Instrumentation Cables

Design Standards

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
XLPE compound - rated as 105°C (221°F) dry, 90°C (194°F) wet and -40°C (-40°F) for Type RW90-40 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.
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.
Armour Outer Covering:
90°C (194°F) to -40°C (-40°F) Fire Retardant Low Acid Gas PVC
Instrumentation cable standard colours are gray or intrinsically safe blue. Other colours are available upon request
