Application

The 300/500V Mica+XLPE Insulated & LSZH Sheathed Fire Resistant Fire Alarm Cables are designed, manufactured and tested as data transmission cables for emergency services. These are primarily intended for for indoor instrumentation and control cabling, electrically noisy environments and fire alarm systems in office buildings when high frequency signal transmission has to be assured in the event of a fire.

Standards:

Basic design to BS 7629-1

COLOUR CODE

Insulation Colour: According to IEC 60189-2 (other colour code on request).
Sheath Colour: Colour red (other colours on request).

Physical AND THERMAL PROPERTIES

Temperature range during operation (fixed state): -30°C - +90°C
Temperature range during installation (mobile state): -20°C - +50°C
Minimum bending radius: 8 x Overall Diameter

construction

Conductors:

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

Insulation:

Mica glass tape covered by extruded cross-linked XLPE compound or cross-linked 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.

Overall screen:

Aluminum/polyester tape with tinned copper drain wire.

Outer Sheath:

Thermoplastic LSZH compound
