Application

The 300/500V Mica+XLPE Insulated Individual And Overall Screened Instrumentation Cables are designed, manufactured and tested as data transmission cables for emergency services. These are used for data and voice transmission when high frequency signal has to be assured also in the event of a fire.

Standards:

Basic design to BS 5308/BS 7629-1

COLOUR CODE

Insulation Colour: White with black numberings.
Sheath Colour: Orange (other colours on request).

Physical AND THERMAL PROPERTIES

Temperature range during operation (fixed state): -30°C – +70°C
Temperature range during installation (mobile state): -20°C – +50°C
Minimum bending radius: 6 x Overall Diameter (unarmoured cables with silicone rubber insulation)
8 x Overall Diameter (unarmoured cables with XLPE insulation)

construction

Conductor:

Plain annealed copper wire, stranded according to IEC(EN) 60228 class 2

Insulation:

Mica glass tape covered by extruded cross-linked XLPE compound or fire resistant silicone rubber compound

Cabling Elements:

Insulated cores are twisted to form pairs with varying lay length to minimize crosstalk. Two-pair cable had four cores laid in quad formation.

Cabling:

Pairs are cabled together.In cables with 8 pairs or more, 4 pairs are assembled to form a bunch, the bunches are then cabled together.

Individual Screen:

Aluminum/polyester tape with 0.5mm2 screen (7/0.3mm) tinned copper drain wire.

Overall Screen:

Aluminum/polyester tape with 0.5mm2 screen (7/0.3mm) tinned copper drain wire.

Inner Sheath(optional):

Thermoplastic LSZH compound

Armouring(optional):

Galvanized steel wire armour

Outer Sheath:

Thermoplastic LSZH compound
