EN50288-7 Cables
XLPE Insulated, LSZH Sheathed Instrumentation Cables

PE Insulated, PVC sheathed, CWb screened Instrumentation cables (Multipair)

re-2Y(c)Y 90°c / 300V

APPLICATION

EN 50288-7 cables are used for transmission of analogue and digital signals in instrument and control systems;

allowed for use in zone 1 and zone 2, group II, classified areas (IEC 79-14), not allowed for direct connection to

low impedance sources, e.g. public mains electricity supply.

Recommended for indoor and outerdoor installation, on racks, trays, in conduits, in dry and wet locations; not for

direct buiral.

Recommended for use as fire protection messure for people and important material assets.

CABLE CONSTRUCTION

Conductor: Annealed copper solid or plain copper stranded to IEC 60228 Class 2.

Insulation: PE compound as per EN 50290. 2-23.

Pair:Two conductors twisted to form a pair

Lay-up: Pairs laid up in layers of optimum pitch

Separator: Polyester tape

Overall Screen: Tinned copper wire braid

Outer Sheath: Thermoplastic PVC compound as per EN 50290-2-22. UV resistance, hydrocarbon resistance, oil

resistance, anti rodent and anti termite properties can be offered as option. Compliance to fire performance

standard (IEC 60332-1, IEC 60332-3, UL 1581, UL 1666 etc) depends on the oxygen index of the PVC compound

and the overall cable design. LSPVC can also be provided upon request.

COLOUR CODE

Insulation: Black / White, continuously numbered on white core(1, 2..)for multipair.

Outer Sheath: Black or blue for intrinsically safe systems

Physical AND THERMAL PROPERTIES
