Zero Halogen, Low
Smoke (OHLS®) cable with stranded copper
conductors and a protective armour layer. Manufactured
to BS 7846. Tested and approved by LPCB and
BASEC.
These cables offer the advantages
of an armoured 600/1000 Volt rated, zero halogen,
low smoke cable with circuit integrity. They
are intended for use in installations where
vital circuits are required to continue operation
in the event of the outbreak of fire. Firetuf
Power is particularly suited for use in public
buildings and constructions (such as hospitals,
theatres, shopping developments, tunnels, mass
transit railways, oil & petrochemical plants,
power stations and computer installations) where
the danger to life, equipment and structures
may be greatly increased in the event of a power
failure due to fire.
Also available in unarmoured design. Details
available upon request.
| Construction |
|
 |
| Conductors: |
|
Plain annealed stranded
copper conductors. For sizes up to and including
35mm2 these are circular. Shaped
conductors start at 50mm2 with
the exception of 2 core cables where shaped
conductors start at 25mm2. |
| Insulation: |
|
Mica-glass fire-resistant
tapes, covered by an extruded layer of cross-linked
polyethylene. |
| Binder: |
|
Polyester tape. |
| Bedding: |
|
An extruded layer
of Zero Halogen, Low Smoke (OHLS®) compound. |
| Armour: |
|
Single layer of
galvanised steel wires. |
| Sheath: |
|
Thermoplastic Zero
Halogen, Low Smoke (OHLS®) compound. |
| Physical
Characteristics |
|
|
| Voltage
rating (Uo/U): |
|
600/1000V. |
| Operating
temp: |
|
-40°C to +90°C
(The cable should not be flexed when
either the ambient or cable temperature
is below 0°C). |
| Min. bending
radius: |
|
8 x overall diameter
of cable. |
| Note:
In the event of a fire, the increase in
impedance may require consideration to the
installation of larger conductor sizes,
to accommodate motor starting loads and
the performance of protective conductors. |
