Meeting the demands of today's fire engineering systems.
By utilisation of high performance materials, Draka has now enhanced the circuit
integrity performance of this design of 600/1000V SWA armoured power cable so as to
meet the most onerous requirements of BS7346-6 : 2005 - “Components for smoke and
heat control systems - Part 6: specification for cable systems”.
The new standard
defines fire performance requirements of various types of fire rated cables in
maintaining circuit integrity for life safety, fire fighting and property protection systems.
Fire Safety systems include automatic fire suppression facilities, fire detection and
alarms, fire compartmentalisation, smoke control and ventilation, sprinkler and wet
risers, ventilation and shutters, fire fighting lifts etc.
All these systems require secure power supplies in the event of fire and the result of
emphasis on the performance of the existing generation of power cables has highlighted
the need for enhanced performance.
Firetuf Powerplus meets the specified requirement of the constructional standard
BS7846 and in providing enhanced circuit integrity preserves the handling and
installation characteristics of a wire armoured design.
The Building Regulations Approved Document B on fire safety was revised on 1st April
2007 and this now specifies fire performance in accordance with BS7346-6.
Firetuf Powerplus can be specified with confidence in meeting the demanding
performance required to support modern fire engineering systems in today’s buildings.
| 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. |

Firetuf Powerplus designs achieve the highest rating of 120 minutes when subjected to integrated testing involving direct impact and high pressure
water spray. The details of this test are currently documented in Annex B of BS7346, but will soon be published as a stand alone standard BS8491.
