XLPE Insulated, LSZH Sheathed & Overall Screened Instrumentation Cables  (Multicore)

Multi-element metallic cables used in analogue and  digital communication and control, manufactured in accordance with British  Standard BS EN 50288 and European Standard EN 50288.
Instrumentation cables manufactured in accordance with BS EN  50288 are widely used in processing plants such as those  found in the petrochemical industry due to their ability to withstand electromagnetic interference. They are used for the transmission of signals in  instrumentation, control and communication applications.

BS EN 50288 covers the following range  of cables

RE-2X(st)H cable

XLPE insulated and LSZH sheathed

RE-2X(st)Y cable

XLPE insulated and PVC sheathed

RE-2Y(st)Y cable

PE insulated and PVC sheathed

APPLICATION

The LSZH sheathed cables are generally use 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.
