable for wet and damp areas. Generally, EN 50288-7 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.
