Zero Halogen, Low
Smoke (OHLS®) single core cable having enhanced
circuit integrity when exposed to fire. Tested
and approved by LPCB.
These cables are designed
for drawing into trunking and conduit where
a fire situation may pose a major hazard and
the maintenance of circuit integrity is a requirement.
To achieve optimum performance they should be
installed in metal conduit.
| Construction |
|
 |
| Conductors: |
|
Stranded plain annealed
copper wire conductor. |
| Insulation: |
|
Mica-glass
fire resistant tape covered by an extruded
layer of cross-linked Zero Halogen, Low
Smoke (OHLS®) insulating compound. |
| Physical Characteristics |
|
|
| Voltage rating (Uo/U): |
|
600/1000V. |

|
|
| Circuit integrity |
|
BS 6387 categories
C, W & Z (when applied to a single cable)
Exceeds IEC 60331 - 3 hours at 750°C
- when the test temperature was increased
to 950°C, equivalent to BS 6387 Category
C. (This test was also satisfactorily applied
to Sifer cable in an earthed metal conduit,
as per LPCB guidance notes). |
