Thermocouple Extension Grade Cable

Design Standards

Conductors:
Solid alloy wire, matched and calibrated to ANSI MC 96.1, standard limits of error, thermocouple extension grade.
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 conductors are twisted together to form a pair. The individually shielded pairs have a finished lay of 64 mm (2.5 in). Unshielded pairs have staggered lays to prevent electromagnetic interference and cross talk

Individual Shielding:
When specified pairs are shielded with 100% coverage aluminum/ polyester tape. The shielding tape is designed to provide total shield isolation from all other shields
Thermocouple pairs are provided with a layer of clear polyester tape under the shielding tape and have a solid tinned copper drain wire. A stranded tinned copper drain wire is optional
Conductor Identification:
The individual conductor insulation is colour coded as per ANSI specifications for proper identification of the ANSI cable type and distinction between the positive and negative wires
Overall Shielding:
Assembled pairs are overall shielded with 100% coverage aluminum/ polyester tape and a #20 AWG (0.519 mm²) seven strand tinned copper drain wire
Jacket:
90°C (194°F) to -40°C (-40°F) Fire Retardant PVC for unarmoured cables
90°C (194°F) to -40°C (-40°F) Fire Retardant Low Acid Gas PVC for armoured cables
Thermocouple cable is coloured as per the ANSI colour corresponding to the thermocouple alloy type contained in the construction. The inner jacket under the armour is black. Other colours are available upon request
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
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 currently recognized by the CSA
Armour Outer Covering:
90°C (194°F) to -40°C (-40°F) Fire Retardant Low Acid Gas PVC
Thermocouple cable is coloured as per the ANSI colour corresponding to the thermocouple alloy type contained in the construction. Other colours are available upon request
