| Conductors: |
7 strand concentric, Class B bare or tinned copper
wire. Available in #20 to 14 AWG (0.519 to 2.08 mm²) for
150/300 V and #18 to 10 AWG (0.823 to 5.27 mm²) for 600 V |
| Primary Insulation: |
PVC compound - rated as 105°C (221°F)
dry, 75°C (167°F) wet and -40°C (-40°F) for
Type TW75-40 insulation |

insulation |
| Conductor Assembly: |
Two or three conductors are twisted together
to form a pair or triad. The individually shielded pairs and
triads have a finished lay of 51 mm (2 in). Unshielded pairs
and triads have staggered lays to prevent electromagnetic interference
and cross talk. |
| Individual Shielding: |
When specified, pairs and triads are shielded
with 100% coverage aluminum/polyester tape and a seven strand
tinned copper drain wire is used. The shielding tape is designed
to provide total shield isolation from all other shields. |
| Conductor Identification: |
Pairs are black, white and alpha numeric coded. |
| Triads are black, white, red and alpha numeric coded. |
| Overall Shielding: |
Assembled pairs and triads are overall shielded
with 100% coverage aluminum/polyester tape and a #20 AWG (0.519
mm²) seven strand tinned copper drain wire. |
| Jacket: |
Unarmoured - 90°C (194°F) to -40°C(-40°F)
Fire Retardant PVC |
| Armoured - 90°C (194°F) to -40°C(-40°F) Fire
Retardant Low Acid Gas PVC |
| Armouring (Optional): |
CSA certified interlocked aluminum or interlocked galvanized
steel armour is suitable for use in Hazardous Locations. In
Group B, C and D atmospheres, the individually shielded pairs
or triads may be extended through a sealing gland without removing
the shielding tape. These cables are marked HLBCD in accordance
with CSA C22.2 No. 174 |
| Served wire armour consisting of strands of galvanized steel
wire wound concentrically over the jacketed core is available
and is recommended for vertical riser applications |
| Zetabon® is a hermetically sealed aluminum barrier integral
with a bonded outer FR CPE jacket and is recommended for use
in direct burial applications. Please note that this armour
is not presently recognized by the CSA. |
